In the "Principal Directions for Development of the USSR National Economy in 1976-1980" the need was pointed out for the expansion of research with ~ the use of space vehicles in studying the earth's natural resources. Re- mote aerospace methods are objective fiigh-speed automated systems for the I collection and processing of information on the state of soils, agricul- tural fields and sown areas. The control of agricultural production can be organized more effectively on this basis. One of the new directions in the field of use of aerospace methods for the study of soils and sown areas of agricultural crops is the development of multizonal and multispectral aerial and space surveys. In ttiis method one and the same sector of the earth's surface is photographed simultaneously in several narrow spectral ranges. As a result photographs are obtained which carry the maxtmum infoxmation concerning the soil cover and agri- cultural crops. The use of infrared photographic, photoelectronic and radar surveys is high- ly promising itl agriculture (for studying the snil cover and sown areas). A radar survey caxi be used in the absence of visibility (through clouds and even at nighttime). Using radar photographs it is possible to inter- , pret moisture cantent, some structural elements and the diversity of the - soil cover, tl:e makeup of the upper fiorizons and the types of agricultural crops. A space surveq of the soil cover and sown areas of agricultural crops, in ' compariaon with an aarial survey, for the first time is making it possible to see soils and sgricultural crops objectively simultaneously over ex- tena4ve areas, individual mountain systems and the vertical zonality of - the soil-vegetation cover and tfie natuie of irrigation and drainage systems as a whole. Another important ctiaractertstic of a space survey is that on space piiorographs there is an objectfve generalization of the aoil cover; in addition, these photographs ID.-ske it gossible to interpret the soil cover in. individual, frequently in.accessible regions. The use of - space materials wi11 assist in awore thorough study of soils. _ Z FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 One of the principal and fundamental characterietics of a survey from space is the routineness in the collection of information on the state of the soil cover, the nature of snow melting, the development of eros- ional processes and the state of agricultural crops at a national scale. Still another characteristic of a space survey is the poasibility for a rapid repetition of the survey. This is especially important for judging rapidly developing dynamic soil-agricultural processes transpiring at the earth's surface. - Aerospace (remote) methods, with the use of corresponding detectors carried _ on flight (air and space) vehicles, on the one hand register the reflec- - tion of sunlight frum soils and vegetation, and on the other hand, detect the characteristic radiation of the soil-vegetation cover of the earth's surface. The use of aerospace methods is based on the fact that the absorptiion, emis- sion, scattering and reflection of electromagnetic energy by different soils and sown areas is selective and specif ic for each soii and agricultural , crop. _ The interpretation of the soil cover is carried out on the basis of its im- age on aerial and space photograplis, including multizonal photographs. Studies are made of the tnterpretali.ility and possibility of using aerospace photographs taken in different zones of the electromagnetic spectrum for _ investigating the soil cover and keys are tieing developed for soil inter- pretation. Investigations of soil interpretation in tce field were carried out in the - territory of the steppe, dry steppe and desert zones of our country. _ Investigations in the field of interpretation of the soil cover, agricul- tural crops and virgin land vegetation have been made using black-and- white, color and spectrozonal aerial photographs, mu]:tizonal aerial photo- graphs (green, red, IR zones), obtained using an AFA-39M outfit during the survey of 1973-1975, multispectral aerial photographa obtained using a scanner, black-and-white space photographs from the "Soyuz-9," "Salyut-1" and "Salyut-4," multizonal space photographs from the "Soyuz-32," "Salyut- - 4" and "Soyuz-22" and from the "Meteor" experimental satellites. In this monograph we also give an analysis of foreign black-and-white and - color space photographs from the "Gemini" and "Apollo" vehic3.es and multi- spectral space photographs in four zones Qf the spectrum J'rom the ERTS - satellite "Landsat," obtained for the territory of the USSR and foreign countries. The joint use of aerial and space photogr3phs is the optimum variant for - interpreting images of the soil cover aiid vegetation. The interpretation _ of aerial photographs is used most successfully in key sectors for study- ing structural elements of tfie soil cover. However, in the interpretation 4 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 - FOR OFFICIAL USE ONLY of space photographs soil sc3.entists me'et with a generalized image of the soil surface. The investigation and interpretation of serial and space photographs begin with a preliminary office work period, the importance _ of which incr.eases with the use of multizonal photographs and stereoscopic, optical-electronic and photometric apparatzis for the processing of photo- - graphs and films. The interpretation of aerospace photographs included field suxface work for investigating the soil cover and sown areas of agricultural crops and checking the results of office interpretation. In the work use was made of materials from the book of the history of fields, taking into ac- count data on crop yields. In office and field interpretation, in addi- - tion to data from field investigations, use was made of existing soil and - topographic maps of different scales, plans for the distribution of agri- -cultural crops and materials in the literature. In the analysis o� aerospace materials use was made of the stereoscogic re- - search xnethod, employing a stereoscope and an interpretoscope. The spectral - reflectivity of the soils was measured using air-dried samples, employing an SF-10 spectrophotometer. In tfie investigation of aerospsce photographs use wss made of an MF-4 microphotomQter and the quantitative visual-instru- mental interpretation method, employing the.modern "Kvantimet-720" elec- = troriic-optical image analyzer. Chemical analyses of soils were made in the Mass Analyses "Lahoratory of the Soils Institutp. In addition to experimen- _ tal surveys made by the Soi,ls Institute, extensive use was made of mater- ~ ials from multizonal experimental flights of the Space Research Institute - USSR Academy of Sciences. A considerable part of the space photographs was - furnished by the State Center "Priroda" of the Main Administration of Geo- desy and Cartogr.aphy of the.US5R Council of Ministers and the State Sci- = entific Research Ceater for the Study of Natural Resources of the USSR State Committee on Hydrometeorology and Er.vironmental Monitoring, 5 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 Chapter 1 HISTOR'Y OF AEROSPACE METHODS FOR STUAYING SOILS ~ The initial stage in the development of remote methods for investigating soils is related to the use of aerial surveys. Aerial photographic sur- veys in soil science, introduced in tlhe 1920's, in a relatively short his- torica"1 period made an enormous strlde forward. Development and Introduction of Aerial Methods for Stu3y of the Soil Cover - (1927-1950) Y The first experimental studies in the Soviet Union on the use of an aerial survey for soils and agricultural purposes were carried out in the Fergana _ valley in 1427. ~ The importance of ar. aerial photographic survey as a new method for study- ing natural resources was outlined by Academician A. Ye. Fersman (1928). ' He wrote that an aerial s~lrvey gives a precise and objective photographic : image of a territory. It makes it possible to repeat surveys during dif- - ferent periods and ascertain the changes which are introduced by nature and mar.'s eGOnomic activity in the course of a definite time period. In 1927 in the United States (Bushnell, 1927, 1929) aerial phutographs were _ used in soil mapping for the state of Indiana. It was establiahed on the basis of the first investigations that areas of uniform soils could be discriminated reliably on aerial photographs and then, employing a panto- graph, cQUld be plotted on a map base. - At a.pproximately the same time attention was given to the use of aerial methods in Australia (Prescott, Taylor, 1930). - Large-scale soils investigatians assumed a broad scale in the USSR during these years. During the years 1929-1931 alone soil maps at a scale 1:10,000, - 1:25,000, 1:50,000 were compiled for a territory with a total area of about 50,000,000 hectares. Materials from aerial photographic surveys began ta be used witti increasing frequency in a study of soils. In investigating the territory of Don River plavni (low areas covEred with reeds and trees) - (Levengaup-L, 1932) it was found that aerial photographs have a consider- - able advantage over plane-talile surveys with plotting of contours. The aerial photographs clearly depicted all 'tlie details of the vegetation 6 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-00850R000300054424-7 - FOR QFFICTAL USE ONLY - ~ covPr, this taeing reldted to the charactex of thR soils to be mapped. As _ a result, the houndar-! es hetureen the soil var.ieties were draum with a high degree of accuracy. Among the earliest soil mapping studies with the use-of materials from aer- ial surveys we must also include the soil aurveys of Giprovod (State Inst- _ - itute for the Planning of Water Resources) in 1930-1931. Aeri.al photograph- ic materials were used both as.a_base arzd for the interpretation of the soil cover. During 1931-1932 aerial photographs were suGCessfully used in - a soil melioration survey of the Volga-Akhtubinsk floodplain and the Vclga delta. _ In 1931 Academician L. I. Prasolov wrote that the best prospects for the ' use of aerial methods in soil science werE opening up ir, the field of in- = vestigation of inaccessible swampy regions and in compiling detailed soil _ snaps of cultivated regions. In 1933 he indicated that an aerial photograph- - - ic survey is a new method for carrying out soil investigations. During 1932-1940 aerial photographs were used in work on the tnapping of soils carried out in the Ukraine and the Urals, in Kazakhstan, Siberia, . Central Asia and in other regiorts of our country. It was established on _ - the basis of these studies that in comparison with surface survey maps the - principal advantage of materials from an aerial photogzaphic survey is as- surance of orientation in the terrain, ar_curacy and detail in plotting the houndaries of areas of uniform soil. Work productivity in soil mapping of a territory with.the use of aerial methods dcubles or triples. iL Abroad, fn studies involving the use of materials from an aerial photograph- - ic survey for investigating the soil cover (Belcher, 1948; Frost, Woods, - = 1948; Troll, 1939), mention is made of the need for using tTie interrela- - , tionships existing between soils and landscape elements in tnterpretation = work. For Qxample, using the relationship between the soj.l and vegetation y cover, by means of interpretation of vegetstion it is possible ro deter- - mine the soil cover of the investigated territory. In soil investiga*ions _ the materials from an aerial phctographic survey aerve for supporting, as- siating and deepening work on tfie m.apping of a territory. During the period _ of development and introduction of aerial methods for study of the soil - - covex it was establislied by a number of Soviet and foreign researchers that - when using aerial photograghs there is an increase in the accuracy of the = ~ results and a decrease in the cost of the work. Aeria? MethDds in Soil Mapping Work in Di�ferent Natural Zones of the Country (1950-1970) - During the post-war period, hoth in the Scsviet Union and abroad, aerial - methods came into extensive use for the purpose of study of the soil cover. - - This stage is ctaracterized by tY;e use of already available aerial photo- _ graphic materials in the m,apping.6f soils, as well as the formulation of - _ sgecial tnvestiaations. ~ 7 FOR OFFICIAL USE ONLY } APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-00850R000300054424-7 - In 1950, in a specially organized lahoratory fox the large-scale mapping - of soi'ls a* the Soils Institute imeni V. V. Dok-uchayev, under the direc- tion of Yu. A. Liverovskiy, work was initiated on a method for compiling large-scale soils maps on the basis of aerial methods in different soil- - gEOgrapfiic zones of our country. The aeri8l survey was regarded as a new method making it possilile to compf.le soil maps of a fundamentally new content. Similar work in the field of soil aerial methods was initiated : during this pEriod in the Aerial Metfiods Laboratory USSR Academy of Sci- ences and at Moscow State Ur,iversity. The tasks and possibilities of such _ = work were dealt with in an article by A. V. Gaveman and Yu. A. Liverovskiy - (1953). In this study the authors pointed out the need for developing a method for the interpretation of aerial photographs for study of the sail - cover, the use of a special aerial survey color and spectrozonal, study of the spertral refiectivity af soils. During the post-war period in all the Principal soil-geagraphic zones of - our counrry investigations were ma.de fcr studying the distinguishing char- - acteristics o.f the interpretation af soils and their mapping on the basis - of aerial materials. In the studies of Soviet specialists published dur- _ ing this period there were investigations of the possibility of interpret- _ ation and usP of materials from an aerial survey for the study and mapping of the soil cover in the forest, wooded steppe, steppe, dry steppe and = desext zones of our countrv. _ The dependence between spectral brightness and humus content, mechanical composition, moisture content, nature of the surface and other soil factors - and properties was Pstablished. The landscape principle for interpretation of the soil cover was proposed. The problems involved in large-scale and " medium-scale soils and soils-meliorative surveying were considered. The influence of natural and technical conditians for carrying out this work - was established. Color spectrozonal aerial surveying of the soil cover was ~ beginning to acquire great importance; with respect to the degree of in- _ terpretability of soils this had considerable advantages over a panchrom- = atic survey. _ _ The considered period (1950-1970) saw the beginning of the use of aerial . methods in special soil investigations: erodability of the soil cover, - soil melioration work and soils regionalization. A ntueber of generalizing _ manuals were devoted to the methods employed in the mapping of soils on - the basis of aerial methods. It was exceptionally important to introduce ~ a course on the interpretation of soils into the curricula of universities and other hip;her educa tional institutions. - Color spectrozonal aer ial survcrying began to come into increasing use in ~ studies for the mappiixg of soils. Among the color films Soviet spectro- - zonal and Amerir.an (Ko dak Company) films have good properties for making = surveys in natural and "fictitious" colors; Czechoslovakian, Belgian and SwiSS films have good natural reproduction of colors. _ g - - FOR OFFICIAL USE ONLY ~ APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-00850R040340050024-7 FOR OFFICIAL USE ONT-Y Work done in this stage dealt with the possibilities of using co'lor spec- = trozonal photographs for the interpretation of soil cover in soddy-podzolic, gray forest, chernozem and cfies.tnut zones. The advantages of their use in comparison with panchromatic photographs were clarified. In the socialist - countries, especially in East Germany, Soviet spectro2onal film has been us.ed s.uccessfully in the interpretation of ineadow soils (Asmus, Reinhold, 19656). _ In 1952 the Scientific Research Institute of Soils and Fertilizers (Uni*_ed States) generalized and systematized the requiremenCs imposed on an aerial survey used in study of the soil cover (Swanson, 1954). It was established that a scale of 1:20,000 *aas in tFLe widest use for the mapping of soils. _ The time fer the survey is selected in dependenee an the region, but in ~ most cases an aerial survey is made in spring when the soil is freed of - snow and has a minimum vegetation cover. In addition to individual studies of the use of aerial methods in a soil survey and on the interpretation of soils, during this period special man- uals on the engineering 'Lnterpretation of soils (MANUAL OF AIItpHOTO INTER- INTERPRETATION..., 1953) and on general interpretation problems (MANUAL OF PHOTOGRAPHIC INTERPRETATION, 1960, AERIAL PHOTOINTERPRETATION..., 1966) wPre published. The American Photogrammetric Society prepared and published a special man- ual on color aerial photographic surveying (MANUAL OF COLOR AERIAL PHOTO- GRAPHY, 1168) containing data on the use of color photographs in different branches of the natural sciences. In the United States, Sweden, West Germany and other foreign countries ex- ~ tensive use is made of a color aerial photographic survey on reversible color �ilm and printing on color reversible paper, which make it possible _ to ohtain a better image of color transmission than negative color film - (Gerberman, et al., 1971, Kufil, 1970), ; In Che USSR, United States, France and other well-developed countriQS work _ is being done on the compilation of aerial photograph keys, playing an im- .portant role in the office interpretation of soi1s. Ahroa.d the post-war period is characterized by the extensive use of aerial - methods in soil sr_ience. In a review report prepared for UNESCO (Vj,nk, - 1968) it was indicated that only during Yecent years has there been a more _ systematic and fundamental approach tu the problem of use of aerial survey - materials for study of the soil cover. In the United States during these _ years a cansidera.hle part of the agricultural areas was covered by an aer- ial survey at a scale of 1:201000; in addition to panchromatic films, in- = frachromatic films are used extensiwely in soil surveys. Soils are inter- I preted hoth in the office and in the field. Interpretation critexia have ~ now been developed for all soil varieties in zhe United States and the key ~ criterion for interpretation of the soil cover is the in,terrelationship , between soils and vegetation. Special investigations for the interpreta- tion of soils are made at a number of universities in the United States _ (Clark, 1957; Mui.r, 1955). 4 = FOR OFFICIAL USE ONLY i i APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 In ;iolland mucki academic and scientific resEarch work on the interpreta- = tion of soils was carried :out by the International Znstitute of Aer- - ial Surveying and the Earth Sciences (Veenenhos, 1956). - Much wcrk on tiie study an3 mapping of natural resources and soils was - done in France and other countries. Serious work on the study of the nat- - ural resources of the developing countries with the use of aerial methods was carried out during this period by the Sciences Department of UNESCO, whose general director over a period of years was V. A. Kovda, Correspond- ing Memher USSR Academy of Sciences. - In many foreign countries Great Britain, Australia, Belgium, Ho lland, - India, Italy, Canada, Mexico, United States, 'West Germany, France, Sweden, Japan aerospace (remote) methods were then used succsssfully in the study of natural resources, including the soil cover, when making a soil - survey. Firms fn a number of cotntries (United States, Great Britain, Hol- - land, Italy, Canada, France) carried out similar survey work in develop- - ing countries of. Asia, Africa, Latin America. The studies made by foreign specialists during this period outlined the characteristic peculiarities of interpretation of soils from aerial photographs, the good prospects for the use of aerial methods in study of the soil cover and the effectiveness of use of color spectrozonal photographs. During the considered period (1950-1970) of development of aerial methods in the IJSSR and foreign countries an ever-increasing role was played by - soil aerial mEthods in the mapping of soils carried out in different nat- - ural zones over the earth. Color and especially spectrozonal aerial photo- graphic surveying of soils was beginning to acquire ever-greater impor- - tance. Modern Stage in Aerospace (Remote) Methods in Soil Science and Agriculture _ (1970-1979) This period is characterized by improvement in the earlier developed in- terpretation methods and a changeover from description of the character- - istics of the investigated object to quantitative indices. - In the USSR a number of systematic manuals have been published on the mapp- ing of the soil cover with the use of materials from aerial surveys (KRUPNO14ASSHTABNAYA KAROGRAFIYA POCHV, 1971; Afanas'yeva, et al., 1977). Special fundamental investigations have been carried out for studying the optical properties of the landscape applicable to an aerial survey (Tol- ~ chel'nikov, 1974), and also an analysis of spectral reflectivity and soil colcr as indices of their properties (Karmanov, 1974). In carrying out an experimental soiZ aerial survey in our country and abroad great attention during these years was being devoted to the choice of tech- nical and natural conditions for carrying it out, s tandardization prob lems, 10 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY i preliminary and office interpretationy development of interpretation k.eys ' for soils in different geographical zones and the landscape interpretation _ method.

Kondrat'yev. - tJe can iiote the advantages of space methods for study of the environment - the globality, regularity, periodicity ann multisided nature of the ob- ~ servations, clarification of the relationships existing between natural features, the possibility of routine study of the dynamics of natural pro- cesses dnd phenomena and investigations of inaccessible natural regions. The introduction of space methods into geology, soil science, agriculture and other fields of science is creating new possibilities for study of natural resources, their space mapping, monitoring the state and preserva- tion of the environment. - Special investigations are being made for studying the possibilities of us- ing materiaZs from a space survey in the f-`.eld of soil science and agricul- _ ture. Using space methods it Is possible tc, determine the types of soils, evaluate moistening conditions, ascertain the areas of agricultural fields � and deterniine agricultural crops. R. Chevallier (1973), in generalizing the materials of work in Commission _ VII (Interpretation) at the 12th Congress of the International Photogram- metric Society in Canada, noted that when using surveys from satellites - the main problem is a study of the earth's natural resources, the develop- ment of optimum scales and condi.tions for the survey, the ca?-rying out of multisided surveys from satellites and aircraft, as well as the interpret- ation space images. In the United States investigations.in the use of space materials in the f ield of soil science and agriculture are being carried out by the Depart- - ment of Agriculture in collahoration uzith NASA (National Aeron.autics and Space Administration). During recent years one of the leading research studies sias the compilation of the first photomap (by the Division of Soil Mapping and Protection of the US Department of Agriculture) of the entire country on the basis of photographs from the ERTS satellite at a scale of 1:1,000,000. A total of 595 Fr~otograpfis in the red zone (0.6-0.7f,1.m) were used for this purpose. ; 11 ~ FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 = At Purdv.e Uni�:ersity (Indiana) M.

The first volume examines the theoretical principles and techniques used in remote surveys. The second volume is devoted to a photographic interpretation and use of remote methDds, including study of agricultural crops and soils. In Holland, at the International Institute of Aerial Surveying and the Earth Sciences the systematic training of specialists for study o.f soils with the use of remote methods is being conducted by D. Goosen and others. At the tdational Agronomic Institute in France investigations for the devel- opment of aerospace methods in the field of soil science and agriculture are being developed by M. C. Girard. In the USSR two centers have been established fo�r studying the earth's nat- ural resources using space vehicles: the State Center "Priroda" of the - Main Administration of Geodesy and Cartography of the USSR Council of Min- isters and the State Scientific Research Institute for the Study of Natur- - al Resources of the USSR State Committee on Hydrometeorology and Environ- mental Menitoring. The great possibilities and prospects for the study of natural resources _ over the earth which are opening up with the use of space photographs con- stituted the subject of discussion at international and national confer- ences iri different countries. In the USSR one of the first major scientific conferences for problems relating to study of the earth`s natural resources from space was the All-Union Scientific School held at the Space Research - Institute USSR Academy of Sciences in 1975 (LIBROKOSMICIIESKIYE ISSLEDOVANIYA ZEMLI, 1979). _ The problems involved in the use of remote methods in the field of soil science and agriculture have been discusse3 in many countries and insti- - tutions, specifically: at Houston (United States) at conferences on the use of artificial earth satellites for geographic investigations in 1965 and 1975 using the results obtained with the "Skylab" orbital stazion; at - 11 international symposia on remote sensing of the environment at the Utiiversity of Michigan; at international congresses of soil scientists - in Australia in 1968 and in Moscow in 1974; at the 12th International Con- _ gress of Photogrammetrists in Canada in 1972; at the 13th Session of COSPA.'t in Leningrad; at the Sth and 6th Congresses of the USSR Geopgraphical Society; at the 23d International Geographical Congress in 19176; at the 13th International Congress of Photogrammetrists in 1976 at Helsinki; at the In- ternational School in Rome and at other conferences. ~ 12 FOR OFFICIAL USE ONLY - APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 - FOR OFFICIAL USE ONLY Cooperation is developing between the USSR Academy of Sciences and NASA in the United States in the field of study of the earth's natural resources using space vehiclea. One of thQ directions is the use of these methods for investigation of vegetation, soils and land use. The exchange of sys- tematic attainments in this field between the USSR and the United States is of great theoretical and practical importance. In the People's Republic of Bulgaria, Hungarian People's Itepublic, German Demacratic Republic, t4ongolian People's Republic, Polisl People's Republic, Socialist Republic of Rumania and other socialist countries work is devel- = oping on the use of remote methods for study of soils and agricultural " crops. _ A session of the presidia of the All-Union Orcler of Lenin Academy of Agri- ~ cultural Sciences imeni V. I. Lenin and the Academy of Agricultural Sci- ences of the German Democratic Republic was he3.d in Moscow in 1977. There was discussion of prohlems relating to joint investigations of the use of multizonal space photographs taken with the MKF-6 camera for studying soils and agricultural crops. The modern research period is characteriaed by the use of different remote aerospace, including multizonal and multispectral methods for study of the soil cover and areas of agricultural crops in the USSR and in foreign. countries. 13 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 Chapter 2 - AEROSPACE SURVEY OF SOIT~-AGRICtJLTURAL RF.SOURCES AND EQUIPMENT FOR SUCH _ A SURVEY :A new method for the collection of information on natural resources has been developing during recent years in our country and abroad, especial- ly in the United States. It has been givpn the name remote sensing. This term was introduced in 1960 by the geographer Evelyn Pruitt (United States) - and is now being used throughout the xaorld. In this mathod, without direct contact with the studied object, by the use of instruments it is possible - to register electromagnetic waves reflected and radiated by the earth's surface from the flight altitude of an aircraft or aXCificial earth satel- lite (AES). a The totality of inethods used in investigations and in mapping from an air- - craft, artificial satellite, helicopter and other flight vehicles is known as aerospace methods for studying the earth's natural resources. The physical properties and characteristics of soils and agricultural glant- ings can be registered using different instruments in different zones of = the electromagnetic spectrum of wavelengths (Table 1). The visible spectrum of electromagnetic oscillations with wavelengths from 0.4 to 0. 7~ m is subdivided into different colors (Table 2). - Beyond the violet spectral region lies the ultraviolet, and beyond the red the infrared. Aerospace methods for studying the earth's soil and agricultural resources - aia subdivided into photographic and photoelectronic. During recent years ever-increasing attention of researchers working in the field of study of - natural resources has been devoted to the use of photoelectronic methods. On the basis of achievements in development of the latest technology these methods are finding ever-increasing application in such fields as geology, meteorology, agriculture, soil sciencey and others. An aerial survey is a survey of the terrain (from an altitude as little as hundreds of ineters to 20 lan) executed from flight vehicles using different _ surveying instruments operating in different zones of the el?ctromagnetic 14 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY spectru.no At the present time an aerial survey also includes a photoelec- tronic survey. A space survey of the earth results iA photographs and - traces of the earth's surface taken from altitudee greater than 80-100 km from different flight vehicles: research rockets, artificial earth satel- litea, automatic orbital stations, manned space stations. Information con- cer.ning the earr.t's surface can be obtained from these flight vehicles as - a result of visual observations, in the form of television images, photo- graphs of the earth and data from photoelec:tronic apparatus. We will examine different types of aerial and space surveys. Types of Aerial Photographic Surveys of the Earth's SL:rface An aerial ghotographic survey is a method for photographing of the earth's surface by an aerial camera which is mounted on an aircraft, helicopter or other flight vehicle. The choice of equipment and instrumentation for carrying out an aerial sur- vey of the soil cover is of great importance for obtaining spectrograms and aerial photographs with the best possibilities for interpretation. During recent years in our country IL-14 aircraft, specially re-equipped for the placement of aerial cameras, and -,ist recently, also the AN-30, have been used for photographing the earth's surface. Modern aerial cameras are classified on the basis of focal length, angle of �view or objective and number of objectives. On the basis of focal length aerial cameras can be classified as short-toGus (f to 150 mm), mediimm-focus (f from 150 to 300 mm) and long-focus (f above 300 mm). Short- and medium- focus (focal length) objectives have assumed the greatest importance for soil surv2ys, carrying aut land surveying and for mapping purposes. In low- lands and slightly hilly territories it is desirable to use aerial cam- eras with a short focal length (50-100 mm). Suvpr-wide-angle aerial cam- eras (50-70 mm) ca.n give the best results in steppe and dry steppe zones in the territories of the plains bordering on the Black Sea, Sea of Azov and Caspi.an Sea, as well as in the lowland e-.tpanses of Kazakhstan with well-developed mi:.rorelief. Aerial cameras with a medium focal length (200 rnm) should be used in mountainous and highly dissected territories with local relief of nore than 150-200 m. In a suFer-small-scale photographic survey (1:100,000-1:250,000) a compar- ative analysis of different types of aerial cameras with a short focal length indicated that for an aerial survey of different territories it is possible to recommend the TES-50 and 41/7.5 aerial cameras with focal lengths of 50 and 75 mm (Apostolov, Gorbatov, 1975). _ In making a large-scale aerial photographic survey (about 1:10,000) it is reconmended that use be made of an AN-2 aircraft ani an AFA-39 aerial - camera.with a focal length of 100 mm. It is simple to service, is reliable - in operation and makes it possible to obtain photographs with a high in- formation content. 15 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 ~ FOR OFFICIAL USE ONLY - Table 1.

During reeent years there has been a particular increase in the role of multiobjective aerial cameras employed in a multizonal survey in a study of natural resources, soil cover and the state of agricultural crops. A set of light filters was used in carrying out a multizonal photographic survey in 1973a Data on some of these are given in Table 4. The materials obtained in this survey were used in our study. The broad array of aerial survey photographic and photoelectronic appar- atus carried aboard aircraft enables specialists in the field of study of the soil cover and agricultural crops to use materials from an aerial suir- vey not onlq for the purposes of mapping, but also for study of the makeup of the compositton and properties of soil$ and determining their fertility. These data make possible an approach to automation of the process o* j.nterpretation of the soil cover and agricultural crops-with use of an el- ectronic computer. In additiony the methodology used in a number of exper- iments carried out with aircraft is used wh,an carrying out space invest- igations.

A. Gagarin. G. S. Titov �or the first time in histo ry carried out a survey of individual natural features by camera. Visual ob servations from space were also made by other costnonauts. = A great number of original photographs of the earth's surface was obtained in the U SSR and in the United States as a result of flights of spaceships and artificial earth satellites. Black-and-white, color, and spectrozonal photographs at scales 1:200,000-1:2,500,000 and smaller have a clear image of the so il cover and agricultural fields. The images of the earth obtained from space can be divided into two main groups~ o riginal space photographs and television images. The original photographs are characterized by high measurement and interpretation prop- - erties. In compariGon with space photographs, a televisian survey has ad- : vantages with respect to frequency, repetition and regularity of collec- tion of images of the earth's surface. However, television photographs are - characterized by a lesser resolution. In the Soviet Union photographing of the earth's surface from space, with the obtaining of original space photographs, was accomplished using hand cameras and photographic apparatus from the sutomatic stations "Zond-5," "Zond-7" and "Zond-8," the "Vostok," "Voskhod" and "Soyuz" spaceships and the "Saly uC" orbital station. Photographing of the earth was carried out during flight of the "Voskhod-2" ship-satellite in 1965 during the emer- gence of A. A. Leonov into space. During 1968 the "Zond-5" automatic station was used in obtaining the first _ global photographs of the earth from an altitude of about 90,000 km. 20 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 , FOR OFFICIAL USE ONLI' ~ a~ r c~d ~ w a~ 4J r1 ~ ~ x C.) ~ ~--I ~ W O CJ ~i 4.1 ~ ri ~ d 41 v c~ ~ c~ ~i u ~ ~ H 00 O 41 O ~ a ~ I I S � 8 S 8 ~ R ~ 8 Cf 10 u � ~ ~ O O p O p 00 ~ tD tp ~ (p O tD to ~ p pp ~ p ~ ~ t~ %T a - ~ a0 V V t- ~ V t0 a0 a S N ~ V) a o J-~ ^ M GV O N CD tA Cd ~ N N N GV CV C'1 N CV tD I 0 .0 . ~ . r.

V. Khrunov and A. S. Yeliseyev emerged into open . space and carried out visual observations, still and motian picture aur- - veys of the earch'a surface. In accordance with the program, during the - group flight of the "Soyuz-6," "Soyuz-7" and "Soyuz-8" manned spaceships ~ observations were made and phoCographs were taken of the soi.l-vegetation cover and the nature of the geologica:t-geographic features in different regions of the USSR. - A space survey was made for territories well studied in natural respects . for the purpose of developing a method for using space photographs for studying the earth's natural resources. Another important aspect of the program was a study of the specCral brightness and contrasts of the earth's surface in the visible zone of the spectrum (steppe, desert, forested areas, lakes), necessary for determining the optimum conditions for the nhotographing of natural features. As indicatsd by K. Ya. Kondrat'yev, et al. (1971), tiy ha.ving spectra of natural features obtained irom space it is possible to differentiate types of soiZs, determine the state of ag- ricultural crops and solve other problems. - In mid-June 1970 the cosmonauts V. I. Sevast'yanov and A. G. Nikolayev flew aboard the "Soyuz-9" spaceship. During the flight they made observa- tions of agricultural fields and the soil cover over the territory of the Sal'sko-Tsimlyanskiy and other regiona of the USSR. In accordance with the program, they carried out photographing of the earth's surface in the Northern Caucasus, in the neighborhood of the Caspian and Ara1 Seas, Kazakhstan and Western Siberia. Simultaneously with the survey from = space, these same features were photographed �rom aircraft (Sevast'yanov, 1972). The cosmonauts were able to discriminate sown areas with respect ~ to the variety of agricultural crops and the phenological stage of,devel- opment. The survey from the "Soyuz-9" was made using a yellow light fil- ter on sma11-format panchromatic film using a hand camera with the frame measuring 6 x 6 cm from an altitude of about 230 1m at a scale of about 1:7,500,000, with a resolution of 200-300 m in the terrain. _ The long-lived orbital station "Salyut-1" was l4unched in 1971. It was a _ complex manned space vehicZe making it possible to carry out a broad com- plex of scientific experiments in circumterrestrial sgace. The station was launched into orbit at an altitude of 240-260 km with an inclination - of 51.6� to tYie equatorial plane and urith a period of revolution about the = earth of 89 minutes. - After the docking of the "Salyut-1" with the "Soyuz-11" spaceship the crew _ carried out a spectral survey of characteristic features on the earth's surface. At the same time, an aer.ial survey was made of these same regions from specially outfitted aircraft of an expedition of Leningrad State Uni- versity and the USSR Academy of Sciences. During this space flight for the ' firsc time there was a continuous reconnaissance photographic survey along global trajectories running along and across the earth's latitudinal phys- - iographic zones. The survey was made in June with an AFA-�;;ls aerial camera 22 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OrFICIAL USE ONLY without a light F:LLter w1.th a focal length of 31.6 mm (frame measuring 60 x 70 mm). The photographs were taken us.ing isopanchromatic film type 17. The 5cale of the photographs was ataout 1:8,000,000 with a-resolution in the terrain of 250-300 m. The area covered by one photograph is abouC. 250 kmZ. `Phege phoeo};r.aphs, due to their great coverage, are of grPat iinpor- tance for smal]-scale special mapping. _ '1'lie beginning of a multizonal survey of the ear.th's surface from space is assnctared with the Flights of the manned spaceships "Soyuz-12" and _ _ "Soyuz-13" in 1973-1974. The survey was made using the special LKSA,-3 9-abjective camera in wtiich three photof ilms were used simultaneously. _ Further visual observations and photographing of the earth's surFace for the purpose of xational use of terrestrial resources in the inh.erests of the nattona:l economy wer.e carried out during subsequent tlights of space- : ships, the orbital station "Salyut-3," launched in June 1974, anci during ' the "Soyuz-Apollo" joint flight. Much experimental photographic material from space, necessaZy for study of - the earth's natural resources, was obtained as a result of the "Salyut-4" flight. I'hotograptis for a considerable area were obtained for the terri- - tory of aur r_ountxya pr.imarily in ttie middle and sourhern latitudes. Spec- _ trographic measurements of individual geological-geomorgiiological forma- tions on the earth�s surface were made. The "Salyut-5" wcs launched in 1976, and for joint er.periments with it, rhe "Soyuz-21." ` Ttie iiew qualitative characteristics of phorogrophy of the earth's surface f rom space by means of lonp-term orbital stations of the "Salyut" type are as Eollows: 1) Lhe possibility of carrying out a great volume of photo- grapliy with coverage of different survey seasons; 2) regeated surveying of _ - one and the same natural features; 3) use of different cameras and diffe. - - - ent f.ilms, making it possible to carry out a survey at different scalES - - and hn d:l.fferent spectral zones; 4) choice of the optimum atmospheric conclir:.ion:; for a space survey.

In 1978, during the flight. of the "Salyut-6" - orbital station, a multizonal survey of the earth was continued using the MKF-6rt camera. In addition to direct photographing of the earth from space, another impor- tant direction which is new experiencing vigorous growth and development is a televislon space survey.

S1nce the time television systems is 1/25 sec or less, and is 200-400 sec, the need arises for using aboard the satellite. It is also possible to systems ar2 known as phototelevision systems. In comparison with photographs from space, television photographs have a lesser resolution (from 80-1.00 m to several kilometers); their metric prop- erties are also poorer due to the nonlinearity of scanning, etc. 14hereas at the presEnt time in the actual study of the earth's natural resources - from space photomethods, with the best resolution, play an important role, in the l.ong rtin scanning systems with the transmission of ir,formation from satellites via radio channels will have ever-greater impor ance. The role of scanning systems will increase still more if it is take., into account that in a photographic survey of the earth's surface the deliveries of materials to the earth are considerably less routine. Precisely the rou- tineness of r_ollection of information on the state of terrestrial re- sources is one of the basic and fundamental characteristics of a survey from space. In our counrr.y a television survey for national economic purposes is also - made Froin meteorological satellites, which ma.kes it possible to obtain rou- - " tine informarion on the state of weather on the earth and the characteris- tics of the underlying surface. Satelli.tes of the "Cosmos" series were used in 1963 in testing the corres- ponding television systems and electrotechnical deviczs. In 1966 rhe "Mol- niya-1" satel_lite was used in the USSR for obtaining a TV image of the earth from a distance of 40,000 km. Later dt!ring flight of one of the sat- e I I i t.t-:; of the "Cosmos" series photographs wzre taken of the cloud cover rzncl the underlying surface in the infrared in the spectral range 8-12 Nt.m. in 1967 lrtificial ear.tli satetlites of the "Cosmos" series were launched for EorminR the unified "Meteor" space system. The satellites were put in- to circular orbits wirh an altitude of 625-630 km. During 1977-1979 rou- tinc: information on the state of the earth's surface was regularly trans- mitted from experimental "Meteor" satellites in four zones of the visible - and infrared spectral ranges. _ In the United States flights of ttiel"Mercury" (1961-1963), "Gemini." (1964- 1966) and "Apollo" (1968-1971) spaceships made it possible to obtain hun- dreds of space photographs of different regions on the earth.(most of the photographs were color photographs). The survey was made with hand small- - format cameras. Since 1960 television images oi the earth` s surface have been regular?_y traiismitted from American meteorological satellites. The first eight sat- ell-s of the "TIROS" series were launcheA in 1960-1965. 24 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007102/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USL� ONLY Satellttes of the ITOS series (ITOS Improved TIROS) were laiinched in 1970 into a solar-synchronoiis polar orbit with an altitude of about 1,400 km (wtth a period of revolution 115 minutes).'Phey carr i.ecl 'I'V c,uneras for tranamission of images of the earth at a real time scale (with a reso- lution of ahout 1 km) and in the record (resolution 3.2 km). The United 5tates meteorological satellite, whic'i is of interest because its materials can be used in interpretiny , the ear*_h's surface, is the _ "Nimbus." The latest-satellites of the "Plimbus" series carry a microwave probe fo r determining soil moisture content. - The first specialized satellite for studying the earth's natural resources (ERTS-.L Garth Resources Technological Satellite) was launched in July 1972 in the United States. The ERTS-2 was launched in January 1975. These = satellites have now been given the name "Landsat." A third satellite was - launched in 1978. The satellites were put into a solar synchronous orbit with an altitude of about 910 km with a period of revolution of 103 min- - utes. The selected orbit ensures an almost constant solar altitude above the horizon N 35�, that is, identical illumination conditions for each re- gion. The satellites make 14 revolutions per day and each 18 days there . is a possibility for a repeated survey of one and L-he same sectors r,f the earth's surface. The 1iRTS-2 was launched in such a way that the frequency of recurrence of , a survey of one and the same sector of the earth was 9 days, whj.ch made - it possible to observe the dynamics of the soil-vegetation cover and the development of agricultural crops, to study the sotl-vegetat:ton cover in different seasons of the year, to select cloudless periods oF the survey in order to have a better image of the soil-vegetation cover in dependence _ on weather and seasonal conditions of the survey, etc. The satellite carr- - ied a multichannel oPtic.al-mechanical scanning television camera, tlze MSS (Mult1. Spectral Scanner), an instrument scanning in the visible and IR spec- tral r.egions: 0.5--0,6, 0.6-0.7, 0.7-0,8, 0.8-1.1 V-m. The camera angle of view is 11.5�; in scanning from an altitude of 910 km there is coverage of a zone with a width of 185 km and the resolution in the terrain is 70- 80 m. Photographs with the MSS multizonal scanner are of interest for diff erent branches and departments and are effective when using such automatic sat- ellites for studying the earthTS natural resources. ~ In May 1973 l-he "Skylab" orbital station was launched into an orbit close to circular, with an altitude of 435 km and a period of revolution of 93 minutes. One of the scientific objectives of operation of this station was an investigation of the earth's natural resources. Thus, artificial earth satellites, spaceships and orbital stations are used for studying the earth's natural resources. Special automated satellites for studying the earth's resources have been developed and used in recent years. Photographic and television cameras are among the instruments , 25 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 - widely tised on space vehicles. Both space multizonal photography and multi- spectral scanning of the earth's surface from space are successfully devel- _ opinR. Infrar-ed and microwave apparatus is also used in space surveys. The altitudes for a space survey of t}le earth's surface can be divided into - four grouPs: 1) great altitudes 10,000-100,000 km surveys from interplanetary sutomatic stations of the "Zond" type; 2) medium altitudes 500-1,500 km surveys from natural resources and meteorological satellites; 3) low altitudes 200-400 km surveys from manned spaceships of the "Soyuz" type, long-lived orbital stations of the "Salyut" and "Skylab" type, and experimental satell.ites; 4) very low altitudes less than 200 km surveys from experimental sat- - ellites. Witli respect to the area of coverage of the soil cover by a single space photograph we propose that photographs be classified as: a) global transmission of the image of individual continents or the earth as a whole (for example, photographs of the earth from the automat- ic station "Zond-511); b) macroregional'-- images of major parts of the continents with an area - of 1.00,000 km2 or rnore (photographs from NOAA, and others); c) mesoregional with coverage of geographic regions with an area of tens _ of thousands of square kilometers, for example, the multizonal survey with _ the MKP'-6 camera from the "Soyuz-22" and the "Salyut-6" from an altitude of 250-260 km in six spectral zones (from 0.46 to 0.89~tm) with an area of coverage of one photograph of 19,000 km2; a multispectral scanning sur- vey with the MSS camera from the ERTS ("Landsat") from an altitude of 310 km in four spectral zones (0.5-0.6, 0.6-0.7, 0.7-0.8, 0.8-1.111m) with an area of coverage of one photograph of 35,000 km2; d) regional with a coverage of individual regions (landscapes) with an _ area less than 1,000 km2. - Depending on the survey scale space photographs can be classified as large- ' medium-scale (greater than 1:100,000), medium-scale (1:100,000-1;900,000), small-scale (1:1,000,000-1:9,000,000); generalized (1:10,000,000 - 1:100,000,000).

It is possible to use blaak~and-white, color and spectrozonal negatives, double negatives and double positives obtained in.the course of aerial and space surveys; black-and-white, color and spectrozonal aerial and space photographs obtained by the contact method or by enlargement on the average by 4x-5X; reproductions of preliminary compilations, photomosaics, photoplans and photomaps. During recent years increasing importance has been assumed by aerial and space materials from a multizonal survey, tele- vision photographs, materials from multispectral scanning systems, traces ohtained from ultraviolet, infrared and microwave radiometers, and radar photographs of the soil cover and plantings of agricultural crops. In this sect:ion we will examine the importance of materials obtained using _ photographic systems; others wiZl be examined in describing new photoelec- tronic methods for investigating terrestrial resources. ~ Black-and-white, color, spectrozonal and multizonal negatives and double r - positives are of great importance in studying the soil cover and the con- _ dition of agricultural crops. Their role has especially increased in con- - nection with the use of multizonal surveys of the earth's surface. The principal photographic characteristics of black-and-white aerial films are giv'en in Table 5. A black-and-white panchromatic film and a yellow light filter were suc- cessfully used in surveys from the "Soyuz-9" spaceship. In surveys from the "Salyut-1" orbital statidn successful photography was carried out - using arL isopanchromatic film (type 18) with a yellow light filter. ~ Wben making a multizonal survey from the "Soyuz-12" spaceship the photQ- graphy was with different light filters on fine-grained isopanchromatic aerial film (type 17), coarse-grained isopanc:izromatic ffiotion picture neg- ative film KN-3 and coarse-grained infrachrb:n:itic aerial film 1-840. _ In multizonal photography of desert and semidesert zones of Kazakhstan in February from the "Salyut-4" orbital station use was made of black-and- - white films: isochromatic of the type AS-1, isopanchromatic of type 17 - and infrachromatic of type I-840.

In the United States, when carrying out a multizonal survey from the "Ap- 0ll0-9" spaceship, the photography of the earth's surface was taken on panchromatic and infrachromatic film. During the period of operat?on of the "Skylab" orbital station black-and-white panchromatic film was used in two surveying cameras of the multispectral photographic apparatus S 190, whereas infrachromatic film was used in two others covering the infrared spectral zone. WYen making a super-small-scale aerial survey of the earth's surface Apo- _ stolov ar_d Gorbatov (1975) recommend the use of black-and-white films: _ for lowland regions types 17, 18, 20, 27, 28, for mountainous regions types 17, 20, 25, 33. Isoorthocrromatic black-and-white aeriai films of the RF-3 and AS-1 types are recommended for aerial surveying in the yellow-green spectral zone. - In addition to isopanchromatic films, the infrachromatic films I-740, I-760 and I-840 are af great importance for studying the soil cover. A comparative analysis of the soil cover image on aerial photographs taken - with isopanchromatic and infrachromatic films indicated (Fig. 1) that on infrachromatic photographs it is considerably essier to see the boundary contrast of chernozem and alluvial soils; dark gray, gray forest and soddy- meadow soils. On isopanchromatic photographs these soil differences are seen poorly or not at all (Table 7). The use of infrachromatic film for soil purposes can be recommended for the detection of soils with a different degree of moisture content, gley- ey, swampy, irrigated soils. This film is effectively used for discrimin- ating plowed sectors amidst virgin land with natural vegetation, for the interpretation uf areas of alluvial (floodplain) soils. However, when using infrachromatic film it must be remembered that in com- parison with isopar_chromatic film there is a deterioration of image devel- opment in shaded sectors. In order to reduce the influence of shadows it . is desirable that the infrachromatic survey be made at about 1200 houzs with a high solar altitude. - B. V. Vinogradov (1966) mentions the limited possibilities of use of this fiim in studying the soil-vegetation cover of arid zones. in a survey wict: this film the dry sectors of brown desert-steppe soils, solonetz and - other soils merge with vegetation oiz the photoimageo ~ 28 - FOR OFFICIAL USE ONLY .

Color revsrsible three-layer aerial films for neutral and transfo rmed color transmission of the earth's surface are widely used abroad. Modern color films, both in our country and abroad have a quite high sen- sitivity, low distortion, good color balance and resalution (Table 8). They can be used successfully not only for a qualitative, but also quan- titative interpretation of the soil cover and plantings of agricultural crops but are inferior to black-and-white aerial films with respect to the economy of photoprinting. TsN-3 color negative film is an improved TsN-1 type with respect to color transmission, with a higher resolution and light sensitivity. Th is is a three-layer fi1m; the arrangement of its layers, the type of sens itizing of the emulsion and the spectral zones of effective light sensitivity are indicated in Table 9. Good results were obtained in the USSR in a survey from space us ing SN-6M and SN-8 spectrozonal. films (zones of sensitivity 570-650 and 650-800 nm j respectively). A somewhat worse image of the earth's surface was obtai.ned in a space survey on TsN-3 color film (zone of sensitivity 450-730 nm) with natural color transmission. Color natural film of the Kodak Ectachrom MS type and color IR Kodak-Ecta- _ chrom Infrared film was used during flights in the American spaceships " "Mercury," "Gemini" and "Apollo" for extensive survey work. In the irrigated zone of the Colorado River (United States) colo r IR film was also successfully used in discriminating agricultural fields up to 20 hectares in area, eccupied by different crops, from the red and.gray- green color. A red color was characteristic of fields with alfalfa and a gray-green color is charactsristic of fields with harvested co tton. In a mountainous area a brown-red color corresponded to coniferous forests (Pinus ponderosa) and a light red color corresponded to oak forests. In the study of soils with different moisture content (from 2-8 to 30-34%) it was established that the best results in determining the mois ture con- tent of plowed soils were obtained in an aerial survey from an altitude ; of 600-1,200 m on color IR film (Sewell, Parks, 1972). The use of negatives and photometric instruments makes it possible to carry out quantitative measurements of the photoimage of the soil cover, based on determination of the density of blackening of the analy zed nega- tives. It is now acknowledged that the photometric approach to the study ~ of soils from negatives is one of the promising means for autamation of ~ - 34 FOR OFFICIAL USE ONLY ~ APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY' interpretation of the soil cover. The basic studies on use of photometric instruments are now being made using black-and-white negatives. However, there are investigations of the use of color and spectrozonal images for these purposes. B1ack-and-white, color, spectrozonal and multizonal contact or enlarged _ aerial and space photographs are of basic imgortance for visual-instruren- tal interpretation of the soil cover and its mapping. In accordance with the type of aerial survey cameras usPd the common size - of aerial photographs is 18 x 18 cm; 24 x 24 cm; 30 x 30 cm; for multi- _ zonal cameras it is 7 x 7 cm. The photographs taken by a multispectral scanning system can have the form of strips. In our country a size 18 x ~ 18 cm is used for measurement and cartographic purposes and the principal photograumetric instruments have been developed for this size; abroad a size 24 x 24 cm is used for this purpose. Aerial photographs measuring 30 x 30 cm are convenient for interpretation of the soil cover. - A considerahle economic effect can be obtained when using photographs en- larged by 3-4X in comparison with the original. According to data publish- ed hy American specialists, a photographic enlargement of the space photo- graphs obtained with the.ERTS for the purpose of facilitating their soil interpretation and increasing the information yie13 is dependent on the negative quality and after a SX enlargement gives virtually no increase in information. The scale of the photographs is determined using the formula 1/m = f/H, where f is the focal length of the objective, H is survey altitude. Near-vertical aerial photographs have a normal end lap of 60% and a side lap of 40%, wnich ensures inspection of stereopairs with stereoscopic in- struments. Aerial ar space photographs are of importnnce for soil mapping - hecause they are a good geographic base. The great number of details appe4ring on aerial photographs make possible a more precise identifica- - tion of the location of soil profiles and orientation in the terrain. Aerial or space photographs constitute completely objective material on - natural conditions and the soil cover, which is obtained using photo- � _ graphic or phototelevision instruments. It is particularly important that on aerial and space photographs there are a number of direct and indirect indicators necessary in interpreta- _ tion of the soil cover. This property makes it possible to carry out the office interpretation of soils and with the development of knowledge concerning the image of different soils on photographs and the develogment of soil keys it is possible to reduce the time-consuming field work for study of the soil cover gradually to a minimum. The reproduction of a preliminary compilation is a mandatory supplement to aerial photographs. These are prepared from aerial photographs (con- tact prints) and make it possible to draw conclusions concerning 35 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 the correctness with which the aerial survey was made.

This information makes pos- sible a rapid determination of the region and the numbers of Che aerial pho- - tographs required for the work. - Photomontages are an assembly of unrectified aerial and space photographs - (thar is, the use of photographs without elimination of existing distor- - tions). A photoplan is a plan of the terrain (mosaiced montage), assembled from rec- tified aerial and space photographs. It has a coordinate grido On photoplans the relief is frequently drawn in with contour lines. According3.y, photo- plans are valuable material for studying the soil cover and its mapping. We note that when photoplans are available there is no need for photomon- tages. - Photomaps (black-and-white and color) are the most valuable base for carry- - _ ing out soil mapping. They conatitute polygraphically reproc:ucible photo- _ - plans on which contour lines are used in plotting local relief, whereas ' hachures are used for representation of the topographic necessary for the soil survey. In comparison with topographic maps photomaps provide a sav- ~ ing, according to preliminary computations, up to 15% of the cost of work - on a specialized survey (Gol'dman, 1972). Instruments for interpreting soils and agricultural crops. The visual.-in- strumental method for the study of photographs is the most promising for soil interpretation. It provides for the extensive use of photometric and photogrammetric measurement instruments under field and office conditions. - Depending on their purpose, interpretation instruments can be classified as , enlargement, measurement, stereoscopic, micropho tome tric and automatic - systems for readout of the image. 34.-_ Among the magnification instriunents extensively used in the soil inter- pretation process are monocular lenses with different magnifications. - Those with 2X and 4X are most widely used. The measurement instruments include parallaxometers, parallactic plates, proportional dividers, etc. In the mapping of soils the use of proportional - dividers is of great importance for eliminating a noncorrespondence of scales (between the photograph and map) in the transfer of special content from the interpreted photographs onto topographic maps or land surveying plans. Among the measurement instrimments used in the interpretatian of the soil cover an important role is played by MF-4 and IFO-451 microphoto- meters and among the foreign instruments a high-speed microphotometer with a contiguous stand and a compensation automatic recorder produced by "Karl Zeiss" in the GDR and others. The use of these instruments for meas- uring optical densities of aerial photograph negatives makes it possible 36 - FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-00850R040340050024-7 FOR OFFICIAL USE ONLY to ascertain the nature and indi,vidual preperties o� soila in the analyzed territary.

Among the processing instruments neceasary for the computerized interpret- ~ ation of multizonal photographs we no'ce the "Y-1700" ".'Photomachine" devel- oped by "Optronics International" in the United States, making it pos- ~ sible to carry out rectif.ication of the photographic image and construct maps of isodensi..ty lines for the forest and soil cover and f.or agricul- tural crops (Sukhikh, E1'man, Bogachev, 1978). The ISI electronic systera (International System Incorporated) makes it possible to carry out rectification on the basis of densities for both integral and a series of multizonal aerial and space phozographs.

In both English : and Russian the corresponding term is "interpretation." During recent ~ = years the corresponding Russian tenn "interpretatsiya" has been used ae a synonym for "deshifrirovaniye." Originally interpretation was carried out for, military-topographic pur- poses. However, beginning in the 1920's, with the development of civil aerial surveying, the interpretation of aerial photographs began to ac- quire a special character. In addition to topographic interpretation, forest, geological, soil, geobotanical, hydrological, agricultural and - other types of special interpretation of aerial photographs began to de- _ velop. At the present time the soil cover is being interpreted from space photographs. By the term "soil int_erpretation" is meant the method for studying the soil cover from its image obtainecl as a result of aerial or space sur- - veys. At the very dawn of development of aerial surveying A. Ye. Fersman wrote that an aerial survey does not characterize any one phenomenon, but dif- ferent aspects of the landscape. It puts into the hands of the researcher - a dialectic method which in the study of each feature makPs possible a determination of its relationships to others. In this respect a study of the Qoil cuver from aerial or space photographs ia a clear example of use of the dialectic method. Pt. G. Kell' emphasized that the interpretation of aerial photographs is a multifaceted process and no facet of this proceas can be separated from - th4c branch of research in which it is manifested (Kudritskiy, 1973). 38 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY , L. A. Bogomolov (1976), L. M. Gol'dman (1960), G. V. Gospodinov (1961) and L. Ye. Smirnov (1976) define interpretation as a method for studying terrain from its image on photographs, as a process for revealing the diverse content of photographs, based on an anal,ysis of the interpreta- tion criteria and a knowledge of their properties. " General Principles of Soil Interpretation The interpretation process, from the point of view of knowledge and logic can be subdivided into a number of basic stages. I. S. Komarov, V. F. Rubakhin, L. T. Safronov (1967) indicate that with respect to structure the interpretation process consists of interpretation of individual fea- tures from aerial photographs and interpretation of situations. Three - stages can be discriminated in interpretation: detection, identification and evaluation. A number of researchers call the third stage "interpreta- tion ; however if the feature does not show up on the aerial photograph the interprptation process begins with identification. L. Ye. Smirnov _ (1967) defines the third stage of interpretation as the forming of judg- - ments concerning individual features, phenomena and the terrain as a whole. V. F. Rubakhin (1966) ends the third stage in an evaluation of the results of identification of individual features and as an independent final section discriminates the process of real intarpretation of situa- tions.from the aerial photograph, that is, there is a transition from the - identif ication of one feature to another, from the identification of simple features to complex ones. L. M. Gol'dman, R. I. Vol'pe (1968) also divide the interpretation process, on the hasis of psychophysiological principles, into three stages: 1) vis- ual perception of the studied features; 2) formulation of concepts (taking into account the conditions for carrying out the aerial survey) concerning , the investigated territory and 3) a conclusion and description of the es- _ sence of the interpreted features. A number of foreign authors (Buringh, 1960; Vink, 1968) include the fol- lowing under the term photointerpretation: 1) recognition and identifica- - tion of features appearing on phatographs; 2) their anaZysis; 3) deduction, whose role is limited and can be used in the extrapolation and intergola- tion of data. - According to Buringh (1960), the terms recognition and identification take -in obtaining the most complete and clearest idea possible from the photo- graph. Some foreign authors use the term photoreading instead of identif- ication. M. Girard (1972), in examining the problems involved in the soil interpret- , ation method, discriminates three stages: 1) identification, that is, de- termining the relationships between the feature and its image on the photograph; this correspondence is not always expressed clearly for soils; 2) recognition, which essentially involves drawing of conclusions concern- ing the soil cover on the basis of knowledge concerning the morphology of 39 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 soils and the peculiarities of their formation; 3) interpretation pro- vides for estahlishing the interrelationships between soils and soil- forming factors. In the interpretation of features, including, the soil cover, it is neces- sary to take into account the initial level of interpretation. It is depen- denr on the level of training and capabilities of the interpreter and also the availability or nonavailability of interpretation keys. A. P. A. Vink (1968) points out that the term identification or photoread- - ing must be defined as a method for studying the aerial photographic image, which is based on a direct study of the features. The soil, as a natural feature having a definite structure of the genetic profile and difftrent soil horizons,.does not show up on aerial photo- graphs. On such photographs we see indices oniy of the surface horizon. However, this main surf.ace horizon is genetically related to the e;itire soil profile. Accordingly, by analyzing the image of the surface horizon on aerial and space photographs in most cases it is possible not only to determine and interpret soi: boundaries and changes, but also (in field - investigations when samples are available soil interpretation keys or soil maps) to determine the soil cover. ~ According to B. B. Polynov, all soil horizons are paragenetic, that is, _ inCerrelated in their origin. On this basis, asserts Yu. A. Liverovskiy, (1962), the properties of the upper horizon can serve as indicators for determining the genetic category for the entire soil. The relationship of tb,e volume of field and office interpretation is of considerablE importance in this stage of development of the soil inter- pretation method. Whereas during the first period of study of the soil cover with the use of material from an aerial photagraphic survey the - role of field interpretation was fundamental, with the development of aerial methods, with the use of new equipment, with the broadening of - knowledge concerning the peculiarities of the photoimage of soils on different films and for different s2asons of the year, with the develop- ment of soil interpretation keys and with use of multizonal photographs - there is a marked increase in the role of preliminary office interpreta- tion of soils. Without question, in the future with the development and improvement of aerospace (remote) methods for investigating the environ- ment the role of office interpretation will increase to the point of automated computer analysis of the soil cover and plantings of agricul- cural crops on the basis of aerospace photographs and trace data (when soil-agricultural interpretation samples are available). During recent years three principal methods have stood out clearly in the problem of interpretation of photographs (Zonn, 1975). The first method, pr,: -iiltng broadly until recently, is the visual interpretation methoda The essence of this method is that recognition of the soil cover is based = 40 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY on experience and the ability of specialists to use direct and indirect criteria for soil interpretation. Its shortcoming is the descriptive ap- proach to soil and agricultural resources and a definite subjectivity. _ At the present time it is being replaced by the visual-instrumental method, _ in which, on the one hand, there is the most complete use of the logical inferences of the interpreter, and on the other hand, a quantitative anal- ysis of the photoimage and interpretation of the soil cover. Visual-in- strumental interpretation as an objective quantitative method for study ~ of aerial and space photagraphs is based on the broad use of such meas- urement instruments in the practice of soil and agricultural research as microphotometers, densitometers and optical-electronic image analyzers. A third method, which is in the stage of initia:t experimental investigation, is related to automation of the process of interpretation of photographs. It provides for the transformation of the photoimage of t,he soil cover and agricultural fields and the statistical processing of the filtered images. For example, in a soil melioration description of the territory of the dry steppe zorie use was made of optical-structural machine analysis, which is a method for generatized (statistical) analysis of the morphological structure of the feature carried out in the optical range (Kozlovskiy, et - al., 1975). Digital methods in the processing of aerial and space informa- = tion are being developed most intensively in the Soviet Union and in the United States. They provide for the development of equipment, input of data on the image into an electronic computer, methods for its storage and extraction and creation of mathematical support for the processing of in- formation (Lur'ye, Tishchenko, 1966). In a report at the Eighth International Mapping Conference (Bel'chanski.y, et al.,.t976) it was pointed out that three problems are time1y among the principal directions in the development of inethods for the digital auto- mated processing of images: 1) processing and formalization of videoin- , forn,ation; 2) automation of interpretation of photographs with the use of an electronic computer or optical-electronic instruments; 3) formulation of mathematical models in the plotting of predictive maps. A. Rozenfel'd (1972) discriminates five types of image transformation: discretization, quantization, coding, approximation and filtration. As - indicated by L. A. Bogomolov (1976), all these transformations can be used in automation of the process of interpretation of aerial and space photographs. However, automatic interpretation simplifies and to a defin- - ite degree distorts the informa.tion on the photograph. It is done inde- pendently of the environment and without reference to existing natural interrelationships. As indicated by discussion of these matters at inter- - national and national symposia, success in the automation of interpreta- - tion at this stage for the time being can be expected in the solution of special problems and in narrowly specialized fields of investigation. 41 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 ' The tasks oL soil interpretation can be formulated in the following way: first, detection and outlining on aerospace photographs of terrttories with an identical structure of tlie soil cover, which must be defined as unit soil interpretation; second, determination of the content of the soil units detected on the photographs genetic soil interpretation; an important independent task is the extrapolation of the results obtain- ed for individual points (profiles) or key sectors on the basis of visual- instrumental or instrumental (automated) interpretation of the soil cover. . The specific nature of the soil as a feature to be interpreted also deter- mines the content of the process of analysis of the photomaterials (Vink, 1968, and others). It includes all aspects of their identification or - photoreading and also the digital evaluation, determining the mutual re- - lationship of the photoindicators detected ii; the interpretation. The _ analysis involves carrying out work for study o! the individual components - of the environment and their interrelationships to the soil cover. Yu. A. Liverovskiy (1962) mentions the need for using physiographic synthesis as n basis for soil interpretation. Its importance increases sharply in space investigations. A specific property of use of space photographs in soil science is that in their interpretation (due to the great coverage of considerabie ter- ritories) there is a marked increase in the role of indirect interpreta- tion criteria, the geographic method for the study of space photographs and allowance for interrelationships and intercausalities of all environ- mental components. _ In tr.e study of soils from aerial and space photographs as a point of de- parture one must apply the principle expressed by V. V. Dokuchayev that the soil is part of the geographic landscape, is its "mirror." Soils and - such factors of soil formation as relief and vegetation are refiected on - photographs in a reduced generalized form. In this connection the inter- - pretation of soils is essentially based on a comparative geographic anal- ysis of the photoimage of na.tural or man-modified landscapes. On the basis of the principles fo-rmulated by B. B. Polynov relative to - elementary landscapes and types of terrain, the use of photographs makes it possible to determine interpretation criteria characterizing the safls - of these landscapes. In formulating the principles for soil interpreta- - tion from photographs we used as a point of departure interpretation, on _ the one hand, of soils of natural landscapes, and on the other soils - of cultivated (plowed) elementary landscapes. The interpretation of soils and agricultural objects can be improved (es- _ pecially in multizonal aerial and space surveys) if we know the charac- teristics of their reflectivity in a definite spectral zone and carry out a siirvey in those narrow ranges where the spectral differences between - soiis ar.d planted crops are maximun. These matters will be considered below. 42 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY Spectral Reflectivity of Soils Multizonal brightness of objects and features, including soils and agri- cultural crops, is a new and important interpretation criterion which makes it possible to carry out quantitative measurement of soils and agricultural fields on the basis of their image on photographs. With the - use of scanning systems the digital processing of mu].tispectral photographs can proceed until an image is obtained. For example, for studying the soils of the northeastern part of Kansas use was made of reaterials from a multi- spectral scanner having 15 spectral ranges in the zone 0.4-0.9~J.m. The re- _ sults of the scanning were registered directly on a magnetic tape which could be processed on an electronic computer. At the same time, a survey was made on 70-mm color and color IR film. In computer processing use was - made of the differences in the spectral reflectivity of the soils (greatest in the near-IR spectral zone), which were registered hy a scanner. In each of the sectors of the electromagnetic spectrum there are differences in _ the spectral brightness of the soils and therefore in working in each = range use was made of the mean values of spectral reflectivity of soils (Carroll, 1973). = The use of the photoimage of one and the same objects, obtained simultan- eously in different spectral zones, makes it possible to obtain addition- al information on soils and agricultural crops. It can be seen from a com- . parison of two aerial phutographs of one of the experimental sectors in. the steppe zone during spring in such a survey, taken in the red (640 nm) _ and orange-yellow (590 nm) spectral zor,es,that in the zone 640 nm there - is reliable discrimination of typical chernozems from meaclow-chernozem soils associated with depressions and also chernozems with different de- grees of erosion. A field of winter rye stands out sharply amidst plowed areas of typical chernozems; in the zone 590 nm these differences are con- siderably weaker, but sectors of freshly plowed chernozems stand out better as a result of an increase in surface moisture content. In the field of winter rye it is easy to see a banding wliich is associated with the dif- ferent nature of working of the soil, which is completely absent on photo- _ graphs of the red spectral zone. Thus, a comparison of the photographs taken in different parts of the spectrum makes it possible to increase the interpretability of soils and agricultural fields. ~ In this connection, in our country and abroad great interest is being shown in study of the spectral characteristics of soils and agricultural crops surveyed in different zones of the electromagnetic spectrum. Inves- _ tigations indicated differences in the srectral reflectivity of soils in dependence on their comnosition and state. It was established that there _ 3s an influence of the humus content, light-colored compounds (silicon and aluminum), carbonates, easily soluble salts, different iron compounds, and also moisture content and mechanical composition of the soils on the characteristics of spectral distribution of reflected radiations of soils. The curves of relative spectral reflectivity of soils (sands, clayey loams), determined under field conditions (Holmes, 1970), indicated that the maxi- mum of the differences falls in the zone 0.6-0.711- m. This is one of the 43 _ FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007102/08: CIA-RDP82-00850R000300050024-7 surve,y zones adopted in working with the ERTS satellite. An increase in soil moisture content to complete capillary moisLure cap- acity reduces their reflectivity by a factor of 2-3 (Obukhov, Orlov, 1964). Yu. S. Tolchel'nikov (1959, 1974) notes that during summer under field conditions the soils dry out from the surface to an air-dry atate. Accordingly, with a uniform mechanical composition thc brightness of the soils has a direct relationship to its humus contento N. P. Sorokina (1967) for typical chernozems studied the correlations b =Lween the coefficient of reflection for soils and their humus and car- bonates content. It is shown that with a humus content of less than 5% there is a direct relationship between the quantity of humus and ths log- arithm of integral soil reflection. The coefficient of spectral reflection of soils has been proposed; RC is determined using the formula - RC = 440 + 490 + 540 + 590 + 640 + 690/6 where 440, 490 and the others are the reflection values for wavelengths - 4402 490 nm, etc. In this section we will examine the spectral reflectivity of soils and its influence on their brightness in different spectral'zones. The coefficient of spectral reflection of soils is the ratio of the reflec- tion value of the soil sample to the value for an ideal surface reflecting 100% of the light for all wavelengths. The term "reflection coefficient for soils" coincides with the term "brightness coefficient" (Krinov, 1947). For a definite wavelength X it can be determined using the formula , r;k = B a /Bp where B;, is the brightness of the soil surface and Bp is the brightness - of the standard (byrate plate) for identical illumination conditions. Whereas in an analysis of the photoimage of soils on integral panchromatic photographs it is more important to take into account the reflection coef- ficient in the visible part of the spectrum, in a multizonal survey it is necessary to take into account the reflection (brightness) of soils at a def inite caavelength. The reflection coefficient for soils (with an accuracy to 0.1%) for a def- inite wavelength was determined directly from the spectral reflection curve, registered with a spectrophotometer. The SF-10 recording spectropho- tometer makes it possible to obtain the absolute reflection value in the visible zone of the spectrum 400-750 nm. In the analysis use was made of ai;�-dried samples passed through a 0.25-mm sieve.

It can be seen that the total integral reflection coefficient for typical chernozems in the entire visible zone of the spectrum on the average is 10.7%. Some very ' insignificant increase in brightness was observed for typical chernozems - with an increase (up to 11.8%) of effervescence. Meadow-chernozem soils are close in reflectivity to chernozems (Fig. 2). _ In a dry state they cannot be distinguished in plowed land. The differ- ences in meadow-chernozem soils against the background of chernozems are attributable to their different moisture content. They are reliably interpreted due to the nonidentical deve].opment of vegetation in these soils. r, % SO - 40 30 3 2U - - _ _ _ 2 f0 0 400 500 600 700 NM nm Fig. 3.

On photographs they are reliably interpreted - from the light gray image tone. In a multizonal aurvey of an experimental sector of the steppe zone use was made of photographs in the visible zone of the spectrum sensitive to the green (520 and 540 nm) and red (610-690 nm) zones. In the green and red spectral zones the reflection of typical chernozems and meadow- chernozem soils is almost i.dentical. In the green zone these soils are more readily cliscriminated from calcareous excavated chernozems (the difference in the reflectivity of these soils in the green zone is 1.1- 1.2%, in the red zone 0.6-0.7Y). The differences in reflection be- tween chernozems and their eroded varieties are sharply expressed in hoth the green and red spectrai zones. the spectral reflectivity of soils in the experimental sector in the dry steppe zone was analyzed for the three principal regiona of this zone. Dark chestnut sandy loam, meadow-chestnut soils and aolonchaks were stud- ied in the territory of an undulat�ing sandy plain. All these soils, espec- ially solonchaks, are readily distinguished from one another on the basis of the mean reflection coefficient in the visible zarne (Table 11). The spectral reflection Curves for these soils are given in Fig. 3. In an experimental sector of the dry steppe zone multizonal surveys were made at 520 and 540 nm, 610 and 690 nm. A comparative analysis of the re- - flectivity of soils in the green and red zones indicated the following. The greatest difference in the reflection values for dark chestnut and meadow-chestnut solonetz-like soils is observed in the red (610-690 nm) zone 5.4 and 6.1% respectively; in the green zone (520 and 540 nm) zone it is 2.7 and 3.1% respectively with a 4% difterettce in reflectivity of these soils in the entire visible spectral zone. Salina and meadow solonchaks, having a salt crust on the surface, can be represented by an identical tone because the reflectivity of the salt - crust (except for the blue-green zone) is close for them. However, solon- chak vegetation is usually present at the surface of ineadow solonchaks. J Accordingly, on the photographs they differ reliably from salina solon- - chaks. The difference betwsen dark-chestnut and meadow-cheatnut soils can be seen shArply, since for these RC = 12.5-14.9%; for meadow-steppe and steppe solone*_z soils, however, RC = 23.3-24.3�6 (Table 12). The differences in the reflectivity of dark chestnut solonetz-like and meadow-chestnut soils are seen better in the red (610 and 720 nm) apectral zone 3.4 and - 4% respectively, with a general average of 2.4�6. In the blue-green zone the corresponding figure is 1.4-2.29;. . 46 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY _ E r, % 40 _ ~.,..,4 30 . ~ 3 2U /0 - Oti00 50b G00 700 Hff nm _ Fig. 4.

These differences were also especially clearly established from space photographs of this territory during the spring survey period when a high soil field moisture content was expressed in a decrease in reflection of ineadow steppe solonetz soils. _ The reflectivity of soils was also studied in the territory of plateaus. _ with dark chestnut calcareous, meadow-chestnut calcareous and dark chest- nut calcareous excavated soils ofsmall hillocks. The_ref].ectivity of these soils is shown in Fig. 5. The dark chestnut calcareous and meadow chestnut calcareous soils have a close general reflection coefficient 20.0 and 19.1% respectively (Table 13) ; it wae svmewhat higher in the red - spectral Lone - 24.4-27.6 and 22.8-26Z; in the blue-green zone the dif- ferences in the reflection of these soils are equal to 0 or not more than 1%. In.the dry steppe zone dark chestnut and meadow chestnut soils were most ef�ectiveZy interpreted from photographs taken in the red spectral zon2. Dark chestnut calcareous excavate3 soils @mall hillocks [at the mouth of marmot burrows] --,as a result of the considerable content of - carbonates and the lesser humus content in the upper tilled horizon have a high reflectivity. On the photographs, in the green and especially in the red spectral zone, they were represented by a light gray, almost white tone. As a result of study of the spectral reflectivity of soils in the steppe zone it became clear that the lesser the humus content in the soil, the greater is the reflectivity and the lighter is the soil image on the pho- tographs. These indices are especially important in the interpretation of plowed sectors of the soil cover in the steppe zone. :teflectivity measurements quite clearly indicated that the calcareousness or rock material is manifested sharply in the blue-green spectral aone, close to the ultraviolet, where very low reflection coefficients are noted - for the soils. At the same time, study of the spectral reflectivity of soils revealed the necesaity for taking into account not only the general reflection coef- ffcient, but also the peculiarities of refleetion in a specific spectral zone. Their investigation make4 possible a still greater increase in the effectiveness of sail cover interpretation. The spectral peculiarities of the soi7.a and agr3.cultural crops, manifested in different tonality on multizonal photographs, constitute an important interpretation criterion. Spectrometric survey of soil cover. Work is successfully developing on study of the spectral brightness of the earth's surface synchronously un( - ground conditions, from aircra.ft and from space. 48 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007102/08: CIA-RDP82-00850R000300050024-7 - FOR OFFICIAL USE ONLY As a result of investigation of spectral reflectivity of soils and vege- tation (Kondrat'yev, et al., 1972) in the territory of a sandy desert and from space from the "Soyuz-9" from an altitude o� 250 km (synchron- ously) it was possible to define two fundamental prineiples: 1) during a survey from space there is an increase in the total brightness of Ci:e ~ soil-vegetation associations in comparison with surface measurementa; 2) perticularly sha.rp differences in their reflectivtty are observed in = the blue-green region of the electromagnetic spectrum (Fig. 5). A spectrometric survey o� the earth's surface does not give images in the - form of photographs. It serves for obtaining the apeetral characteris- ~ tics of sofls and areas of agricultural crops and the choice of the op- timum survey zones in a multizonal survey (Raehkul3k, Sitnikova, 1976; Tolchel'nikov, Chukov, 1977). For exampZe, ground investigations carried out for study of the aurface moiature content of typical chernozems in an experimental sector of the steppe-zone using a spectrometer operating in the spectral range 0.4-0.5� m indicated that the soil dries out rapid- ly from the surface and moi.sture content exerts little influence on the - spectral brightness coeff3cients of the soil (Bulatov, et al., 1976). In comparison with a photographic survey,* a spectrometric aurvey for each - _ soil or agricultural crop, in dependence on the seleeted spectral range - and epectral resoluti.on of the apparatus, can give a large number of char- _ acteristics. According to data published by Vinogradov and Kondrat�yev - (1971), it appears that in the range AA0.4-0.7t1m with a spectfal resolu- tion L1,'A0.5 �m in one spectrum it is possible to obtain up to 60 charac- teristics of one so31. An important index is the ratio of the spectral brightness coel"ficients (K for definite spectrai intervals. It is as- - sumed that K a= r'` red 0.64 - 0, 66/r aIR 0. 81-0. 85 fd m is of interest fox evaluating moisture content and ttte humus content in the soil (Vinogradov, 1976). _ A spectrometric survey is of great imgortance for the sensing of agricu].- tural crops. A study made by foreign specialists in one such experiment _ using about 40,000 spectra of these cropa indicated that for the recog- nition of plan.eings of soq beans, corn, oats, wheat and red clover it is most effective to study their spectral brightneesea in three ranges: 0.40- 0.44, 0.66-0.72, 0.72-0.80 � m. The percentage of eorrect identification of these crops is 85-92%. . We note in conc?i-isjon that spectrometric sensing of soils and sown crops, based on reg-stry of the refl.ection spectra of suna.ight and the charac- teristic emission of the earth's surface, with reapect to the peculiarit- - iea of the measurement method, ean be subdivided into: 1) visible and near-IR 0.3-1.10m; IR, or thezmal 3.0--300 �m; 3) microwave (milli- meter, centimetex and decimetex radiations). 49 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02108: CIA-RDP82-00850R000300050024-7 At the preseut time thesa methods for studying soils and agricultural crops are in the stage of experimental development in our country. ' Interpretation of Soil Criteria _ The specific nature of tnterpretation of the soil cover relates, in par- ticular, to the principal criteri.a (direct and indirect) used in the in- terpretation of aerial and space photographs. The direct interpretation criteria for the soil cover are tone, color, pattern (texture of the photoimage), size and shape of th,e soil units; the indirect criteria are nature of relief and hydrography, vegetation, man's agricultural activity. In soil interpretati.on it is infeasible to be guided by any one interpret- ation criterion, such as phofiotone. The most correct analysis of the pho- toimage of the soil cover can be made only when all the interpretation criteria are taken into account. Tone of Photoimage; its Visual and Quantitative Evaluation - The tone of a photoimage of soil and agrieultural features on aerial and space photographs is one af the important, but rather variable criteria. Visually in soil interpreCation it is possible to make successful use of _ ' a gray scale of tones having the .following seven stages (Mikhaylov, 1959). Tone Density 1. Wfiite 0.1 or less _ 2. Almost white 0.2-0.3 3. Light gray 0.4-0.6 - 4. Gray 0.7-1.1 - 5. Dark gray 1.2-1.6 6. Almost black 1�7-'2�1 - 7. Black 2.2 or more Visually i*_ is possible to discriminate nine tones: 1) white; 2) almost - white; 3) light; 4) light gray; 5) gray; 6) dark gray; 7) dark; 8) Rlmost black; 9) black In soil interpretation the presence of a tonal difference between adjacent soil units ia exceptionally important. The interpretation of the soil cover will be difficult or impossible if its image tone merges with the general hackground of the terrain and therefore the transmission of the boundary optical image contrast (difference in image tone) is the pri- mary criterion of interpretability of soil formations. In actuality, if the surf.ace brigfitness of one soil,unit does not differ from the surface b.r3ghtness of another, the boundary between them will not be visible on - ar aerial or space photograph. . 50 _ FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02108: CIA-RDP82-00850R000300050024-7 , j ' FOR OFFICIAL USE ONLY The brightness contrast is characterized by the cmntrast value: Kbr a B1 - B/B, where'B1 is the brightness of the objeet= B is the brightneae of the back- ground surrounding tTie object. Tbe minimum brightness difference which is die criminated by the eye and which is detec*_ed bv the photoemulsion is the contraet threshold and this is denoted !lB/B (d B is the minimum brightness difference between the oliject and the background perceived by the eye). The brightness contrast threshald fvr the human eye is N2Xo If the contrast be- tween a soil unit and the surrounding background is above the threshold of contrast sensitivity, it is reflected by the photographic emulsion. _ In addition to a visual evaluation of the tonality of different soils and , sowm cropa, it is possible to carry out quantitative measuxements. Micro- - pho tometers of the MF-4, IFO-451 and other types are used in measuring the different density of aerial pTiotographs. - Using a new electronic instrument, the "Kvantimet-720" image analyzer, it is possible to discriminate 64 levels of gray tone from photographs and f rom films. On the basis of numerous visual-instrumental determinations these 64 detection levels, in dependence on the determination of the gray tone on aeroapace photographs, were classifiQd into 11 steps in the fol- lowing way: 1. Black 0-10 7. Gray 35-40 2. Atmost blaek 10-15 8. Light gray 40-45 3. Gray-black 15-20 9. L3.ght 45-50 4. Dark 20-25 10. Almost white 50-55 _ 5. Dark gray 25-30 11. White 55-64 6.

The maximum dissection of the lands with a con- siderable participation of moderately and strongly eroded soj.ls is inter- preted from a photograph in the region of tfie upper course of the Oskol River (40-50%). A minimum dissection of lands of the gully-ravine network is a characteris- tic of watersheds in the neightiorhood of the town of Livny (10-20%). Alluvial-meadow soils of river floodplains show up on the phatogLaph in an almost white tone. Among the agricultural crops a light gray tone is char- acteristic of fields with winter whea.t. An almost white tone is character- istic of fields with winter wfieat. An almost wfiite tone is characteristic for plantings of perennial grasses (sweet clover, clover, timothy, alfalfa). A gray tone corresponds- to fields of spring wheat, barley snd a vetch-oat mixture. Forests and virginland vegetation of the meadow steppe do not dif- fer and show up in a light gray tone.

A microphotometric profile which we ohtained from this space photograph of an experimental sector of the steppe zone and the territories adjacent to it makes it possible to distinguish the following.

It was demonstrated that in the zone 115 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 10 50 90 L,KM APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY 0.7-0.8 w m these crops during the spring period show up in a light, almost white tone. The middle segments of tfie curve with poorly expressed peaks correspond to the image of plantings of spring crops. An analysis of the phDtoimage of the sgace photograph taken in the IR spec- tral zone (0.8-1.1 fXm), in comparison with tlie 3ust examined photograph, - did not rp-veal special fundamental differences with respect to the inter- pretation of soils and plantings of agricultural crops. On a late summer space photograph, taken in the zone 0.7-0.8f.tm, as indi- _ cated hy our investigations, an almost black tone corresponds to the plow- ed surface of typical chernozems and meadow-chernozem soils (Table 21). Considerable spaces on the photograph have a light gray photoimage tone which corresponds to fields covered witli the stubble of grain crops. Against a light gray background through.virginland vegetation it is vir- tually impossifile to interpret meadow-chernozem soils associated with longitudinal trougfis and ravines, as was demonstrated for the spring per- iod. On the basis of a light gray tone it is possible to discriminate areas of gray and dark gray forest soils. On the basis of an almost white tone there is reliable interpretation only of alluvial-meadow soils of - such large steppP rivers as the Seym. Small steppe rivers, as well as the nature of the erosional dissection of the territory, are not determined from the summer photograph or are interpreted unreliably. Among the dgricultural crops fields of corn, sugarbeets and alfalfa have an almost white tone. Fields of harvested corn have a gray tone. Forests - and virginland steppe show up in a light gray, almost white tone. Clouds are a considerable obstacle to the successful interpretation of the soil cover and agricultural crops; these show up on the photographs in a gray tone, whereas the shadows cast from clouds onto the earth's surface � have an almost black tone. It is very difficult and sometimes almost im- possible to use a suunner photograph in the zone 0.7-0.8 � m to interpret the presence of small cumulus clouds. On the ground the shadows from it show up as small spots of an almost black tone which with respect to image tone merge with plowed fields with chernozems and meadow-chernozem sotls. The photoimage of the soil-vegetation cover on a space photograph taken in the red zone of the electromagnetic spectrum (0.6-0.7 �.m) has a fundamen- tally different character in comparison with the photograph just consider- ed. On this photograph a gray tone shows sectors of bare fallow and plowed fields with a direct image of the soil surface. Against a general gray and light gray background of the photograph, against an almost white or light gray tone along the right bank of the Oskol, Rat' and Tuskar' Rivers, it is easy to interpret gray and light gray forest soils with the participation of eroded soils and semiconsolidated sands. In the IR zone fields with corn, sugarbeets and alfalfa have an almost _ white tone; in tfie red zone they appear in a dark gray or almost black tone. 116 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-00850R000300054424-7 The stubble of grain crops and corn, due to the high reflectivity of 3traw and afterharvest remnants, is interpreted from a light-gray or al- most white image tone. The forests have an almost b lack tone, whereas the - virgin land of mixed grass vegetati.on has a gray tone. Accordingly, on this photograph they are easily discriminated from one another. The images of alluvia]-meadow soils of tFie floodplains of such steppe rivers as the Seym are characterized by gray and dark gray tones with a poorly discrim- inated internal differentiation of the soil-veget,ation cover on the flood- _ plain. The clouds on this photograph show up in a white toiie but their shadows are almost black, wliich makes it difficult to discriminate them from forest areas. A comparative analysis of the space photographs taken at different survey times indicated that they mutually supplement and enrich one another with respect to a more complete transmission of in.formation on the soil and ag- ricultural resaurces of the investigated natural regions. It was estab- - lished that the surface of typical cherno2ems and meadow-chernozem soils - on both spring and on summer photographs shows up in a dark gray tone in the range 25-39 units of the gray tone level, wherea.s fields of alfalfa and perennial krasses have'an almost white tone, equal to 50-60 units. Ad- ditional significant data on the soil-vegetation cover can be obtained when using space photagraphs of different spectral s urvey zones. 117 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 FOR OFFICTAL USE Oh'LY Chapter 5 INVESTIGATIONS OF SOILS FROM SPACE PHOTOGRAPHS - During recent years there has been ever-increasing use of space photo- graphs and methods for remote observations in agriculture boCh in our country and abroad. Fundament;=1 Russian publications (Beregovoy, et alo, 1972; Vinogradov, Kon- drat'yev, 1971; Gonin, Strel'nikov (editors), 1975; Grigor'yev, 1975; Vino- gradov, 1976; ISSLEDOVANIYE PRIRODNOY SREAY KOSMICHESKIMI SREDSTVAMI, 1973, 1974, 1975, 1976; Rodionov (editor), 1973; METODY DESHIFRIROVANIYA, 1976; ISPOL'ZOVANIYE KOSMICHESKIKH..., 1977; Kravtsova, 1977; KOSMICHESKAYA S"YERCA..., 1979; AEROKOSMICHESKIYE..., 1979) examined the general prob- lems involved in the interpretation of space surveys, including their use in the study of the soil and vegetation cover. Abroad these matters have been dealt with in systematic aids (MANUAL OF REMOTE SENSING, 1975; Bar- rett, Curtis, 1976). - Space methods ensure broad possibilities for obtaining information on the use of terrestrial resources in agriculture (Table 22). Soviet and American specialists in the field of use of space photographs for agricultural purposes assume that about 90% of the data necessary for rational land use can be obtained using aerospace methods. The latter -make it possible to identify the principal categories of use of agricul- tural lands: cultivated lands with different types of agricultural crops, meadows, pastures, fallow lands, etc. Remote methods constitute an impor- tant tool for the successful solution of agricultural problems. In 1968 the US Department of Interior outlined a program for investigating natural resources using artificial earth satellites of the EROS type (Earth Resources Observation Satellite), a satellite for observing the - earth's resources. In addition to NASA, the US Department of Agriculture and other departments are taking an active gart in this program. One of the principal aspects of this program is obtaining,the space photo- graphs necessary for compiling and revising different types of special maps (Cfllvocoresses, 1975). This objective is one of the most important as well in the Soviet program for the use of space materials (Bryukhanov, Makhin, 1973; Salishchev, et al., 1975; Kiyenko, Kel'ner, 1976; Zonn, 1977; Knizh- - nikov, Kravtsova, Fivenskiy, 1975; PRIMENENIYE..., 1978). 118 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-00850R000300054424-7 - In the US and USSR space programs for the study of natural resources great attention is being devoted to solution of practical problems. Below we will describe a number of matters which are being dealt with in this pro- gram for the use of space materials in the field of agriculture. The inventorying of agricultural fields provides for investigations for measuring the areas of agricultural fields, establishing the boundaries between fields and wooded areas, preparation of maps showing agricultural _ crops, and also compilation of special speedily prepared maps of agricul- - tural fields based on satellite data. The estimating of the yield of agricultural crops provides for investiga- tions of the use of space data for determining the state of virginland vegetation and agricultural fields, the degree and area of weediness and diseases of agricultural crops, shortages of moisture for growing vegeta- tion, and also for routine monitoring of the state of wintering of winter crops, estimation of the productivity of hay fields and pastures. Improvement in use of arable land. In solving this problem plans call for investigations for studying the structure of the tilled soil layer, for determining soil moisture content and temperature, the needs of soils for drainage and irrigation, degree of erosion and salinization of soils, for evaluating the results of recultivation of soils, for deterniining the re- gions subjected to frosts and the falling af precipitation, for detecting the shortage of nutrients in the soil, for the mapping of different types of soils wieh clarification of structure of the soil cover, for regional- ization of soil resources. The soil-agricultural interpretation of photographs taken from space makes it poss.ible to have data on a global and regional scale on the soil cover and on plantings of agricultural crops. Among the specific properties of soil-agricultural intermination are extensive caverage, sma.ll scale and - generalization of the photoimages of features. i Coverage of Space Photographs and Study of Soils In comparison with materials from an aerial survey, space photographs cover enormous areas oi the earth's surface. Depending on the frame format, - - fo cal length.of the objective and survey altitude the area covered by one _ photograph will be different. Space photographs of extensive territories of the earth for the first time are making it possible to see objectively - - the nature of the soil cover of individual regions and provinces, indi- vidual m:)untain systems and the vertical zonality associated with them. On a space photograph of the territory of the southwestern part of Morocco, - obtained as a result of flight of the "Gemini-5" spaceship from an alti- tude of about 280 km at a scale of r'1:900,000,it is easy to see the coast- al rt:gion near Sidi Ifni and the marginal part of the Atlas and Antiatlas _ mountain system (Fig. 19, 19a).

Mountain cinnamon soils and mountain cinnamon soils eroded to different degrees are formed here under sub tropical for- est or scrub. Beneath forests these soils appear on the piiotograph as dark _ gray and under thin forest in a gray tone with a folded-corroded structure of the photoimage characteristic for mountainous areas. In the northwest, in the coastal sector, the Antiatlas I4ountains border an extensive lowland with elevations less than 200 m. The vegetation is rep- resented by thin forest with the argan tree, thorny scrub with a predom- inance of acacia and jujuba, as well as desert-adapted grass associations. Cinnamon soils, gray soils of subtropical semideserts, irrigated gray soils o.f oases and black subtropical soils are developed here. On a space ph.oto- graph, against the uniform gray background of the image of the desert land- s.cape of the coastal lowland with its cinnamon soils, it is easy to see dark spots sectors occupied tiy oases. The gray soils of the subtroplcal - semideserts have a light gray tone of the photoimage. A dark gray tone clearly reveals the moister sectors of irrigated gray soils and black sub- ' tropical soils. A lowland with sandy soils extends in a narrow band along the Atlantic coast in the lower part of the photograph. Another space photograph, taken during the flight of the "Gemini-4" space- ship over the territory of Oman, in great detail (at a scale 1:750,000) reveals the nature of the earth's surface in the eastern part of tre Arab- ian Peninsula (Figures 20, 20a). We carried out soil interpretation using a soil map of Asia based on black-and-white and color photographs. The al- titude of rhe survey was 180 km; the area of the survey was 22,500 km2. The color photograph clearly shows sand dunes in a reddish-yellow color with the crests extending from north to south for tens and hundreds of kilo- meters parallel to the prevailing wind direction. Chains of mounfiains rise aharply from them to t}ie northeast; these mountaine of Oman rise up to 3,000 m.

The soil cover l.y repre:ieited by reddisti-hrowri mauntain soils of the savanna nnd is char- acterized by extensive occurrence of rock debris. _ Tlie pllotograph clearly shows a finely corroded folded dendritic pattern of - a gray tone associated with erosional dissection of the surface, the di- rection of the mountain folds and dry valleys. A very rocky foothill zone around the mountains with a width of about 20 km is clearly interpreted from the more uniform-homogeneous pattern. Dry rocky wadis are represented ' on the photograph by the light-colored veins of the dendritic pattern. Reddish-brown desert-adapted savanna soils are formed in the foothill szc- tor. Along the southeastern part of the peninsular coast the light gray tone on the photograph represents a zone with coastal off-shore bars and gentler relief forms than in the foothill and especially in the mountainous _ part of the territory. This zone consists of soils of the tropical deserts, 120 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 - and in the sector transitional to the mounta~ris there are reddish-brown desert-adapted savanna soils. Individual snall spots and dark points along the boundary of dunes and along the coast correspond to cultivated oases. - Swamps, lagoons and residual lakes have the darkest tone on the photograph.

The survey was made from the "Gemini-4" spaceship. a Small Scale Properties and Generalization-of Soil Photoimage An i.mportant characteristic of a space survey is that the photographs are small scale. The photographs may be of a very small scale, about 1:10,000,000 - 1:100,000,000 and smaller, with great generalization not only of the soil-vegetation cover, but also relief forms on the earth�s surface. Such photographs are used for scanning purposes. Both in our country and abroad rather extensive use is made of small-scale photo- graphs at a scale of 1:1,000,000 - 1:2,500,000. These space photographs can be used in small-scale soil mapping. The optical generalization of the soil cover, which is reflected in the nature of the photoimage of these photographs, makes possible successful interpretation and ma.pping of zon- � al and especially intrazonal soils and dettction of"erod"ed-. and'salinized sectors revealing a different character of agriculturajoIand use. 123 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 I FOR OFFICIAL USE ONLY Table 22 Possibilities of Use of Space Research Methods in Agriculture (AGRICULTURAL APPLICATIONS..., 1967) Field of application Necessary resolution rela- Interpretation methads tive to maximum possible theoretical resolution in: photographic IR and photographic IR and infra- infrather- methods thermal methods mal - Determination of Minimum Developed Not developed, principal types of - land use Observation of " Same Same soil cover Observation of - water resources Mapping Minimum Unsuitable " Ohservation of MinimiTm Partially state of pastures developed Observation of ag- ronomic conditions Same Determination of Average Mj.nimum " types of agricul- tural crops Observation of in- Maximum tensity of develop- ment of agricultural crops u n Determination of yield of agricul- tural crops Observation of " Piot developed - farm animals 124 _ FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY Table 23.

Soils: 1) mountain reddish-brown savanna soils; 2) mountain reddish-brown soils of dry savannas; 3) reddish-brown highly rocky desert- adapted savannas; 4) reddish-brown desert-adapted savannas of intermont - basins; S) soils of tropical deserts; 6) soils of tropical deserta with sandy off-shore bars; 7) ridged deflatable and semiconsolidated sands; 8) irrigated soils of oases; 9) coastal lagoons and swamps. _ Applying specialized photographic systems and artificial earth satellites it is possible to obtain space photographs at the inrermediate scale of _ 1:100,000-1:200,000 which with a high detail impart the image of the soil cover, the nature of the mechanical composition, different humus content, moisture content, erosion and salinization of soils. At thp present time the most widely used scales of space surveys are � 1:10,000,000 - 1:1,000,000 or larger. A survey at scales 1:100,000 - 1:1,000,000 is promising for study of the soil cover on a regional basis. _ The choice of scales of these photographs is determined by the necessary accuracy in soil mappinb. An an3lysis of space photograpYls taken from the "Soyuz-9," "Soyuz-12" and "Soyuz-22" spaceships and the "SaTyut" orbital station indicated that these photographs can be used in compiling and correctfng a soil map at a scale of 1:1,000,000. Data from foreign authors show that materials from the "Apollo-9" space- ship at a scale of 1:3,000,000 were used in compiling a phn tomap at 1:250,000, whereas the photographic systems of the "Skylab" orbital station _ ensured the preparation of maps at a scale of 1:118;000 with an initial survey scale of 1:2,500,000. - The p,roblems involved in the generalization Qf space photographs are insep- arable from complex special mapping. In order to compile internediate- and small-scale soil maps it is desirable to have a sc:ale of space photographs _ (enlarged from the original by 2X-4x or 3x-5X) identical wi:th :.he mapping 135 ' FOR OFFICIAL USE ONLY ! s- Li APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 scale (Kravtsova, 1974, 1977). This is associated not only with the tech- nical conveniences for work with space photographs, but also with the sim- ilar generalization level. - An important characteristic of a space surve:y is that on space photographs there is an objective optical generalization of the earth's surface and soil cover. In order to analyze this problem we studied the possibilities of interpretation of the soil cover of the dry steppe zone in the region of the "Tsimlyanskiy" sector on the basis of a space photograph and mat- erials from an aerial survey. The scale of the sp3ce photograph taken from the "Soyuz-9" ship in June 1970 was 1:2,500,000. The sca.le of the aerial photographs is different. The photographs were black-and-white. In carrying out the work we compared ancl analyzed the,photographic images of different soils on the aerial photo- graphs and on the spac.e photograph for the territory of different natural regions. We analyzed sectors of different water�divides, terraces and flood - plains of a steppe river. The materials of field checking are given wi*h an indication of the morphological and physicechemical data for the investigat- ed soils (Table 23). _ The s.pace photograph and small-scale maps were used in identification and geographical tie-in to the terrain. This was done most easily using a , photoimage of the shores of the Gulf of Taganrog, Tsiml.yanskoye Reservoir and Lake Manych-Gudilo. The meanders of the lower course of the Don and . Manych Rivers show up clearly. Due to cloud cover the Sa1 River could be traced reliabiy only in the lower mouth reach; the remainder of the course had to be plotted approximately. The second plement afcer the.hydrographic pattern which could be determin- _ ed from the space photograph is the character of agricultural use of the - ter.ritory. On the basis of the c3egree of Iand use exploitation it is easy to distinguish three soil-geographic regions: light chestnut soils with a minimum percentage of tilled land, chestnut soils, where exploitation in- creases sharply to 30-40%, and southern chernozems which are 50-60% tilled.. However, against the image background of chernazems it was impossible to see micellar-calcareous thick and very thick soils with plantings of ag- ricultural crops. This is evidently associated with the time of the survey _ (mid-June). During this period fields with plantings of winter wheat, which predominate in this region, merge on the photoimage with the soil surface. All three principal components of the soil cover - micellar-calcareous chernozems. meadow-chernozem, meadow-chernozem solothized in the ter- ritory of the Azov-Kuban plain were clearly traced on large-scale aerial photog�raphs. Using medium-scale aerial-photographs meadow-clzernozem soloth- ized soils, due to the sma.ll size of the depressions, were interpreted with difficulty. An analysis af similar soi.ls on a space photograph indicated _ that in the process of optical generalization the meadow-chernozem soils _ of 1ic11oGZS and depressions merge into a single contour of a dark gray tone characteristic for the photoimage of micellar-calcareous chernozems. 136 = FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY - Another experimental sector took in the marginal watershed eroded part of Sal'sko-Manychskoye interfluve and the terrace of the Manych River. On the aerial photograph the eroded chernozems with a Iuumus content of ahout - 4% show up in a light tone. The soil cover of the terrace is complex. Here there is representation of cfiernozem-�meadow solonetz-like soils with soil- ground water at a depth of 2 m. On the aerial photographs these soils ap- pear in a dark gray tone due to increased moisture content and a quite good supply of humus. Meadow solonchak-like solonetz soils are another component of the soil cover on the terrace. On aerial photographs they show up in a light gray tone of an intricate pattern. A still brighter light tone is characteristic of the image of ineadow solonchaks, which at the surface have a salt crust. In general, the terrace photograph has a clearly expressed fine-riFabed intricate pattern characteristic for a com- plex soil cover with solonetz soils. - An analysis of a similar territory on a space photograph indicated that this complexity of the soil cover and the high percentage of participatiQn of ineadow soils, solonetz soils and solonchaks is reflected in a nonuni- - form pattern of a gray and dark gray tone on the photoimage of the space photograph. Tne third experimental sector is the floodplain of the steppe Don River. The floodplain surface has a complex relief consisting of sandy crests, clayey loam depressions between the crests, distributaries, present-day and ancient ox-bow lakes and flat leveled sectors. Alluvial meadow sandy and sandy loam soils are formed on the sandy crests. On aerial photographs these soils are easily interpreted from the curved form of crests with a bright-light tone. In the more moistened depressions - between the crests there is development of alluvial meadow qlayey loam sand-permeated soils. On aerial photographs they have a gray or dark gray tone, depending on the degree of moistening and the huffius content. On a relatively flat sector of the floodplain, made up of clayey loam and heavy clayey loam saline deposits,there are alluvial meadow solonetz-like and solonetz-solonchak-like soils. On the aerial photographs these soils show up in a gray tone. Agaiiist the background of these soils, due to a dark gray tone and a curved crescent shape, it is easy to interpret long, narrow " troughs, poorly expressed in the relief, greatly leveled depressions be- tween the crests and silt-filled ox-bow lakes. Alluvial moist-meadow sol- onetz-like heavy clayep loam soils have developed here. In former ox-bow lakes, well expressed in the relief, there are alluvial meadow-swampy and - swampy soils which on an aerial photograph are clearly interpreted due to _ their affinity to ox-bow lakes and the dark image tone. The photograph = showed the first terrace above the floodplain with highly solonetzic = combined soils and solonetz soils. The solonetz compZex shows up in a nottled pattern with a light gray tone. A study of the photoimage of this sector from a space photograph indicated that the soil cover of the floodplain and the territory of the first ter- race above the floodplain do not differ from one another and show up in a complex pattern of a gray and dark gray tone. 137 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 . _ The results of a comparative analysis of small-scale soil maps and the space photograph indicated the following. On the space photograph the - area of micellar-calcaieous chernozems adjacent to the Gulf of Taganrog shows up in a dark gray tone of a uniform pattern. Southern chernozems have a similar image tone. However, in the areas of southern chernozems _ it is easy to see rectangles of fields with plantiags of agricultural crops. They are particularly clearly visible in the southeastern part of the Sal'- - sko-Manychskaya Ridge on the bouadary with chestnut soils. SoutfieYn chernozems in combination with meadow-chernozem soils, situated on the high terrace of the Don between its valley and the Lower Don Caaial, - were reliably interpreted from the darkest photoimage tone. This tone, on _ the one hand, is associated with a considerable humus content (about 4%),. and on the other hand, with a high soil moistjxre content, since a consider- able area between the Lower pon Canal and the Lon val3.ey is a zone of inten- - sive irrigation. A considerable area to the south of the Tsimlyanskoye Yeservoir, where southern chernozems and especially chestnut soils are encountered, is ' covered by noncontinuous cloud cover, but it masks the surface image. Only in the region of tfie southeastern tip of the Sal'sko-Manychskaya Ridge does the cloud cover disappear, and from the photoimage oti the space photograph it is possible to determine clearly and map areas of chernozems, chestnut and light chestnut soils. With respect to the image tone the _ chestnut and light chestnut soils with a high participation of solonetz soils are similar. They show up in a light gray tone, but chestnut soils have a considerably higher percentage of cultivation in the territory. There is very reliable interpretation of the boundary in the neighbor- hood of Lake Manych-Gudilo between light chestnut soils with a high par- ticipation of solonetz soils and southern chernozems. On a space photo- graph at the western tip of Lake Manych-Gudilo an area of ineadow-chestnut soils also stands out sharply against a light gray background of light cnestnut soils. It shows up in a mottled pattern of a dark tone with light gray spots. On space materials a study was also made of the degree of gendralization - of the soil cover of the dry steppe Zavolzh'ye region. For these; purposes use was made of a space photograph at a scale of 1:2,500,000 for the ter- ritory of the Syrtovoye Zavolzh'ye steppe zone, taken from the "Salyut-4" orbital station, whereas as a"key" use was made of a soil map of one of the farms of this territory at a scale of 1:25,000 which we compiled earlie'r (under the editorship of Doctor of Agricultural Scien ces V. A. Nosina) using aerial photograghs at a scale of 1:17,000. The investiga- tions indicated that on a space photograph on the basis of the different tiexture of the photoimage there is reliable discrimination of southern chernozems developed on watersheds with areas of eroded soils (complex dendritic texture) and southern chernozems formed on terraces (uniforai or wideiy spaced dendritic texture). The complex pattern of the photoimage of the soil cover of terraces, discriminated from aerial photographs 138 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE OI3LY - (sauthern chernozems of different thiclrness, excavated chernozems, meadow- chernozem soils), on a space photograph had a uniform image of a dark gray tone. On watersheds and terraces on the basis of a dendritic pattem of a light gray tone there is reliable interpretaCion of eroded and "washed" soils of gullies and ravines and meadow-chernozem soils developed on their bottoms. As a result of a comparative analysis of the optical generalization pro- cess it was established that on space photographs at a scale of 1:2,500,000 for the territory of the Syrtovoye Zavolzh'ye it was possible to deter- mine 5-6 of the soils of the 20 reliably interpreted from large-scale - aerial photographs. In the course of generalization there is a quantita- tive and qualitative selection of soil areas and generalization of their configuration. In the theory of space interpretation of the soil cover, due to its gener- = alization, it is possible to introduce the concepts of simple and complex integration. The first is characteristic for the representation of soil combinations on a photograph, whereas the second is characteristic of rep- _ resentation of soil combinations and soil complexes on a space photograph. The joint use of aerial photographs and space photographs of different scales indicates that as a result of optical generalization there is rep- resentation of a different structure of organization of the soil cover. At - present a study of different types of structures is of theoretical and practical interest for the needs of agricultural production. InterpreCation and Checking the Condition of Soils in Different Natural - Zones from SpaAe Photographs One of the promising directions in the use of space materials in soil sci- enceis the development of inethods for the quantitative and qualitztive inventorying of soil resources, the development of inethods for the visual- instrunental soils interpretation of space photographs and monitoring the condition of soils. The interpretation of soils was carried out with the use of soil maps at medium and small scales, aerial photographs and materials from field in- ^ vestigations. An analysis of space photographs, based on study of the soilcover of the steppe and desert zones, indicated that using them there is reliable interpretation of automorphous, polyhydromorphous, liydromnrphous, floodplain alluvial and 'irrigated soils. In the steppe zone of Altayskiy Kray and Kazakhstan, on the basis of space photographs at a scale of 1:1,500,000 (and enlarged 4-5X), obtained during the flight of the "Salyut-1" orbital station, there was successful inter- pretation of a number of soils (Table 24) (in the preparation of this table-indicator in our investigations we used materials from a complex geographic interpretation of space photographs for the purposes of special 139 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007102/08: CIA-RDP82-00850R000300050024-7 mapping, work carried out in 1975 at Moscow State University under the di- rection of K. A. Salishchev. An analysis of the table shows that the cited soils are interpreted with a different degree of reliability. Soils with a different participaCion of - solonetz are poorly discriminated from one another on small-scale photo- " graphs. On the basis of absence of plowing of the soils and a lighter photoimage tone it is possible to make an indirect judgment concerning an increase in solonetz in the soil cover. It i.s very easy to see the difference between soddy-slightly podzolic sandy and the main background soils of this territory chestnut and southern chernozems; between ordinary chernozems and mountain chernozems and gray forest soils; between alluvial-meadow and meadow-swampy soils of - low and high floodplains. The data in Table 24 show that using interpretation criteria there is a _ reliable interpretation of ineadow-swampy soils and solonchaks. The photo- image tone of solonchaks is bright white, for solonetz soils light gray, for meadow-solonchak-like soils dark gray, for meadow-swampy - soils dark gray or almost black. In microphotometric measurements of a space photograph of the territory of Altayskiy Kray, on the basis oF i.he nature and shape of the spectral curve there is reliable discrimination of chestnut soils and soddy-podzolic - sandy soils. Sharp peaks of optical density make possible a clear inter- pretation of unconsolidated sands subject to deflation. Areas of chestnut and southern chernozems dif'Ler from one another due to sone decrease (by 0.5-0.7) in the optical density of the latter. Fields with different ag- ricultural crops have a different optical density and in microphotometric ! measurements a characteristic shape of the curve for each field is obtain- ed (Fig. 21). _ A light mechanical composition of chestnut soils (sands and sandy loams) was also determined from the photoimage of the space photograph; sectors of _ soil subjected to wind erosion stand out especially clearly. In a soil-agricultural regionalization of a territory it is possible to use small- and medium-scale space photographs. Using space photographs of the territory of the dry steppe zone of the northwestern part of Kazakh- - stan, obtained during the spring of 1973, we made a study of the soil _ cover. The interpretation criteria for these soils are given in Table 25. An analysis of the characteristics of the photoima.ge indicated that using a space photograph, as a result of its extensive coverage and optical generalization, it was possible to determine the principal soil-geograph- ical patterns of this natural region. - The -2ntire territory, on the basis of the photoimage of the soil cover on a space photograph, was subdivided into five major soil-geographical re- gions. We will noia examine the peculiarities of their photoimage. 140 FOR OFFZCIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY D ' /,2 1,8 I- i I Yh 1.

The space photograph clearly conveys the basic NE-SW trend of the sandy .ridges and interridge depressions and the direction of the nutnerous lakes in this part of the territory. Dark chestnut sandy soils and solonchaks have been formed here. There are sectora of deflatable sandy masses. On the photograph this natural region shows up in a clearly ex- - pressed moire pattern with light gray and gray fones. The solonchaks have an almost.white tone. The transitional sector of lands from the ancient runoff trough to the plateau on *_he apace photograph has a gray and dark gray tone of a large-spotted patterno Dark chestnut solonetz-like, meadow-steppe solonetz and meadow-solonetz-like soils have developed here under virginland wormwood-sheep's fescue vegetation. Thus, on a space photograph of the dry steppe zone during the period of a - spring survey there was reliable determinaCion of: a) dark chestnut cal- careous and meadow-chestnut calcareous soils of plateaus; b) dark chest- nut sandy loam and meadow-chestnut solonetz-like soils of an undulating sandy plain; c) complex soil cover of an ancient runoff trough, repre- sented by dark chestnut solonetz-like, meadow-chestnut solonetz-like and steppe and meadow-steppe solonetz soils; d) amidst the complex soil - cover, on the basis of a light tone, areas of steppe solonetz soils, on the basis of a dark gray tone areas of ineadow and meadow-chestnut solon- etz-like soils; e) eroded sectors of the soil cover, represented by dark chestnut solonetz-like eroded soils and meadow-steppe solonetz soils; f) dark chestnut sandy soils; g) solonchaks. The possibility of interpreting the soil cover of the desert zone from space photographs will be examined on the basis of materials obtained from the "Soyuz-9" and "Soyuz-12" spaceships and the "Salyut-4" orbital station for territories adjacent to Kara-Bogaz-Gol Gulf and also from the American satellite "NOAA-2," which from an altitude of 1,460 km, employing a two- channel radiometer, probes the soil cover in the visible (0.5-0.7e m) and I?t (10.5-12.5 ~ m) spectral zones. A comparative analysis of these photographs, made in the course of our in- vestigations, indicated the following. The photographs taken in the vis- ible and IR ranges clearly show the Caspian Lowland with gray-brown des- ert sandy soils. On the first photograph (Fig. 22, at left) it appears as a nonuniform pattern of a light gray and gray tone with bright-light a.reas of solonchaks in the neighborhood of Mertvyy I:ultuk and Kaydak salinas and in the coastal part of the Buaachi Peninsula.

On the photograph a high percentage of the Ustyurt Plateau hae a homogeneous gray photoimage tone. Gray-brown desert solonchak-like, takyr-solonetz-like, leacbed (elutriated) soils and soils with a high gypsum content are formed here under wormwood-Russian thistle, wormwood-biyurgunova and wormwood- bayalyna vegetation. Uaing space photographs it is easy to see the difference between the soil cover of the Mangyshlakskoye and Krasnovodskoye Plateaus. North of the Kara- Bogaz-Gol, in the territory of the Mangyshlakskoye Plateau, on the basis of the gray and dark gray photoimage tones it was possible to interpret gray-brown desert solonetz-like and solonchak-like, frequently gravelly soils predominantly of a heavy mechanical composition (Table 27). A bright- light tone corresponds to depresaions without external drainage with solon- chaks. On the eroded sectors of plateaus there are exposed bedrocks: clays, limestones, gypsums. On the photograph these places can be detected from the serrated-striated photoimage pattern. These characteristics of the soil cover of the Mangyshlaksk.flye Plateau are especially clearly interpret- , ed from a color space photograph taken from the "Soyuz-12." L. N. Kulesh- ov, et al. (1477) also examined the possibilities of inrerpretation of soils in the territory of the Mangyshlakskoye Peninsula. - The soil cover of the Krasnovodskoye Plateau is characterized by the wide- - spread development of gray-brnwn sandy and sandy loam soils. Here it is ~ common to encounter sectors of hilly and ridged, poorly consolidated and deflatable sands. Takyrs and solonchaks are formed in depressions. A pho- - tograph of the soil cover of this territory shows a mottled spotty-tongue- - like pattern of a gray, light gray and light tone. Difficulties in inter- pretation of the soil cover from space photographs are attributable to the - presence of cloud cover. We made a still more detailed interprztation of the soil cover in this territory from a photograph (scale 1:2,500,000) taken from the "Salyut-4" (Fig. 24, 24a). We will also examine a photograph of the desert zone taken from the "Gev- ini" spaceship and characterizing the photoimage of the soil cover. The _ space photograph (Fig. 25) covers the territory of the Namib Desert ad- jacenr_ to the coast of southwestern Africa. We used a soil map of Africa in its interpretation. 152 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY On the basis of tone and type of photoimage the photograph is clearly sub- divided into three major regions. The upper part of the photograph covers the southern part of tfie Damaraland Plateau and there are mountain red- brown soils of savannas and reddish-brown desertified savannasa The photo- image tone of these soils is gray or dark gray with a characteristic ridg- _ ed-dislocated type of etructure. The middlE part of the photograph has a _ ligbt tone of a uniform pattern typical for the image of gravelly-rocky soils of tropical deserts. The photograph shows a very sharp contrast be- '`ween a sector of granelly-rocky and sandy deserts. The sandy part of the Namtb Desext on the photograph has a gray tone of the photoima.ge and a dune-ridge type of structure characteristic for deflatable and semiconsol- - idated sands. Tfie space photograph shows that the extent of the sand ridges can attain even several fiundreds of kilometers. An investigation of the interpretability of the soil cover from space pho- tographs of the desert zone indicated that due to the good exposure of the soil surface the effect of soil identification in this zone is high. On . space.pfiotograpfis the soil cover of the desert zone is interpreted more pre- - cisely and more completely than for the steppe zone. A space survey makes it possible to monitor the state of soils and their modification under the influence of irrigstion and also identify areas of secondarily saline soils. On space photographs it is rather easy to deter- mine irrigated lands of the semidesert and desert zones from the sharply differing coloration of moist irrigated and dry soils. In the future, using data on changes in the depth of soil and ground water, plans call for de- termining the times for the carrying out of irrigation and the quantity of water necessary for the cultivation of agricultural crops. Using a space photograph (scale 1:1,500,000) taken �rom the "Salyut-1" after considerable enlargement it was possible to distinguish an irriga- tion system from the water intake to the water outlet (Sheyko, 1975). In gart it was possible to see the main canal, along which a dark gray band with rounded (festooned) edges corresponds to sectors with the soil-ground water at a shallow depth. A space photograph at a scale of 1:1,500,000, taken from an altitude of 300 km from the "Gemini-5" spaceahip, clearly shows the fertile old irri- gated lands of the Tigris and Euphrates valleys. The:highly dissected folded limestone-marly chains of the Zagros Mountains adjoin them on the east. A marked periodic increase in the mass of water in the lower reach- es of the Tigris results in floods and the development of a hydromarphou.s landscape with alluvial-swampy and solonchak-swampy soils. On a color pho- tograph swampy areas, have a dark blue color and diffuse, amebalike boun- daries. The dessicated saline bottoms of lakes and swampy sectors are de- termined from the lighter color of the salt crust image on their surfaces. 153 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY A study of the natural wealth.and proper use of river deltas in agricul- tural production is of great importance. River deltas, being some of the recent formations on aur planet, make possible direct observation of the formation of the earth's present-day surface. We determined the characteristic delta structure of alluvial irrigated soils from the next photograph, taken at a scale of 1:700,000 (Fig. 26). This space photograph covers a considerable part of the Nile delta and adjacent territories with sos.ls of tte subtropical deserts. Irrigated soils were represented by a dark gray tone, against whose general back- ground it aras. easy to detect the meandering channel of the Nile Rivero The photoimage of the sandy and gravelly-rocky soils of the subtropical deserts surrounding the delta has a gray and light-gray tone with a char- acteristic complexly dendritic pattern the image of numerous dry wadis. For the territory of Ethiopia, using the photographs it is also possible to determine the soil-plant cover of the valleys and deltas with maximum detail. On a space photograph.of the territory of Central Asia, taken from the "Salyut-4" (scale 1:2,500,000), we interpreted the present-day delta of the Amudar'ya delta, and also with cartographic accuracy, amidst the sands, on the basis of the delta form and pattern of the photoimage of different tonality, it was possible to see several ancient deltas of this river (Fig. 27, 27a)- - On existing soil maps there axe no representations of soil areas of an- cient deltas. With respect to genesis, the soil cover of these ancient delta territories (desert takyrlike soils, solonchaks) is sharply differ- ent from the genesis of the sands surrounding them. With respect to tone, pattern and image contrast on the photographs the sectors of the ancient deltas of the AmLdarlya are nonuniform and differ with respect to age of forma.tion. This makes it possible to detect tihe age of formation of the soil cover of these territories. 154 ' FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOA OFFICIAL USE ONLY Fig. 26.

During a 24-hour period the Soviet system of the "Meteor" artificial earth satellite type is able to take photographs of half the earth. The television cAmeras `of artificia]: ear.th satellites of Che "ITOS-2" type daily transmit up to 140-150 images of the earth�a sur- face. Computations made in the United States show that in a survey from space the entire territory of the country can be represented on 400 photo- grapha. In order to carry out this work it is necessary to have about 17 _ _ days instead of lU years of work with an ordinary aerial survey. The rap- idity of obtaining space materials covering great areas and obtained at one survey time is of great impertance for the comparative study of opera- - ~ tion of irrigation and drainage systems for individual basins and as a - whole for detertaining the nature of the soil cover of different natural , landscapea, etc. 155 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY Fig. 27.

The reliability of interpretation for di�- ferent crops was different. For example, fields with perennial grasses = are interpreted reliably from tfie dark gray, almost black tone, the rec- tangular form of tfie units with distinct boundaries and a homogeneous pat- tern. Grains (wheat, barley, oats) have a similar gray image tone. Fields with grain crops are clearly interpreted on a plain and somewhat less clearly in the foothill zone, where with reapect to phototone they merge _ with mountain pastures. Fields with corn show up in a dark gray tone but - are not always interpreted because with respect to photoimage they are - close to pastures. Fa.l?:ow fields, having a light gray tone, of a homogen- eous or spotty structure, are reliably ir_terpreted, but with reapect to - tone coincide with the generalized photoimage of solonetz soils. In carrying.out our investigations from a space photograph of the terri- tory of Northwestern Kazakhstan with dark chestnut calcareous and meadow- chestnut calcareous soils it was possible to determine the nature of agri- cultural worki-77 of the fields. The survey was carried out on 30 April 1973 prior to 'crc carrying out of spring field work over this territory. Accordingly, the different working of the soils in 1972 was reflected on the photographs. Ninety-four fields were subjected to visual-instrumental interpretation using a"Kvantimet-720" image analyzer and subjected to field checking. On the basis of the different photoimage tone (Table 29) for the soil sur- face it was possible to have reliable discrimination of fields in which there was bare fallow during 1972. These fields accumulated the greatest quantity of moisture during the sumcner-autumn period of 1972 and the early spring period of 1973 and on the photographs appeared in a gray tone (av- erage level of the gray tone 36-41). A light gray tone (39-44) was char- acteristic of fields in which during the autumn Chere had been deep loos- ening of the soil to 25-27 cm. During the autumn and early spring periods these fields also accumulated considerable quantities of moisture, but less than in fallow sectors. A light tone (43-48) corresponds to fields in which in the autumn of 1972 there was scuffling by cultivators-cutters to a depth of 8-12 cm. Final- = ly, the lightest image (46-52) on space photographs was characteristic of space photogr aphs of unworked fields in which the stubble of grain crops y' remained in sutumno In an analysis of the photoimage of the two latter fields it is necessary to take into account not onl.y the nature of the moistening, but also the state of the soil surface (rough, smooth) and especially the presence of stubble on its surface. On space photographs at a scale 1:2,500,000-1:1,000,000 taken from the "Salyut-4," on the basis - of different tone we reliably determined plantings of agricultural crops. In the territory of the Saratovskoye Povolzh'ye, where three farms were subjected to field checking and 146 fields were taken into account, from a srace photograph for the summer survey period (June) it was possible to discriminate the following sown areas and land uses. A light, almost white photoimage tone was characteristic of infrequent fields with plant- ings of winter rye and winter wheat; light gray tone corresponded to 158 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY fields with melon crops and fields with three-level plowing of the soil; gray tone corresponded to spring wheat, Taarley, oats and grazing sectors; dark gray tone corresponded to corn, sunflower and alfalfa; on the photo- grapha an almost black tone corresponded to irrigated alfalfa and forested sectors. - On space photographs of the steppe zone of the Ukraine (Khersonskaya Ob- last), where two farms were field checked and 137 fields were taken into account, the following crops were determined for the summer survey period. A light, light gray tone corresponded to numerous fields of winter wheat; a gray tone corresponded to spring craps (barley, oats) and sectors of . pasture; a dark gray tone corresponded to corn, sunflower, alfalfa and sectors of clean fallow; fields with irrigated alfalfa corresponded to an almost black tone of the photoimage. A comparative analysis of the photoimage of agricultural crops on space photographs (same survey season) of these two soil-geographic regi_ons of the steppe zone of the European territory of the country indicated their similarity. With the avaiTability of a small number of key sectors this - makes possible a routine and rel.iable determination and prediction of the - types and state of development of the main agricultural crops from space ' photographs for a definite soil-agricultural zone. - In two space polygons in the United States, located in South Dakota and Arizona, the problems involved in the interpretation of sown areas and their condition is the emphasis of a scientific program in the field of agriculture. For example, in the South Dakota polygon the materials from joint surface investigations, aerial survey data and data obtained from space satellites or orbital stations (of the ERTS and "Skylab" types) have been used for the following purposes: a) estimation of the yield of agri-- _ cultural crops; b) estiraation of the productivity of pastures for domea- tic cattle; c) establishing a relationship between soil fertility, moisture - content and local topography. On one of the space photographs of the Imperial valley in California (in the United States), taken during flight of the "Apo11o-9" spaceship on 12 March 1969 from an altitude of 240 km for the purpose of studying re- sources and-including for the identification of soils and agricultural land use in the territory of the Unite:d States and Mexico, the agricultural irrigated fields have a bright red color on the photograph in the United ~ States, bat similar territories in Mexico with a high percentage of idle and saline lands with a reddish-greenish-dark blue color. Agricultural fields of the irrigated Imperial valley show up most cleaxly and graphically. Depending on the type of agricultural crops the fields show up in a red color (from light orange-red to blue-red). Sugarbeet and alfalfa fields not yet harvested at the time of the survey appear in a bright red color._,Groves of citrus crops are eharacterized by a darker red "muffled" Cone. A`,light blue and bluish-green hue corresponds to fields of 153 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 harvested cotton. On the photograph, in an irrigated zone amidst the ag- ricultural fields, it is easy to see dams, water bodies, main and secondary irrigation canals. - One of the important characteristics of use of space materials for agricul- Cural purposes is the possibility of a rapid repetition of the survey. This protilem is successfully solved by employing photoelectronic space methods for collecting information on soil-agricultural phenomena. The r.outineness of space information is important for judging rapidly develop- - = ing dynamic processes transpiring at the earth's surface. For the first time by means of repeated surveys from space it was possible to judge simultaneously the nature of snow melting over enormous areas of the - earth and the development :--F the processes of erosion and distribution of _ - seasonally and repetitivaly sasine soils. The routine data regularly received from artificial earth satellites are es- ; pecially necessary for determining the condition of agricultural fields, for checking plant diseases and the distribution of pests afflicting ag- ricultural crops, as well as for determining the areas of dead crops and ffeld weediness. The availability of routine space information on the phases of development , and condition of agricultural crops will make it possible to predict their yield and make a more precise determination of the calendar plan for carry- ing out agricultural work. American specialists feel that due to the differences in the image of plant- _ ings of different crops (soy beans, corn, winter wheat, rice, cotton, etc.) _ ERTS photo$ranhs have potentialiti_es for routine computation of the _ yield. For this purpose a semiautomated system for the processing of space : photographs is being developed for the solution of agricultural problems. 160 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-00850R040340050024-7 - FOR OFFICIAL USE ONLY - Chapter 6 CHARACTERISTICS OF INTERPRETATION OF SOILS AND SOWN CROPS FROM MULTIZONAL AERIAL PHOTOGRAPiiS The use of multizonal photographs has now been initiated in the search for an increase in the information capacity of aerial and space materials _ for the study of natural resources, including the soil cover and agri- cultural cro?s. This type of survey is based on obtaining an image of the soil cover and agricultural crops simultaneously in several narrow - spectral zoxaes. As a result, for soil and agricultural interpretation as interpretation criteria it is possible to use the differences in spec- - tral brightn2ss of different soils and agricultural crops. In the visual-instrumental interpretation of multizonal photographs use was made of the following elements of the image of soils and sown crops: _ 1) spectral (di.fference in image tone different spectral zones); 2) . textural (distribution of tonal variations within the limits of one zone); 3) landscape (relationship between soil characteristics and the environ- ment). A study and registry of these image elements, especially the first = two, will make it possible in the future to approach the machine process- ing of photographs. _ It is possible to obtain images by detectors having diff erent spectral re- sponse in the optical, thermal and radio ran.ges of the electromagnetic spectrum. However, during recent years a multizonal survey in the optical - range in the visible and near-I.R spectral regions has been developed to ~ the greatest degree. In our country in the mid-1930's the studies of V. A. Faas (1936) laid the _ basis for'a multizonal survey. Later fundamental investigations in the = - spectral ciassification of different natural features, including soils, - were made by Ye. L. Krinov (1947). An important stage in the development of a multizonal survey was the worlc of A. N. Iordanskiy (1967) for creat- ing a series of sppctrozonal films. A considerable influence on the de- - velopment of a multizonal survey of the earth's surface was exerted by � the work of the Aerospace Methods Laboratory of the Geography Faculty Moscow State University, where the first special multiobjective survey _ - camera was constructed in the late 1950's. 161 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 Multizonal scanner systems appeared later. In 1973 a multispectral scann- = ing system (riSSS) and a digital videorecording unit were employed in the _ study of naCural resources (Khodarev, Avanesov, et al., 1974). The "Foto- skaner-4" was used in the surveying of geological features; it operates _ in the ultraviolet, visible and infrared spectral zones (Apostolov, Seli- . vanov, 1974). - The use of multizonal materials is affording additional new possibilities for a more complete and objective interpretation of the soil cover and plantings of agricultural crops. Various studies (Andronikov, 1976, 1979; Andronikov, Sinitsina, Shershu- kova, 1975, 1977; Afanas'yev, et al., 1978; Vinogradov, 1976; Vinogradov, - Glushko, 1976; Garelik, eC al., 1976; Zonn, 1977; Knizhnikov, Kravtsova, 1976; Labutina, Chechneva, 1976; Miroshnichenko, et al., 1977; Tolchel'- - nikov, Chukov, 1977) examine the problems involved in the use of multi- - zonal photographs for the study of natural resources, including for the _ icientificatton of soils and agricultural c�rops. - _ As an interpretatiou criterion for multizonal images in a microphotometric analysis use is made of both the absolute optical density and the differ- _ ence in opCical densities, measured at the boundary of two adjacent fea- tures. In this case the basis for a successful interpretation of soil-ag- ricultural features is the different degree of expression of their boun- dary contrast on photographs taken in different zones of the electromag- _ netic spectrum. The absence or poor (unreliable) presence of a boundary _ contrasC on the films of one zone and its appearance on films of other - spectral zones considerably increase the reliability of interpretation of soils and a;ricultural crops, inc?uding such an important index as yiel d. The possibility of determining agricultural crops and soils wus compared for the territory of the United States using IR color and multizonal. _ black-and-white films. The correct identification of alfalfa fields from , color infrared films was 70%, when black-and-white films were used - 40%; for barley fields the corresponding values were 69 and 62%; for sugarbeet fields 70 and 90%; for plowed fields 64 and 82%; for saline soils (solonchaks) 67 and 89% (Leamer, Weber, Wiegan', 1975). - A multizonal aerial survey of the soil cover was made in southeastern Eng- land in four spectral ranges from blue-green (0.4-0.5 m) to IR (0.7- 0.9~m) at a scale of 1:15,000.

Interpretation of Multizonal Aerial Photographs of Stepps Zone - The territory of an experimental sector oP tlie Central Russian Highland ~ was a reference area for the stepps zone in which the testing of aero- - s-oacP methods for the study of soils and agricultural crops was carried - out. This sector was selected as an experimental area for study of nat- ural and anthropogenic geosystems of the central part of the wooded steppe on the Russian plain (Gerasimov, Grin, 1976). At the present time all the lands convenient for agriculture in this zone - are cultivated (cultivated area more than 70%) and the natural vegetation of the meadow steppe has been preserved only in-individual sectors with ad- j acent forests. The relief of t�e investigated territory of the Central Russian Highland is erosi.onal. The water divides have a slightly convex surface. The - ravines are sodded. The soil-forming rocks are represented by calcareous loess-like pulverized clayey loams. The soil cover consists o.f thick cher- _ nazems which can be assigned to typical aad leached subtypes and meadow- cher.zozem soils. Typical and leached chernozems have the widest occurrence on the water divide plateaus and slopes and replace ane another at close distances. Calcareous excavated chernozems hillflcks at the mouth of marmot burrows occur widely. Podzolized chernozems are rarely enr.oun- - terpd and are developed in the upper part of gullies and ravines where the soils rec2ive additional moistening. Headow-chernozem soils are asso- ciated with microdegressions and the bottoms of steppe ravines. Alluvial meadow, moist meadow and meadow-swampy soils are formed on the floodplain of the Seym River. In 1973 a multizonal aerial survey of this territory was carried out i.n the second half of September when $rain fields were harvested and sprouts of winter wheat appeared and a great number of fields were free of sown crops. Among the different survey zones of the electromagnetic spectrum, in the interpretation of 1973 we used the green zone with sensitivity mazima at (520 nm), yellow-green (560 nm), red--urange (610 nm) and near- IR (840 nm). Three zones were selected for subsequent analysis: green, red, - IR, having the greatest contrasys with one another in the image of soils and sown crops. Data from visual-instrumental interpretation of the soil cover, principal agricultural crops and virginland vegetatiori from multizonal photographs (Fig. 28, A, B, C) are given in Table 30. 163 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 _a Fig. 28.

Against the image background of winter crops (sprout- ing phase) meadow-chernozem soils in depressions were successfully inter- preted from photographs in the green and also in the red spectral zones. On the floodplains of steppe rivers on the basis of the image of ineadow and meadow-swampy vegPtation in all spectral zones it was gossible to interpret alluvial meadow and meadow-swampy soilsa - The it:terpretability of agricultural crops (difference in levels of gray tone of individual fields) is different for different spectral zones. The sharpest difference between winter crops (sprouts) and sugar beets can be seen in the IR zone (41-47 units versus 3-10 in the remaining spectral ~ zones). This pattern, but with a lesser contrast, is characteristic for _ f ields of corn, millet and perennial grasses. The photoimage of wtnter crops (sprouts) is characterized by a gray image tone in the red and green spectral zones and an alsa st black tone not dif- = fering from the image of plowed soils in the IR zone. Sectors of viiginland vegetation (virgin steppe) were reliably determined - on photographs in the red zone an the basis of a light gray tone, whereas the steppe, after hay mowing, is characterized by an almost white tone (similar to the image of sugarbeet fields) in the IR zane of the electro- - magnetic spectrum. In 1974 a multizonal aerial survey was carried out in the late autumn per- iod in mid-October. This is the time of maximum plowing of the fields and development of winter crops (tillering phase). Data from a visual- instrumental interpretation of the soil cover, agricultural crops and - virginland vegetation are given in Table 31. In 1974 a survey was made in four spectral zones: green (520 nm), red (610 and 690 nm) and IR (840 nm). The red zone photographs ha3 a unifoxm image and the-zone 690 nm re- mained for analysis. J The surface of plowed typical and leached chernozems with small variations (be these fields with fields of grains or cultivated crops) shows up in a _ dark gray tone in the IR and in a gray tone in the red spectral zone. On photographs in the red, and to a lesser degree in the green zone, it is possible to see a�ine �'point" spottiness of a light gray tone which is associated with the photoimage of excavated calcareous soils. Another type of fine spottiness of an almost black (dark gray) tone is character- istic for the image of ineadow-chernozem soils in microdepressions. Such spottiness does not appear on photographs in the IR zone. In addition, on the basis of a light gray image tone on IR photographs it is possible to interpret the appearance of weeds in fields. Whereas in this zone the difference in the level of the gray tone between fields with and without weeds is 7-11, in the red zone it is 1-2 and in the green'zone is 2-6. 167 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY ~ i ~ r-I CO M bO w 4-4 N JJ H O ~ 'd 'O ~ a w a a i 0 a) o rl ~t U ,C 44 N ci o 10 0 r. 3 cd o 41 ,n m v a. w 1+ ~ ca (d bo 4 o ~ oo cV %O y+ O f 1-' r i ~ .C H 00 � .

In the IR zone an almoat white tone - corresponded to �unharvested fields of fodder beets. Differences in the photo image of ineadow-s~eppe vegetation of steppe ravines with meadow- chernozem soils and meadow-swampy vegetation with alluvial-meadow and meadow-awampy soils are interpreted better from photographs in the red zone and considerably poorer in the IR spectral zone. _ One of the principal results of carrying out a multizonal survey in late - autumn (October) is the possibility of: a) a more detailed analysis of the soil cover; b) determination of the level flf development of winter crops and prediction of their yield for the next year. In 1975 a multizonal aerial survey was carried out twice: early in the sum- mer (S June) and a month later (9 Ju1y), This was a period of intensive growth and development of agricultural crops and the first half of July was the beginning of harvesting of winter crops. As indicated by an an- alysis of summer photographs, at this time there is virtually no open surface of the'soil cover and soil interpreta'cion is accomplished through the direct image of agricultural crops. The interpretability of soils in different spectral zones and through different crops ls different (Table 32). = On the June photographs in the green and red zones through the photoimage of sugarbeets, having a light gray tone, it was easy to interpret meadow- - chernozem soils (Fig. 30). They show up as fine dark dots (in the formation of so ils in swales) and dark striations (in the case of formation of inead- ow-chernozem soils in longitudinal troughs). Similarly, on June photo- _ graphs it is possible to interpret meadow- cherno zem soils successfully amids t typical and leached chernozems through the direct photoima.ge of fields of corn and potatoes. In the IR zone they are not interpreted or - are determined with greater difficulty. Accordingly, during early summer through the photoimage of cultivated crops against the background of cher- nozems there can be reliable interpretation of ineadow-chernozem soils in the red and green spectral zones. On July photographs this possibility is lacking in all spectral zones. By mid-summer cultivated crops are well- developed and completely mask the soils. In addition, an analysis of the July photographs indicated that meadow- chernozem soils, formed in swales and longitudinal troughs, are inter- preted on photographs taken in the green and red spectral 2ones through a planting of spring wheat with an undersowing of clover and especially through a planting of vetch. In a field occupied by vetch it is easy to - see the dotted-striated soil cover structure. The data in Table 33 show that the greatest differences between chernozems and most agricultural crc: ;P, are observed in the IR zone. - 172 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY _ On the June photographs (see Table 32) from the photoimage of winter wheat in the green and IR spectral zones it was poasible to determine the dif- ference in the yield of wheat sown on bare fallow 40 centners/hectare - and wheat sown nn occupied fallow (peas) 25 centners/hectare. The dif- ference in the levels of gray tone between wheat with yields of 40 and 25 centners was 10-15 units. In the red zone it could virtually not be dis- cerned at all. At the same time, it was established that on the photoim- age on multizonal aerial photographs obtained in all three spectral zones during this moni;h plantings of winter wheat with a high yield are similar to sectors of ineadow-steppe vegetation, sown perenn3al grasses, as Wei1 as fields of spring wheat and barleq with an undersowing of perennial grasses. The investigations indicated that for the reliable identification of agri- cultural crops a change in their photoimage in different spectral zones in dependence on survey time is of great importance. For example, spring - wheat and barley from June to July change tone on photographs in the red zone from dark gray, almost black, to light gray, almost white, whereas cultivated crops (sugarbeets and corn) vary from light gray to dark gray. However, images of ineadow-stepp e and meadow-swampy vegetation, and also forests, do not experience sharp changes in tonality on photographs from June and July surveys. For mid-summer (July) we made a comparison of the - photoimage, of the surface of the analyzed steppe sector, obtained syncliron- ously on multizonal aerial photographs and a space photograph. A compar- _ ative analysis of the photoimage indicated that with respect to tone ag- ricultural crops, forest and soils on a space photograph are similar to the same features on an aerial photograph taken in the red zone. Accordingly, the interpreted aerial photographs for one and the same survey time (in the limits up to two weeks) and photographs from space can serve as a "key" for the interpretation of space materials. In conclusion we will give a siTmmarized table-key for the interpretation af the principal soils (Table 34) in an experimental sector of the steppe zone which we compiled on the basis of a soil interpretation of multizonal aerial and space photographs. In working up this table-key we used data on soil-forming factors (relief, vegetation, soil-forming material), phys- ical and chemical properties of soils, exerting an influence on their re- flectivity, and have indicated the soil interpretation criteria. 173 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 Interpretation of Multizonal Aerial Photographs of Dry Steppe Zone A study of the soil cover and plantings of agricultural crops of the dry steppe zone from aerospace photographs was made in the territory of one of the experimental sectors in Northwestern Kazakhstan. In physiographic respects the analyzed territory covers the southern part of the West Siberian I.owland the Turgayskaya "tableland" country. The ~ northern part is situa.ted within the limits of an undulati.ng sandy plain and the southern part is situated within the limits of an extensive plat- eau. In geobotanical respects this zone is a dry steppe with a predomin- ance of feathergrass-sheep's fescue-mixed grasses, feathergrass-sheep's fescue-wormwood associations on dark chestnut soils and sheep's fescue- wormwood-goldilocks associations on solonetz soils. The territory has a lowland relief. In geomorphological respects it is _ possible to discriminate northern, central and southern parts in the con- sidered region. The no rthern part is a slightly undulating sandy plain, complicated by numerous mesodepressions, frequently occupied by bitter- saline lakes. The lakes are slightly incised, with flat bottoms. The ex- panses between the lakes are flat, sometimes slightly convex water div- ides with gentle slopes (1-3�) of different length and exposure. The soil-forming rocks here are unconsolidated sandy and sandy loam Quat- ernary deposits underlain by a Paleogene sandy-pebbly stratum. The soil cover of the northern part of the considered territory is represented by dark chestnut sandy lo am soils on the water divides, meadow-chestnut soils in depressions and sma.ll contours of solonchaks around bitter-salt lakes. Due to the light mechanical compoeition most of the lands in this part of the territory are not plowed and constitute a sheep's fescue-feather`grass- crested wheatgrass idle land or a virgin land with sheep's fescue-feather- grass-mixed grass and feathergrass-sheep's fescue-wormwood associations. The central part of the lands of the experimental sector is an ancient runoff depression. This is a slightly undulating plain complicated by numerous forms of ineso- and microrelief in the form of microdepressions, remanent hill's, ridg es, modern runoff troughs with intermittent water- courses. The soil-forming rocks here are represented by saline clayey loams, Tertiary variegated saline clays, in which the prQSence of micro- crystalline gypsum is discovered beginning a.t a depth of 60-80 cm. Aleuritic rocks partic ipate in soil farmation in individidual remanent hills. In the soil cover here there is widespread occurrence of solonetz, chestnut and meadow-chestnut soloi-ietz-like soils (Figures 31, 31a). The southern part of the territory occupies an extensive plateau. In its cenl-ral lowland part there is extensive devel9pment of flat microdepres- sions and microhills of zoogenic origin hillocks formed at the mouth. - of marmot burrows, creating a microcomplexity of the steppe surface.

The soil cover is very homogeneous and is represeitted by dark chestnut and dark chestnut calcareous excavated soils (mirmot hillocks) on the plateau and calcareous meadow-cr.estnut soils in microdepressions = (Figures 32, 32a). This territory.is the principal cultivkited land re- _ source of the farm. Among the agricultural crops here there is a predom- inance of plantings of spring wheat and barley. In the central part a high percentage of the cultivated land is occupied by plantings of per- ennial grasses (crested wheatgrass). _ In 1973 a multizonal aerial survey was carried out in the green (520 nm), red-orange (610 nm), IR (840 nm) spectral aones at the end of July, 60-70 _ days after the sowing of grain crops spring wheat and barley. On the - territory of the plateau on dark chestnut calcareous and meadow-chestnut calcareous soils these crops form a dense cover and cover the soil sur- face. In this case the interpretation is ma.de through the photoimage of the agricultural crops. ' On the territory of the plateau through the photoimage of spring wheat and barley in the red spectral zone there is reliable discrimination of dark chestnut and meadow-chestnut soils; in the green and infrared zones = they differ slightly (Table 35).. Dark chestnut calcareous excavated soils _ (marmot hillocks) are not masked by plantings of grains; in the green and especially in the red zone they have a bright-light tone (50-62); these soils are not interpreted on photographs in the IR zone. _ On the photograph the fields occupied by spring wheat and barley have a - diff erent tonality, well expressed in the red and SR zones and poorly ex- _ pressed in the green spectral zone. These differences in overall tonality are attributable to a nonidentical yield of spring wheat and barley. - Now we will examine a sector of the territo ry of an ancient runoff trough with a varied complex soil cover. The analysis shows that in the red zone through fields of spring wheat there is clear interpretation of dark chestnut solonetz-like soils, meadow-chestnut solonetz-like and meadow - solonetz-like soils. Steppe and meadow-steppe solonetz soils have sim- - ilar photoimages, but differ clearly with respect to their position in - the relief. In the green zone such a field has a lsss contrasting photo- image. In the IR zone a field of winter wheat witha complex soil cover has very weak contrasts. For examvle. whereas in the red zone the differ- ence in the level of the gray tone between meadow-chestnut soils and solonetz soils attains 24 units, in the. IR zone this difference is 3. An = exception is the meadow solonetz-l ike soil, which is reliably interpreted in the IR zone from the light tone of the photoimage. From the photoimage of corn in the IR zone it is easy to see the difference = between fields with a different sowing time.

Soi1s: 1) dark chestnut calcareous, medium-thick.zess, clayey and dark chestnut excavated (hillocks at mouths of marmot burrows white dots on photograph) soils; 2) meadow-chestnut calcareous clayey soils. For example, the difference in the level of the gray tone for an earl.y sow- ing time between the above-mentioned soils in the green zone is 5 and 6 units respectively, in the IR :;one 6 and 8 units, in the red zone 12 and 18 units. On photographs in bare fallow, if it is well worked and not overgrown with weeds, the surface soil horizon shows up directly. Against the background of surrqunding fields and crops sectors of bare fallow show up most clear- ly in the IR zone. In the re.d spectral zone against the general tone of the photoimage they differ slightly from fields occupied by plantings of spring wheat and perennial grasses or virtua.lly do not differ from them. However, within fieids of bare fallow the interpretability of different soils is most sharply expressed on photographs taken in the red spectral zone. The difference in the level of the gray tone in this zone (reliabil- ity of interpretation) for dark chestnut solonetz-like and meadow-chestnut solonetz-like soils is 12, between dark chestnut solonetz-like and steppe solonetz soils is 10, between meadow-chestnut solonetz-like and solonetz soils is 21. The soil cover of the dry steppe zone is successfully interpreted through r~ glantings of perennial grasses (cre.sted wheatgrass) and the Photoimage of virginland vagetation. For example, through fields of crested wheatgrass dark chestnut sanciy loam and light clayey loams in the red zone were APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 reliably discriminated from meadow-chestnut and especially meadow-steppe solonetz soils. Through the virginland vegetation it was possible to de- termine meadow-chestnut solonchak-like soils, meadow-mixed and complex soil units consisting of ineadow-chestnut and meadow-steppe solonetz soils and sectors of ineadow solonchaks. Accordingly, in the dry steppe zone, using suumer July photographs taken _ in different spectral zones, the soil cover is successfully interpreted through the direct images of spring xaheat, barley, corn and perennial orasses. This is attributable to the fact that with average harvests in _ the arid years agricultural c�rops did not mask the differences in the soil cover, but on the contrary, emphasized them. It is possible that in moist years this effect w:Lll be different. Another important conclusion uhich can be dra-,an on the basis of an analysis of the photoimage of multizonal photographs is that in the case of a uni- - form soils cover (on dark chestnut calcareous clayey soils of extensive plateaus) on the basis of the difrerent tonality of one of the leading crops spring wheat it is possible to ascertain its crop yield. - Among the spectral zones the best results in the interpretation of the soil cover and agricultural crops were obtained in the red zone. Photo- graphs taken in this`zone clearly show dark chestnut calcareous, meadow- chestnut calcareous and dark chestnut calcareous excavated (at mouth of marmot burrows) soils of plateaus; there was reliable inrPrnretation of the complex soil cover with solonetz in the central part of the lands in the territory of an ancient runoff trough; tonal differences between plantings of spring wheat, barley and chick peas were noted better than in the green and IR zones; it was easy to interpret perennial grasses and the soils beneath them. In the IR and green zones these differences were appreciably weaker or there were none. An exception,is the photoimage of bare fallow and planti.rigs of corn sown at different times (with different ' projective covering), which in the IR zone showed up with the greatest contrast. In autumn, in mid-September 1973, a repeated multizonal aerial survey of _ the soil cover and agricultural crops was carried out at a medium scale in the green (520 nm), red-orange (610 nm) and IR (840 nm) spectral zones. It coincided with the period of harvesting of grain crops. Therefore, some of the fields at the time of the survey had already been harvested and the photogra�phs showed the stubble of corn and grains on which the soils were being worked with cultivators-levelers. In individual fields it is pos- sible to see spring wheat and barley in the phase of gold ripeness. An analysis ofthe characteristics of interpretation of the soil cover and _ agricultural crops during the autumn survey period indicated the following (Table 36). In the red anc', IR spectral zones there was reliable discrimin- atior: of fields of sPring wheat with a yield differing by a factor of 2- 2.5 on dark chestnut calcareous soils. In the green zone these differences did not exist. 178 " FOR OFF~CIAL USE ONLY m APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 ~ FOR OFFICIAL USE ONLY In sectors of bare fallow with a direct representation of the soil surface on the photographs in general th.ere is a greater brightness of the photo- - image of the soil cover (especially solonetz soils) associated with drying out of the upper soil horizon azid possibly a greater drawing-out of carbon- _ ates td the surface. In comparison with the summer survey period, in autumn dark chestnut and meadow-chestnut soils are diff icult to see under corn in the green and red specCral zones; in the IR zone they cannot be seen. On the other hand, meadow-steppe soils can be seen considerably more sharply (except in the IR zone). This is attributable to the fact that on solonetz soils there is - virtually no corn and on the photographs it is possible to see the light surface of the solonetz 5oils, whereas on dark chestnut and meadow-chesfinut soils corn has a well-developed leaf su-rface which shows up in a dark gray tone. The soil cover can be interpreted through corn stubble c+nly in the IR spectral zone. Durino the autumn period meadow-chestnut soils are slightly distingu:ishable through fields of perennial grasses with dark chestnut solonetz-like soils and solonetz soils, especially in the red zone, can be interpreted very clearly. In 1974 a multizonal survey in the green (540 nm), red (690 nm) and IR (840 nm) spectral zones was carried out in early July, 1-1.5 months after the souring of grain crops. The survey was made on a medium scale. On these photographs on the basis of the different pnotoimage of the grain crops it was easy to see the difference in the moisture supply of the soils, related to their different working. For example, with the sowing of spring wheat at one and the same time (25-26 May, dark chestnut calcareous soils) on photographs in the red and IR 9pECtral zones there was reliable interpret- at3,on of the difference between fields in which in 1973 there had been deep loosening of the soil (to 25-27 cm), and in the course of 1971-1973 , there had only been a''plowing-under of the stubble (to a depth of 8-12 cm) ('Pable 37). Among fields of barley (dark chestnut calcareous soil, sown 29-30 May) a different tone in the IR zone was characteristic ot fields in which there had been bare fallow in 1972, whereas in 1971-1973 there had been plowing-under of-the soil. In autwnn the yield ori.these soils was 12.0 and 8.5 centners/hectare respectively (Fig. 34). On the photographs it was possible to discriminate fie_,:'s with different times for the sowing of spring wheat (15-16 May, 25-30 May, dark chestnut calcareous soils). Fields sown at different tiiAes with the best develop- menr flf wheat had a darker gray photoimage tone in the red and a lighter gray tone in the IR spectral zone. Dark chestnut calcareous and meadow-chestnut calcareous soils, dark chest- nut solonetzlike, meadow-chestnut solonetzlike, stieppe and meadow-steppe solonetz soils, meadow mixed and meadow solonchak soils were reliably in- terpreted through plantings of grains (spring wheut, barley, millet), - 179 FOR OF','!;T.CT.,I, USE.

In fields where perennial grasses had been mown the interpretability of soils was ~ poor and only areas of ineadow-chestnut soils could be seen. _ On phoCographs in the IR spectral zone against a background of agricultural plantings it is very easy to interpret fields with sectors of bare fallow, but internal differentiation of the makeup of the soil cover in them was poor (Fig. 34). Photographs in the green spectral zone do not give additional new informa- - tion concerning the soil cover and agricultural crops in comparison with the photographs just considered. With respect to the nature of the photo- image they are close to photographs in the red zone, but for a number of soil-agricultural features have a less sharply expressed contrast. In 1975 a multizonal survey in the green (540 nm), red (690 nm) and IR (840 nm) spectral zones of the experimental sector was carried out in mid-June. ' With respect to moistening conditions in the territory of Kazakhstan this year was acutely arid. On the photographs, from the state of development of plantings of winter wheat on dark ehestnut calcareous soil-in the course of the first month,it can be seen that the phutoimage is influenced consid- erably by the presowing working of the soil. With one and the same sowing times. and soil conditions the best development of spring wheat was noted in fields where the presowing working of the soil was carried out with the - KPE-3.8 antierosion cultivator to a depth of 12-14 cm and sowing with the _ SZS-9 drill in comparison with fields where sowing was carried out with the SZS-2.1 drill. These differences were observed most sharply on photo- - graphs in the IR spectral zone. The difference in the level of the gray tone of these fields in the green zone was equal to zero, in the red zone 2, and in the IR, which was most sensitive to the development of plants 12 (Table 38). On early sumzner photographs in the green and eapecially in the red spectral _ zones the soil cover was reliably.-:interpreted through plantings of spring wheat, barley, annual and perennial grasses. Over the territory of plateaus - it was possible to determine meadow-chestnut soils through plantings of spring wheat against a background of dark chestnut calcareous soils on the basis of a dark tone and affinity to swales; the image of small light dots was indicative of dark chestnut calcareous excavated soils (at the mouth of marmot burrows). In the red zone these soils had a more sharply expressed contrast than on photographs ir. the green zone. In the IR zone the excavat- ed soi]s at the mouth of marmot burrows could not be detected, whereas meadow-chestnuC soils appeared in a light gray tone similar to the general image background of fields covered with cultivated vegetation. - The complex soil cover of the centxal part of the territory to be analyzed, oc�.,.ipying the dncient runoff valley, could be seen in detail through plant- ings of barley and annual grasses (foxtail millet) on photographs in the 180 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 ' FOR OFFICIAL USE ONLY green and IR zones, but with special contrast on photographs in the red spectral zone. Fielda of freshly plowed bare fallow showed up in all the analyzed zones, but especially sharply in the IR. On fallow, from the direct image of the soi1 surface, on photographs in the red and green zones it was easier to interpret dark chestnut calcareous, dark chestnut calcareous soils excav- - ated at the mouth of marmot burrows and meadow-chestnut soilsa In all spec- tral zones on the basis of a light gray tone there was reliable discrimin- ation of unworked fields in fallow, covered by solonchaks. Against the im- _ age background of these fields on the basis of a dark gray tone there was a clear interpretation of ineadow-chestnut soils (especially in the red zone). In the IR spectral zone these soils had a light gray tone similar to the general image background of fields covered with weedy vegetation. Through ci.xJ_tivated crops (corn fields) the soil cover was readily inter- preted from photographs in the red spectral zone: sandy loam and light - clayey loam dark chestnut soils, solonetz-like meadow-chestnut soils and meadow-steppe solonetz soils were discriminated; in the green and IR zones soil differences were poorly visible tihrough corn fields (solonetz soils) or the soils cannot be interpreted (for example, meadow-chestnut soils). Through plantings of perennial grasses (crested wheat grass) on early sum- - mer photographs the complex soil cover (dark chestnut solonetz-like, mead- ow-chestnut solonetz-like and meadow-steppe solonetz soils) showed up very - sharply in the red spectral zone. In the green zone the soils are visible but the image contrast is poor. In the IR the soils are not interpreted; the field has a homogeneous light gray co].or. Some lightening of the tone can be noted only in solonetz areas. ' The soil cover shows up most differentially on photographs in the red spec- tral zone through virgi.nland vegetation. In particular, this differentia- tion is associated with a detailed representation of ineadow-chestnut soils asaociated with microswales ar.d longitudinal troughs. In the green and IR _ spectral zones these soils are virtually not interpreted or can be seen very poorly. On early summer photographs in the green, red and IR zones meadow and weedy _ solonchaks are shown in a similar (light or almost white) tone. Accordingly, for the purposes of objective and reliablE interpretation of the soil cover, agricultural crops and virginland vegetation in the terri- tory of the dry steppe in the early summer period it is necessary to use aerial photographs taken in the red (primary) and IR (secondary) zones. IR photographs were particularly yaluable material in an analysis of dif- ferences in the state of agricultural crops (for example, spring wheat) during initial periods of development of grain crops (tillering and -I ].81 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 stem extension stages).

In pilotoelectronic methods for the registry of t1.ie soil-vegetation cover use is made of multispectral scanning systems (MSSS) radiometers, side- view radars and other photoelectronic instrument's. Using these methods in- formation on soils and agricultural crops can be registered on magnetic tape or registered in the form of an image on the screen of a cathode ray tube. Photoelectronic methods can be used in the W(0.01-0,4 � m), in the entire visible zone of the spectrum (0.4-0.76), in the near-IR (0.76-1.1 w m), in the far IR (1.2-25tkm) and in the radiowave spectral region (from 1 mm to several meters). Using photoelectronic methods it is possible to obtain new additional in- formation on soil-agricultural resources in comparison with aerial photo- graphic methods. This occurs, on the one hand, due to a survey in those parts of the spectrum which are not employed for photography on light- sensitive materials (the sensitivity limit for infrafilm is 1.1 jAm); on the other hand, this is due to the use of narrow spectral zones for sur- veying of the soiZ-vegetation cover with a considerably greater differen- tiatinn on the basis of their spectral brightness. At recent congresses of the American Photogrsnmetric Society much atten- tion has been devoted to the problems involved in interpretation and new photoelectronic technical means for obtaining information on the earth's surface. The attention of researchers in this field is being given to ob- taining information without a photographic image and solution of the prob- 1em of automation of the photointerpretation process (MacDonald, Kristof, 1970). In the tTnited States, on the basis of an analysis of data from a multispec- tral scanner obtained during the survey period April-July 1969 it was pos- sible to obtain interpretation criteria (sign-k,tures) of soils and agricul- tural crops corn, sorghum, cotton, ciLrus. It was established that their - identifiability is better during the early parts of the growing season (Wi.t;-.gand, et al., 1971). 182 FOR OFFICIAL USE ONLY -I APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY ~ Fig. 33.

If the moisture content is greater than this level, there is a linear dependence between the value of_ the reflected signal and soil moisture content. In the case of use of a microwave radiometer with a wavelength of 21 cm for a soil moisture content from 0 to 35% the reflection is a linear function of moisture content (Scfimugge, et al., 1974). In the USSR interesting investigations for measuring the moisture content of the earth's surface from space and using aerial vehicles are being carried out using SHF radiometric apparatus. In 1973 Basharinov, et al. (1974), in a survey from an aircraft using SHF apparatus, studied the radiation characteristics of soils for unirrigated lands in the middle (Kurskaya Oblast) and southern (Krymskaya Oblast) zones of the European USSR. Soil moisture content and the ir,fluence of vegetation on the radiobright- ness characteristics of moist soils were studied using radiameters having _ a res.ponse of about 0.5� and operating in the ranges 0.8 cm and 3.4 cm. The axes of antennas with angular resolutions 1 and 3� were oriented at angles 20 and 60� to the horizon. Resolution on the ground was from 1 m to 10 m because the fligfits were made at fieights from 50 m to hundreds of meters over the surface of the experimental sectors. - 252 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 Figure 49, for the territory of Krymskaya Oblast, shows the results of measurements ?nade after a rain. They show the infltience of the vegetation cover on the radiation characteristics of the moistened surface. The dif- _ ferences are most clearly visiTile wiien using a radiometer operating in the range 3.4 cm. In our investigations in the territory of the experimen;:al sector of the steppe zone during the field period we made determinations of soil mois- ture content fiy the thermoweight method along the aircraft flight path in fields with. different moisture content. Differences in surface moisture content of the fields in the layers 0-5 and 0-10 cm were as follows (megs- urements made 8 or 9 times): fields in sugarbeets 23.2 and 23.8%; fields in falloGr, dessicated from the surface 10.3 and 15.3%; fields in fallow after passage of a drill 19.3 and 21.5%. A comparison of theae data witfi_traces oTitaineci as a result of not less than 5 aircraft flights over the mentioned fields indicated that all these results of field moisture content were registered in cfianges of the instrument curve. Everything stated above makes it possible to consider this method to be promising for study of the soil cover, especially for determining the sur- face moistura content of soils. Radar Survey of the Soil Cover _ The use of radar systems is among the new photoelectronic methods for ob- taining information on soils and agricultural fields. The beginning of use of side-view radar systems, giving an image, dates back to 1950. This meth- - od substantial.ly supplements other systems giving an image of the soil cover. - IJsing a high-resolution radar, specialists in the United States carried out a survey of the Amazon and Orinoco basin, a territory in the moist equatiorial zone usually shrouded by cloud cover. The survey was made at a - scale of 1:400,000 with.a resolution of about 20 m on the ground. In 1970 the RADAM project was carried out for investigating soils, vegetation, re-- lief and mineral resources by means of a radar sutvey. Radar photographs are being used successfully for study of the moisture content of soils and river systems and in agriculture. They are being employed in inveatig- ating the distritiution of natural vegetation and sown crops, in predicting _ yields and in planning agronomic measures (Simonett, 1968). In the next 10 years radar surveys of the environment should become one of the prin- cipal methods for studying dynamic phenomena and processes. . The most valuable property of this new type of survey of the soil cover is that a radar apparatus can operate in the absence of visibility through ' fog and clouds and also at nighttime (Komarov, et al., 1973). This is es- peci111y import�ant in the study of the soil cover of the northern inac- cess_'ble regions of our country. In comparison with materials from an aer- ial photographic survey, the scale of radar images is small: from 1:60,000 253 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 0 FOR OF'FICIAL USE ONLY to 1:400,000. It ts not determined by the aircraft flight altitude but by the parameters of tfiE equipment zsed. Yn a radar survey of the soil cover the sources; of radiation of oraves in the centimeter range and the detector are situated aTaoard the aircraft. TTie signal reflected from the earth's - aurface, in the limits of the azi-mutfial angle wl.thin which the irradia- = tion. occurs, is picked up Fiy an antenna and after tranaformation of the radar signals. in the transmitter-receiver is registered on a cathode-ray tutae in the form of one scanning line. The intensity of the reflected sig- ~ nal, determining t:ie brightness of the luminous spot, ie dependent on the surface roughness, nature of the relfef in the analyzed territory, the ph.ysical properties of the soil cover, soil moisture content and the em- ployed wavelengtfi. By means of a ptiotoregistry unit the line image on the cathode-ray tufie and the intensity of the raflected signal are photogrAph- ed on a film whose :.ate of movement is propartional to the speed of air- craft movement. As a result, signals reflected from the eartFi's surface show up on a photo- graphic film with different intensity. The radar photoimage of the ground surface is similar to the aerial photcgraphic image and in its interpreta- tion it is possible to apply the experience of interpretation of aerial photographs. Tiie radar images give the detailed structure of local relief, _ a change of which. is closely linked to formation of the soil cover, its structure and complexity. Using radar images it is easy to interpret soils , which are moistened to different degrees; data from a radar survey can be used in identifying crops. An analysis of radar photograpfis at a scale of 1:90,000, obtained using the "Toros" side-view radar system (survey territory northern Balkhash regi.on (Severnoye Pribalkhash'ye), indicated that at the tops of ridges - and spurs a light gray tone corresponds to thin, poorly develnped gravelly brown desert-steppe soils formed on the eluvium of granites and quartz- porphyrites. A gray tone corresponds to brown desert-steppe poorly devel- oped soils formed on the fine-grained eluvium of sandstoaes. On proluvial deposits, from the dark gray image tone and the dendritic form of the soil contoura there is re7.iabla interpretation of ineadow-brown and meadow- chestnut soils. Frequently they are solonchak-like. The photoimage of al- luvial-meadow soils of the low terraces of major valleys is characterized by a banded pattern of gray and light gray eone in dependence an the de- gree of expression of the meadow process. A light s_'.7uous narrow band is the image of an intermittent watercourse. Using radar photographs of the territory of the semideserts of the northern Balkhash area it is possible to make a reliable interpretation of differi- _ ent types of Quaternary depasits, separate soils on the basis of moisten- ing regime into automorphous, polqhydromorphous and hydromorphous, and al- so use tfiese materials for soils regionalization (Semenova, Mozhayeva, k473). 254 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 In our investigations we used radar photograYhs of the territory of an experimental sector of the dry steppe zone at a small scale taken from an altitude af 4,500 m using the "Toros" system. The survey was made at nighttime in late Jul.y 1975 in the presence of stratocunulus clouds. An analysis of the radar ghotographs indicated that they can be used in re- liable interpreta.tion of tfie soil-geomorphological characteristics of the principal natural regions of this territory. For example, tfie photoimage of an undulating sandy plain is characterized by the presence of a great many lakes of a dark gray, almost black tone with a rim of solonchaks of an almost white tone. The image of dark chest- nut sandy and sandy loam soils has a moir4 pattern. Virginland vegetation shows up in a dark gray tone. An antierosional contour farming.system oc- = curs here widely. In the fields strips of an almost black tone cArrespond to stands of grasses (for the most part crestea wneargrass); strips with a light gray cone correspond to plantings of cQrn or sunflower. The image of the contour farming system is interpreted more clearly and with greater contrast from radar photographa than from materials from a multizanal - survey. The r.ext soil-geographic.region, occupying the territory of an ancient run- off trough with a complex soil cover, shows up on the radar photographs with a lesser contrast than on multizonal materials. Plantings of crested wheatgrass and virginland sectors show up in a dark gray tone on which sectors with solonetz soils show up as spots of a light gray tone. On these photographs of plateaus with dark chestnut calcareous and meadow- chestnut soils in swales it is easy to see squares of fields (with an area of 400 hectares) of a light gray tone the image of spring wheat. Against this background small spots of an almost black tone correspond well to meadow-chestnut soils; a light image tone corresponds to sectors of exca- vated dark chestnut soils. Amidst the squares of fields of a light gray tone, from the dark gray', al- most black image tone it is easy to interpret infrequent fields of bare fallow. Fields with plantiAgs of corn and sunflowers are reliably differ- _ entiated from the fields of spring wheat on these photographs due to their 6right-light image tone. Sectors with different sowing times were deter- mined amidst plantings of agricultural crops due to the different image tone. The eroded slope of plateaus toward the Turgaysl:aya depression was deter- mined ve:-y clearly on radar photographs from the nonuniform spotty-dendritic pattern of a light gray (blurred sectors), gray or dark gray tone. - The effectiveness of a radar survey of the soil cover is increased sharply when it is carried out during a period when the vegetation is without lea-,,~_-::,. The proper choice of the angle of inclination of the radar and its frequencies are also of great importance. 255 j FOR OFFICIAL USE OidLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 ~ ~ - - FOR OFFICIAL USE ONLY In order to study the composition of soils by means of side-view radare the surface is irradiated with radio waves of a definite length. By in- creasing the wavelength or the radiated power it is possible to determine the nature of the upper soil horizons.

Today the progress of soil mapping, the process of study of the soil cover, correction and compilation of soil maps is inconceivable without the use of aerospace materials. A soil map is the principal scientific document characterizing the productive-economic qualities of the land and therefore it plays an important role in its rational use. In the study of the soil _ cover and in the compilation of soil maps, carried out in our country by - a system of land use agencies and scient3fic research ins titutes,there must be an objective characterization of the natural characteristics of ~ the territory to be mapped, a high accuracy and detail in the represen.ta- tion of the soil cover and its scientifically sound generalization. The use of aerospace methods is exerting a revolutionizing j.nfluence in the aolu- tion of these problems. The refinement and acceleration of work in the compilation of soil maps are dependent to a considerable degree on the nature of the base used. It is entirely obvious that the higher the quality of the base used, the - greater will be the detail of the natural conditions represented on it and the better will be the quality of the soil survey results. A geographic base rich in detail makes it possible for the soil scientist, relatively simply and rapidly, to determine the position and rather precisely to - stipulate the sites for soil profiles and samples. A geographic base with a good representation of relief makea possible a considerably more pre- cise siting of soil profiles in its individual elements and far more re- liably define and draw the boundaries of soil units becaus e the spatial changes of soils are dependent to a considerable degree on relief changes. Investigations of recent years have shown (METODIKA SOSTAVLENIYA..., 1962; RUK017ODSTVO PO SOSTAVLENIYU POCHVENNYKH KART, 1964; KRUPNOMASSHTABNAYA KAR- TOGIta2IYA POCHSI, 1471) that the beat bases for the compilation and correc- tion of large-scale soil maps are topographic maps or aerial photoplans 257 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY with contours and aerial photographs. The earlier extensively used land use plans without the representation of relief are unsuitable for this purpose because soil maps compiled on such a base with respect to accuracy and qual- ity do not meet modern requirements. In addition, the work input of the soil scientist is very great when using thie type of base. The fundamental theoretical principles in the field of interpretation and - analysis of soil interpretation criteria were used in developing methods for the compilation of soil maps from aerial and apace photographa. Methods for the compilation of soil maps from aerial and space photographs (for territories in which soils have been poorly studied). The compilation o� soil maps by aerospace methods is subdivided into three stagea: prelim- inary offi.ce work, field work and final office work. When using aerial and space photographs, especially multizonal photographs, in this traditional process of investigating and mapping of the soil cover there is a marked _ increase in the volume of work on preliminary office procedures. In the first stage of the work a study is made of the literature and cartographic materials, including topographic maps of the investigated region. A topo- graphic map, in accordance with the scale used, makes it possible to obtai.n data on the characteristics of relief in the territory to be analyzedo How- - ever, it does noti make it possible to 3 udge the nature of the soil cover - over the territory of a farm, region or definite natural region to be mapp- _ ed and affords no possibility, still under office conditions, for defining the llmits and content of individual soil areas or units. In addition, for soil mapping the image of relief on topographic maps does not always fully reflect the microrelief in the territory. An aerospace survey makes possible the relatively rapid collection of materials with a high accuracy and ob- jectivity. In comparison with topographic maps they are characterized by a greater detail of the image of the earth's surfaee and wealth of detail, a direct or indirect representation of the soii cover and the possibility of establishing its interrelationahips with other landscape elements. At the same time, when working with space photographs there is a sharp in- crease in the role of topographic and soil maps available for the investi- gated region. This is attributable to threP factors: First, whereas when using aerial photographs orientation and tie-in are readily accomplished in the field, when using space photographs this work is done initially from maps and it must be remembered that the detail of the space photographs is greater than the detail of the maps (of sitnilar scales). Second, the use of soil and topographic maps makes it possible to clarify the possibilities of interpretation af soils on space photographs, the de- gree of detail and generalization of the image of soils, relief, hydro- graphic elements, and also to es.tablish interpretation criteria for a num- ber of soils. 258 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-00850R040340050024-7 ~ - Third, a topographic map (as in the case of aerial photographa) is used in convey ing the results of interpretation of space photographs (frequently unrectified) and in compiling a soil map of the corresponding scale. In Che preliminary period work on the use of serospace photographs for study of the soil cover begins with a general review from them, using a prelimin- ary montage of photomosaics of the investigated territory. It is necessary _ that these he constantly compared with materials on available soil maps and topographic maps. In the course of this work from the photoimage of the photographs and the nature of the relief on the topographic maps it is pos- _ sible to determine sectors with more or less uniform natural conditions - and to accomplish orientation and tie-in of aerial and space photographs to elements of the geographic situation on the topographic maps. This can be _ - done most reliably on the basis of an analysis of the hydrographic and - gully-ravine network (especially in the case of use of space photographs). In the case of large- and medium-scale surveys,from land use maps the admin- istrative boundaries of farms or regions are transferred to topographic maps and photographs during tne preliminary period and the photographs required for further work within their boundaries are kept. When using aerial photo- graphs having a 60% end lap within the limits of each flight line they are divided into two sets (even and odd numbers). One of the sets is used in defining the woric area; the other set of photographs is necessary �or a _ stereoscopic interpretation of the soil cover. : The next important stage is carrying out a prelitninary soil interpretation - on the basis of aerial and space photographs. When using aerial photographs for the compilation of large-scala (1:10,000-1:25,000) and medium-scale (1:100,000-1:200,000) soil maps this stage involves the following. - - By means of stereoscopic instruments (stereoscope, interpretoscope, etc.) and an analysis of interpretation criteria on photographs, within the lim- - its of the work area it is possible to define the boundaries of soil areas. The basis for their interpretation includes tone and'pattern (texture) of the photoimage, including the siae, shape and shadows of features, the na- ture of relief and other criteria. A summary of the soil areas is placed at the boundaries of the work areas. All the soil areas on the basis of the degree of interpretability dre classified as reliable, doubtful (shown by a dashed line) and those which cannot be determined under office conditions. In the stereoscopic interpretation of space photographs taken from altitudes of 200 km or more it must be remembered that only large forms of relief with an amplitude of 100 m or more are perceived three-dimensionally. In the office interpretation of doubtful soil units and those which cannot b e determined visually the soil scientist is assiated considerably by the use of an image analyzer the "Kvantimet=720." T?ie'experiments zahich have beE.: carried out have indicated that when it is used there is additional differentiation of uniform scil areas and an objective quantitative evalua- tion is obtained: _ 259 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY When the soil scientisc has a knoraledge of the soil cover of similar ter- ritories, when he has samples of the interpretation of soils from photo- graphs, it is possible to make a preliminary diagnostic determination of the soil cover which is then nartially checked in the field. If there are no interpretation samples for similar sails, the soil cover is unfamil.iar to the soil scientist or he has no experience in the interpretation of soils, the diagnostic interpretation of the soil cover is carried out only under field conditions. - In this connection it is possible to distinguish three principal variants: a) use of aerial and space photographs for refining existing soil maps for territories where the soils have been well studied (see next section) ; b) use of aerospace methods for refining and recompiling soil maps for terri- tories where the soils are poorly studied; c) use of aerospace methods in = soil mappir,g of inaccessible teri'itories where the soils have not b een stud- - ied. It was established when using multizonal photographs during the prelimin- - - ary office period that the principal results in soil interpretation should ' be obtained from photographs in the blue-green, red and IR zones, contain- ing the most soil information. Photographs in the IR and blue-green spec- tral zones under office conditions, together with photographs in the red zone, makE possible a mare reliable and obj ective interpretation of soils - and the obtaining of new information for a number of soil units. - After carrying out s nreliminary office interpretation of the soil covel the r.esults of the areal and in part the diagnostic determination of soils are transferred by means of appropriate proj ection instruments (pho to rec- tifier, projector, Clara camera, etc.) onto a topographic base. The re- = sults of soil interpretation are transferred onto a photoplan (if it is used as a base) using the geographic sjtuation and the photoimage, sim- ilar to photographs. In this way a map of the preliminary interpretation of soils is compiled. On the basis of this map and available photographs it is possible to de- termine soil-geomorphological regions for whic.h (when making a medium- ` scale soil survey) it is possible to prepare interpretation "%ays" (area one or two aerial photographs), select the most rational routes and siltes for obtaining the principal soil profiies and draw up a plan for a field soil investigation. - = Field studies for soil mapping purposes with the use of aerial and space photographs begin with a general familiarization with the soils in the - = process of a reconnaissance of the investigated territory. During the ini- tial period it is especially important, simultaneously with orientation, _ tie-in and description of tb,e soil profiles, to clarify stable interpreta- _ tion criteria for the soil cover. In a large-scale soil survey it is customary to use the continuous survey- _ ing method; in medium- and small-scale mapping the xeconnaissance-" key" survey method is employed. When "keys" a.re available work on soil mapping - 260 FOR. OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 and field interpretation begins from these sectors. Their number is de- termined during the the preliminary office period and is depe.ndent on the peculiarities of structure of the soil cover. In the case of a medium- - scale survey of a:oil-geomorphological region a soil interpretation "key" is prepared. In the case of "key sectors" the soil units and typical struc- tures of the soil cover are supported by soil profiles. In the course of this work there is accumulation of experience on the field interpretation = of soils, which makes it possible to proceed to the next stage in the - work on the mapping of the soil cover by the reconnaissance method. The sites for the soil profiles are determined on the photographs on the ba- - siG o.� the photoimage tone and pattern. The re connais sance- "key" method is used when space phetographs are employ- ed. A knowledge of the interpretation criteria makes possible successful interpretation of the soil cover between reconnaissance lines, applying the principle of geographic analogues. In the case of a good interpreta- bility of soils, especially when using a multizonal survey, the number of _ soil units discriminated from photographs is usually greater than when using only topographic maps. Accordingly, with retention of the norms es- tablished for a definite scale for the digging of the main and secondary pits a number of soil units will not be supplied with sucYL test pits. When using photographs their conditionality will be backed up by a slmilar photo- image with sectors for which there are test pits, as a result of a survey in "key" areas and along reconnaissance lines and extrapolation of the re- - sults to territories between field lines for which no data are available. For territo ries with a complex soil cover the number of main test pits may even be somewhat greater than set by the present-day norms. However, the number of test pits needed for clarifying the boundaries of soil unitg is reduced by several times. As a result, the use of photographs enables the soil scientist, working in the f-eld, to carry out a higher-quality, funda- mental study of the soil cover. The result of field work is a field compil- ation of a soil map with a legend and soil interpret. atiori symbols. In the post-field office period the materials from the soil survey and the results of the soil interpretation are formalized in final form. After the analytical processing of soil samples the legend and soil map are finally backed up with the writing of an axplanatory text to the map. The results of soil interpretation are finalized in the form of interpretation samples for the soil cover. These are usually prepared for the sector of "key inves- tigations." Each of the soil interpretation s:3mples consists of the principal photograph and two adjacent photographs (triplet) for a stereos.copic study of the soil cover. A sample of photo interpretation in the form of a fragment of the soil m ap with its legend is appended to them. The i,axt document is the explanatory text with a brief description of the = natural conditions, soil cover and characteristics of its interpretation with a compilation of a table of soil interpretation indicators. 261 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 - FOR OFFICIAL USE ONLY Interpretation samples, for the purpose of tlieir suUsequent use, are ac- companied by an indication of the taxonomic unit, in accordance with the scheme for soil-geographic regionalization of the USSR, the time when the survey is made, the scale and the type of film. In the case of multizonal photographs there is an indication of the spectral zone used and photo- graphs of other survey spectral zones are given. Methodological procedures for the compilation of inedium- and sma1T-scale soil maps from space photographs (for agriculturally exploited lands). At the present time in the agriculturally exploited territories of our country more than 94% of the kolkhoz and sovkhoz lands are supplied with large-scale soil maps. Accordingly, it is necessary to generalize this rich material " from soil mapping investigations of farms and compile medium- and small- scale soil maps for rayons, oblasts and individual republics in the country On the basis of investigations made during recent years in the field of _ medium- and small-scale soil mapping with the use of space photographs and with the compilation of samples of soil maps for different natural regions - of the steppe, dry steppe and desert zones, we will cite a number of ineth- odological instructions on the use of space photographs. _ 1. Depending on the complexity of the soil cover and the area of land cover- age, it is desirable that the generalization of data from a large-scale soil survey be carried out to scales 1:100,000, 1:300,000-1:500,000 and ~ 1:1,000,000. In the compilation of maps at a scale 1:100,000-1:200,000 it is possible to recommend aerial photographs at a scale of 1:30,000-1:100,000 and space photographs at a scale of 1:200,000, as well as original and enlarged photo- graphs at a scale of 1:1,000,000. In the compilation of maps at a scale of 1:300,000-1:500,000 it is necessary to use space photographs at a scale of 1:200,000, black-and-white and color spectrozonal photographs at a scale of 1:1,000,000, enlarged by a factor of _ 2-4, and also black-and-white multizonal photographs taken with the MKF-6 camera, and color photographs synthesized from them, enlarged by a facto: of 4-5 in comparison with their initial (1:2,100,000) scale. In the compilation of maps at a scale of 1:1,000,000 it is recommended that use be made of black-and-white and color spectrozonal space photographs at a scale of 1:1,000,000, enl3rged by a factor of 2-3, and multizonal photo- graphs, taken with a MKF-6 camera with enlargement by a factor of 3-5, as well as photographs at a scale of 1:200,000-1:300,000 with subsequent re- duction. It is also possl.ble to use space photographs at a scale of I:2,500,000 taken from the "Salyut" orbital station and enlarged 2X-5X. These same space materials can be used in the compilation of sheets of a soil map at a scale of 1:2,500,000. 262 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 ~ Experience has shown that in the compilation of inedinm- and small-scale soil maps it is desirable to use photographs of this same scale or twice as large. - 2. Work on the compilation of generalized soil maps at medium and small - scales with the use of space information can be divided into three stages: _ preliminary office, field and final office work. 3. The use in the office period of a complex of stereos,:opic, optical-elec- tronic apparatus for an analysis of pliotoimages, optical-mechanical projec- tors, photorectifiers and synthesizers for the synthesis and transfer of the results from photographs to a map base. Topographic sheets with a lightened map load, photoplans or photomaps at a corresponding scale are used as a map base for the compilation of soil maps. 4. In the preliminary office period the work begins with the collection and systematizing of large- and medium-scale soil maps, sheets of the StaCe Soil Map, materials from aerial and space surveys, and collection and study of sources in the literature for the investigated region. 5. Due to the fact that in the agriculturally exploited territories of the country the materials of the State Soil rfap contain thorough data on the structure of the soil cover, in a generalization of large- and medium-scale soil maps with the use of space materials there is a marked increase in the role of preliminary office work on both areal and genetic interpretation of soils. In the case of territories well supplied with soil mapping materials, the _ central place in the method for work on the compilation of small- and med- iinn-scale soil maps with the use of space photographs is occupied by a scientifically sound generalization of the soil cover and the implementa- _ tion of a high-quality synthesis of available soil data. In this connection ful.l use should be made of one of the principal advantages of space methods, specifically the possibility of using them in an analysis of the soil cover in close relationship to other environmental components; due to the great field of view of the space photographs and the coverage of consideraUle areas when they are used there is a considerable increase in the role of physiographic synthesis of natural phenomena and features, including soils. 6. Idork on the compilation of inedium- and small-scale soil maps with the use of space photographs begins with their orientation and tie-in to topo- graphic sheets of a corresponding scale, sheets of the State Soil Map and available medium-scale soil maps; the orientation and tie-in of space photographs is accomplished reliably by making use of elements of the oro- hydrographic network. 7. The first stage in the compilation of inediuTn- and small-scale soil maps froi, space photographs is their use in carrying out areal interpretation of soils employing stereascopic and optical-electronic instruments. Apply- ing in;:erpretation criteria (tone, photoimage pattern, character of relief, - 263 _ FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONL-f -I ~ etc.) it is possible to discr3.minate the boundaries of soil units on space photographs. The experience available in our country shows that in the i steppe, dry steppe and desert zones on small- and medium-scale space photo- graphs it is easy to interpret amidst zonal types (chernozems, chestnut ~ soils, brown desert-steppe soils, gray soils) soils of the hydromorphous _ s.eries: meadow-chestnut, meadow-chernozem, etc.; sandy soils and sands (ridged, barchan, hilly); soils formed on different soil-forming rocks; ~ alluvial and ancient alluvial, meadow and meadow-swampy; present-day and ~ ancient irrigated soils; eroded soils; takyrs; coastal (marsh) solonchaks, saline and meadow soils; mou,ztain soils; on medium-scale photographs _i a complex soil cover with solonetz soils, etc. It is possible to differen- tiate typical chernozems with moderate humus from those rich in humus; typ- ; ical chernozems can be differentiated from ordinary and especially south- ; ern chernozemss southern chernozems and dark chestnut soils can be dis- tinguished from chestnut soils; chestnut soils can be differentiated from ' brown desert-stepne soils; a complex soil cover of the dry steppe zone and -j brown desert-steppe solonetz-iike soils can be differentiated from solon- chak-like soils, etc. Clayey and clayey loam, sandy loam soils and soil of sandy mechanical composition cannot be interpreted or are determined doubt- fully; southern chernozems and dark chestnut soils, species differences of ! soils, etc. fall in the same category. 8. When using materials from a multizonal space survey it is necessary to use color synthesized photographs or black-and-white photographs in the red _ zone with additional information obtained from photographs taken in the IR and blue-green spectral zones. In the case of soil units not clearly ex- pressed (visually) on the photographs considerable help can be obtained by the use of image analyzers of the "ISI," "Kvantimet-720," "Densitron" and other types which with the aid of corresponding densitometric units empha- size tonal differences in the color or black-and-white scale of soil cover - images. 9. The results of areal interpretation of soils by the optical or mechan- ical method are transferred from the photographs onto the sheets of topo- - graphic maps and are tied-in to relief elements and the results of inter- - pretation on adjacent photographs. Thereafter the soil areas on the space photographs obtained in optically generalized form for the corresponding _ survey scale are compared with the soil units on the State Soil Map. A ' diagnostic interpretation of the soil cover is made on the basis of this comparison. There can be two principal variantso The first is when the photo- image detail of the soil cover on space photographs (or some of them) is less than on the shee;s of the State Soil Map. In this case the soil map data are used for an interpretation of soils on the space photographs and their subsequent use for the compilation of general soil maps. The second case is when the accuracy in discrimxnating soil units and degree of de- tail of the soil cover photoimage and its structure on the space photo- graphs (or on some of them) are more detailed than on the sheets of the _ State Soil Map. In this case, on the one hand, there is a refinement of the content and detail of this map (on the basis of space interpretation data), 264 FOR OFFICIAL USE ONLX APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 and on the other hand, for a diagnostic identification of the soil units discriminat -ad from space photographs use is made of data from a medium- scale mapp ing of soils. In such cases it is possible to use the results of generali zation of data from large-scale surveys carried out earlier or made direct 1y in the course of compilation of small- or medium-scale soil maps from space photographs. 10. The stage of generalization of materials from large-scale soil maps (to medium scales 1:50,000-1:100,000 and 1:200,000),to the level of re- gional soil maps,must be carried out with the use of aerial photographic surveys at a scale of 1:25,000-1:30,000. In this stage there is refinement and correct ion of soil units on the basis of aerial photographs and an in- itial objec tive generalization of the soil cover with a reflection of the nature of the soil textures shown on the photographs. The generalization, iihich begins with a generalization of the map legends, is carried out on the princip 1e of the similarity of soils in genesis and productive sig- nificance. It is expressed in a combining of small soil units into larger - units, the compilation (taking the soil aerial photographic image into _ account) of new generalized units, including soil combinations, complexes and mosaics . The minimum unit for soils having clear boundaries and dif- ferent gene sis is 25 mmZ, for units having sharp boundaries and similar _ genesis 50 mm2> for soils with gradua.l transition boundaries 100 mm2. When discrirninating complex units from aerial photogra.phs there is refine- = rtient of the 3r percentage content of secondary and tertiary components, taking taking into account the general subdivisi:ons for their discrimina- tion: up to 10%, from 10 to 25%, from 25 to SO%o 11. The pro cess of generalization and conversion from the content of soil - maps of a larger scale to a mediinn or smaller scale with the correspond- , ing use of aerial and space photographs should be as 1:2 or 1:3, that is, from a scal e of 1:25,000-1:50,000 to 1:100,000-1:200,000, then to 1:300,000 or 1:500,00 O and finally to m3ps at a scale of 1:1,000,000. This will make possible the most complete and precise retention of the characteristics of structure o f the soil cover,in individual natural regions appearing on pho- tographs and reflection of the geographical similaritq of the soil cover in the investigated territory. In the comp 3lation of small-scale soil maps from space photographs individ- ual large- s cale soil maps of farms and medium-scale maps of regions sel- ected for characteristic natural-geomorphological regions can serve as inserted " keys" necessary for the compilation of more complete and inform- - ative maps, taking into account the structure of the soil cover. 12. On the basis of areal and genetic interpretation of space photographs, employing materials from earlier soil investigations and sheets of the State Soil Map,during the preliminary office period there is compilation of iiedium- or small-scale soil maps and the places and routes for partial checking of the content of these maps in the field are selected. 265 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY 13. During the field period for soil mapping, with the use of space photo- _ graphs, there is a general familiarization with natural conditions, soils - and their field interpretation along the reconnaissance route. Doubtful sectors of the soil map are checked and refined, a series of primary soil ' profiles is prepared and materials are collected for the compilation of additional maps and cartograms. Stable interpreCation criteria are estab- lished fnr the soil cover. Soil samples.are collected for carrying out genetic analyses and studying the reflectivity of soils. As a result, the final compilation of the soil map with an appropriate legend is finalized in the field. 14. In the office post-field period the soil map is put into its final form and an explanatory note for the map is prepared. The results of the office and field interpretation of soils are formalized in the form of soil in- _ terpretation keys, based on space photographs, composite tables and indi- cators of soil interpretation criteria and an explanatory text devoted to - the peculiarities of their interpretation applicable to definite natural and technical survey conditions. Effectiveness of Compilation of Soil Maps from Aerial Photographs The matter of the effectiveness of use of materials from an aerial photo- graphic survey for soil mapping will be examined in the example of compil- ation of a large-scale soil map of the "Krasnyy Oktyabr kolkhoz in Kur- manayevskiy Rayon of Orenburgskaya Oblast and medium-scale maps of three - farms in the territory of the Mongolian People's Repub,lic. The soil cover of the investigated sector of the territory of Orenburgsk- aya Oblast was represented by southern (ordinary, terraced, with reduced effervescence, solonetz-like) chernozems, of different mechanical composi- tion, formed on different soil-forming rocks, meadow-chernozem soils, . steppe and meadow-steppe solonetz soils.:and alluvial soils. The use of materials from an aerial photographic survey was effective for this terri- tory, complex in its soil geography (it is in the third category of dif- ficulty). In the course of the work this assumption was completely con- firmed. In order to characterize the soil cover (area 11,900 hectares, _ survey scale 1:25,000) a total of 336 test pits were dug, of which 235 were primary (depth 150-200 cm). This number, 1 test pit each 50 hectares, corresponds to the norms for the number of test pits per unit area in de- pendence on survey scale and the terrain categoYy appropriate for soil _ cover complexity. llowever, not all the soil units were characterized by test pits. A number of soil units having a similar photoimage on the aerial photographs (pat- tern, tone) and situated under uniform relief conditions were characteriz- ed on the basis of extrapolation of data. The sites for the digging of test holes (primary and secondary) in the terrain and the density of the reconnaissance lines were determined by the peculiarities of the soil 266 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 photoimage on the photographs and photoplan with contours, which was used as an up-to-date base. The use of aerial methods indicated that under the conditions of this nat- ural region, southern chernozems, southern terraced chernozems of inedium - and small thickness, meadow-chernozem and alluvial soils are interpreted with great effectiveness. On w.ter divides there is reliable discrimina- - tion of homogeneous and complex snil units with the participation of sol- : onetz soils. Southern chernozems formed on different rocks, thin gravelly chernozems and steppe solonetz soils were doubtfully discriminated. On the photoimage it was impossible to discriminate southern clayey, heavy clayey loam and clayey loam chernozems and meadow-chernozem soils of different degrees of leaching, etc., that is, soils of close taxonomic ranks, the characteristics of which are not manifested significantly in the optical properties of soils, were not discriminated on the photoimage. The use of aerial photographs made it possible to detect a number of reli- - able interpretation criteria for the mapping, on their taasis, of such - peculiarities of the soil cover important for production as discrimination of areas subject to deflation, areas of different degrees of water ero- sion, areas with complexes with different quantities of solonetz on old cultivated lands and areas with different types of intraunit soil nonuni- formity. Thus, for the territory of the dry steppe zone there was found to be a considerable effectiveness of use of aerial methods in the large-scale mapping of soils. It is expressed in a reduction of, the number of test holes by a factor of 2-3 with retention of the necessary accuracy in the discrimination of soil units, a deeper study of the soil cover and its structure by means of primary and secondary test holes, the number of which is not lcwer, but even higher than the necessary norms; on the soil map there is objective expression of characteristics of the soil cover which are of importance for production. The use of aerial methods made it pos- sible with a high accuracy (in sectors where the soils were interpreted reliably the units were discriminated with topographic accuracy) and com- pleteness to map the soil cover and compile a soil map objectively re- flecting the soil resources of the investigated region. - The use of aerial methods is still more effective in the compilation of medium-scale soil maps. We will examine the use of aerial photographs in the soil mapping of three farms in the Mongolian People's Republic, which was carried out during 1971-1974 jointly by L. P. Rubtsova and G. A. Shershukova under the direction of N. A. Nogina. When this work was done . use was made of the reconnaissance-"key" survey method with the compila- tion of a preliminary soil interpretation map on the basis of aerial photographs during the office period for the entire territory of the farm. ThP number of test pits and "key sectors," as well as the density of the fieid reconnaissance lines,was different in dependence on the complexity of the soil cover in the investigated region and its interpretability on aerial photographs. 267 ' FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY In a soil survey at a scale of 1:100,000 of the "Tuvshrulekh" farm, locat- ed in the wooded steppe zone, topographic maps at a scale of 1:100,000 and aPrial photographs at a scale of 1:60,000 were tised as bases. A com- parative analysis of these materials indicated that under mountainous conditions the relief image on the aerial photographs is highly distorted , and it is difficult to interpret ttee soil cover through forest vegetation. On the other hand, topographic maps in great detail convey the nature of the relief (steepness, exposure, length of slopes) of a mountainous zerri- tory. In a steppe loc,rland part of the farm the use of the tone and pattern of the photoimage on the aerial photographs made possible a reliabZe dis- crimination of ineadow-chestnut and meadow solonchak-like soils associated with flat intermontane basins which on the topographic maps had a uniform pattern of the contour lines. On the other hand, smoothed ridges with . ch.estnut soils, clearZy noted on the topographic map, were sometimes poor- ly traced on aerial photographs. - In order to characterize the soil cover 358 test pits were dug in the four man-months of the survey. Computations indicated that for the third cate- gory of difficulty, to which the investigated territory of the farm was " assigned (nozm 32,000 hectares per month), the soil map was compiled within the limits of the existing work norms for this survey scale (1 test hole per 400 hectares). The somewhat grpater number of test holes dug in this territory in compar- ison with the adopted norms explains the increased accuracy of tlae map and iics more complete content as a result of use of aerial methods. With re- spect to the accuracy and volume of soil information (due to the use of data from aerial photographs at a scale of 1:60,000) the soil map for the _ "Tuvshrulekh" farm approaches a scale of 1:50,000. As a result, it can be assumed that the final compilation of the soil map at a scale of 1:100,000 is twice as complete and is of a higher quality in content due to the use of aerial methods. At the "Unzhul" farm, typical for the steppe zone of the Mongolian People's Republic, a scientific-production soil survey at a scale of 1:200,000 was carried out over an area of 319,000 hectares using topographic maps at a scale of 1:100,000 with the use of aerial photographs at a scale of 1:32,000. In natural respects the analyzed territory can be assigned to the dry steppe with the widespread occurrence of chestnut soils. The re- connaissance-key research method was employed when carrying out soil map - work. In the preliminary office period over the entire survey area a pre- - liminary soil interpretation map was compiled (with the use of a stereo- scope and aerial photographs). The results of the interpretation were transferred to a topographic base at a scale of 1:100,000. An analysis of the photoimage of this territory made it possible to divide it into three major soil-geomorphological regions and the valley of the Tola River, for which four "key" sectors were selected, each of which characterizes a typical dry steppe landscape. nuring the field period 268 - FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 work on the mapping of the territory (after a general reconnaissance) was begun from these sectors (each with an area 30-60 lmn2) for the purpose of detecting from photographs at a scale 1:32,000 soil cover structures. Work in the key sectors was done using a denser network of test pits than else- where.In a reconnaissance survey (distance between lines 4-5 km) use was made of the principle of extrapolation of collected data. A total of 570 test holes were dug in the field period in compiling a field compilation of a soil map at 1:100,000, which in content had information from aerial phntographs at a scale of 1:32,000. In order to support a final _ map at a scale of 1:200,000, in accordance with the third category of dif- ficulty, to which the investigated territory was assigned, the number of test pits dug was somewhat greater than according to the adopted norms. This is related to the more complete map represenltation of the content of the soil cover and its structure when using aerial photographs. In general, aerial methods increased the qua.Iity of the investigations made and the soil map and the completeness of its content was doubled or tripled. Soil interpretation keys or samples were prepared during the final office period; the basis for these was the "key" sectors. It was established that the specific nature of soil interpretation in this territory is relat- ed, on the one hand, to the fact that this is a natural region with clear�- , ly expressed features of macro- and mesorelief, and on the other hand, that - this is a zone of steppe virginland vegetation, poorly affected by agri- cultural exploitation. Accordingly, the basis was an indirect interpreta- tion of the soil cover, accomplished through the direct image of relief and steppe vegetation. In the semidesert zone of the Mongolian People's Republic a soil survey at a scale of 1:200,000 was carried out in the territory of the "Bulgan" farm. As a base for compilation of the soil map use was made of sheets of a topographic map at a scale of 1:100,000 and aerial photographs at a scale of 1:32,000. The survey was made over a two-year period. During the first year a total of 360,000 hecCares was mapped of a total area of 830,000 hec- tares. The good surface exposure of the territory (the projective coverage of the soil surface by vegetation here is from 3-4 to 12-20%) made it pos- sible to have`a very clear contrasting image of the soil cover on the aer- ial photographs. _ The method f.or compiling the soil map was as follows. During the prelimin- ary office period aerial photographs were obtained on which after delin- esting the work areas by means of a mirror-lens stereoscope it was pos- sible to carry out visual-instrumental soil interpretation. On rhe basis of an analysis of the aerial photographic image for the first year of the _ soil survey it was possible to'define five "key" sectors taking in differ- ent geomorphological territories: a foothill area, a sloping proluvial- denudational plain with absolute elevations of 1,700-1,350 m(here three "key" sectors were selected) and an erosional-de.nudational plain of an av- erage level with absolute elevations of 1,300-1,100 m(two "key" sectors), 269 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 - FOR OFFICIAL USE ONLY = In the preliminary office period, using aerial photographs for the entire survey area, it was possible to compile a preliminary soil interpretation . map with the soils being transferred from aerial photographs to sheets of a topographic map at a scale of 1:100,000. During the field period work on compilation of the soil map began from the "key" sectors, each of which covered an area of 25 kmz. Work in these areas for study of the soil cover, its structure and the different charac- ter of the photoimage was carried out using photographs at a scale of 1:32,000 and a grid of test pits of increased density (up to 1-2 km). Thereafter, a reconnaissance soil survey was made with the distance be- tween reconnaissance lines being 4-5 km. The investigations indicated that for tfie territory of the foothill plain it was possible to extrapolate - successfully the interpretation criteria for brown desert-steppe and water- shed soils determined in "key" sectors to a distance of SO km or more. In - the territory of the erosional-denudational plain it was easy to determine different forms of sand (barchan,.ridged, hilly) from the photographs and extrapolate them for tens and hundreds of kilometers. It was easy to de- termine highly eroded sectors of the soil ro�,rer with surface outcrops of Tertiary reddish rocks and erosional deflation basins. According to the existing production norms, for a scale of 1:200,000 one - worker is assigned 120,000 hectares per mor.th. Therefore, the work area of 3605000 hectares called for 3.5 man-months. Taking into account that a field copy of the map was compiled at a scale of 1:100,000, the work productiv- ity was'twice as great. This.effect during the field period is attribut- able, on the one hand, to the fact that a soil map was compiled first, - and on the other hand, to the use of materials from an aerial photographic survey with good interpretability of the soil cover. A total of 376 test pits were dug for compilation of an interim soil map during field work. According to the existing norms (1 test pit per 1,200 hectares) for ter- - ritories of the second category of difficulty, to which the lands of the farm were assigned, it would be adequate to have 290-300 test pits. The somewhat greater number of soil test holes dug is attributable to the high information content of the aerial photographs with respect to the photoimage of the soil cover and its structure. The following year this soil survey work was continued; full use was made of the earlier experi- ence in office and field work in this territory. About 700 soil test pits were dug in an area of 830,000 hectares during two field seasons. The use of aerial photographs made it possible to create a precise soil map, complete in content. Somewhat generalized information from aerial photo- graphs at a scale of 1:32,000 was used in creating a field compilation of a soil map at a scale of 1:100,000. If it is taken into account that _ the final compilation of the soil map was at a scale of 1:200,000, the completeness of the content and the quality af the map, as a result of the use of aerial methods, increased not less than two- or threefold. The scientific-productive irivestigations which were made indicate a con- siderable effectiveness of use of aerial methods in soil science in the study and mapping of the soil cover.

According to data published by Yu. G. Kel'- ner and G. N. Romankevich, specialists at the "Priroda" State Scientific- Production Center of the Main Arlministration of Geo desy and Cartography _ of the USSR Council of Ministers, the saving of work expenditures in dif- ferent stages of compilation and revision of special maps from space pho- _ tographs is from 10 to 70% (Tablz 46). - These data show that the economic effectiveness of use of space photographs - in special, including soil, mapping, is quite high. It wi11 be still high- - er as the methods and instrumentation of a space survey continue to im- prave and as the mapping method is improved. The real annual economic effect from the use of space materials in the study of soils and special mapping in the UnitedStates and Canada even today is reckoned in the tens of millions of dollars (Table 47). - The use of space photographs in the study of soil resources in soil mapp- ing increases the effectiveness of work of the soil scientist with re- spect to the accuracy and completeness of the inves tigations. A small-scale soil map was compiled for the territory of southeastern Kaz- akhstan using multi2onal space photographs from the "Soyuz-22." Sheets from a medium-scale soil map of Kazakhstan were used in the interpretation and in the compilation of this map. Areas of sands are shown more precise- _ ly and completely on the map compiled from the photographs; areas of soils ' situated on the alluvial fans of mountain rivers and in the territories L adjacent to thEm were clearly defined cartographically with topographic accuracy'. On a photograph in the IR zone tIiere was more reliable plotting of an area of ineadow-swampy and alluvial meadow soils, etc. The soil map compiled as a result of interpretation of multizonal photo- ;raphs was compared with a smail-scale soil map (the map scales were sim- ilar) available for this territory. The anaZysis indicated that the inter- pretation of the soil cover from space photographs made it possible to _ compile not only a more precise, complete and detailed (48 soil subdiv- - isions and their complexes were discriminated instead of th.e 26 determin- ed, earlier), but also qualitatively new map, most completely reflecting the principal geographic patterns of structure of the so il cover in this territory of southeastern Kazakhstan (Fig. 50, 50a). = A similar soil mapping investigation was carried out in the territory of the lower course of the Indus River. A comparative analysis of t`.z soil map of this territory with the soil map obtained,as a result of interpret- ati_on of space photographs from the ERTS satellite indicated that the - initial map reqiiired refinements of the boundary of mountain cinnamon and mountain gray soils, gray soils of typical desertif ied ephemeral steppes, _ 275 ~ APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY }4a ~3 40 5 ~7 9 ~10 11 ~12 13 Fig. 51a.

Using space photographs with a topographic degree of accuracy it was possible to interpret an area of - floodplain alluvial soils along the valley of the Indus River, constitut- ing an important land resource of Pakistana On the photographs it is easy to see the internal nonuniformity of the photoimage of these soils the presence of sectors of secondary salinization. The soil cover in the des- ert shows up more differentially on the space photographs. Whereas on the soil map of the lower course of the Indus River it had earlier been pos- sible to discriminate nine soil subdivisions, after the interpretation 13 _ could be discriminated. As a result, tiie new soil map began to reflect the land resources of the analyzed territory more completely and objectively _ (Fig. 51, Sla). - Experience in study of the possibility of using small-scale sFace photo- graphs (scale 1:1,000,000-1:2,500,000) for refining existing soil maps (of similar scales) for different natural zones indicated that the inter- - pretability of the soil cover and the effecti.veness of map compilation for the territory of the dry steppe and desert zones is several times greater than fox the steppe zone. Space photographs, as a result of their greater coverage and image gener- alization, for the first time made it possible to interpret and carto- graphically more precisely discriminate ancient deltas and their soil cover on maps. - It was demonstrated on the basis of investigations with the use of multi- zonal space photographs that in small-scale soil mapping there can be a marked improvement in the principle of geographic similarity of the image of soils and their complexes on a map of soil cover structure in the ter- rain. In most cases the geographic base for the compilation of soil maps is topographic maps, on which there is no image of the soil cover. Ac- cordingly, in its generalizati.on without the use of space photograpYts ' the specific structure of the soil cover of individual natural regions and geographic zones is represented i:icompletely. One of the principal advan- _ tages of use of space photographs in the field of soil mapping is the ef- fect from a space classification of the soil cover. This theoretical prin- ciple is particularly important because soil mapping is a spec3al method for spatial investigation and representation of structure of the environ- ment. - In conclusion we will cite data on investigations of the effectiveness of space photographs for compilation of a small-scale soil map of the Caspian _ area (Table 48). Promising Directions in the Use of Aerospace Methods for Study of Soil and Agricultural Resources ln soil science and agriculture, taking into account the needs of our coun- try in the immec'iate future, it is necessary to develop the following fun- damental direc:.ions in the field of use of aerospace materials.

Aerospace materials can be used in solving the following problems: a) de- termination of the intensity of water and wind erosion; mapping of eroded soils from space photographs and ascertaining the effectiveness of pro- tective measures for the conservation of soils; determination of centers of propagation of sand and dust storms; b) detection of areas of soils disrupted by industrial development and monitoring of ineasures for their r.t:atoration; c) investigations of shore destruction of canals and reser- voirs, determining areas of inundativn of soils in the zone of their 279 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/48: CIA-RDP82-44850R000300054424-7 FOR OFFICIAL USE ONLY activity; d) determining the resources of swampy, eroded, saline lands, especially in inaccessible regions of the country; e) development and - improvement aF the method for the study of soils requiring melioration from space survey photographs; determination of areas of seasonally and periodically saline soils; monitoring of the functioning of irrigation and drainage systems using materials from repeated space surveys; inven- torying the state and change in the quality of soils and areas of cultiv- ated lar.3s under the influence of irrigation and drainage improvements; de- tecti.on of overdried lands; ascertaining the nature of moistening, times of the next irrigation and leaching.

A qualitatively new jump in the study of the soil-agricultural resources- of the earth has occurred during the last 5-10 years in connection with the use af space and multizonal aerospace research methods. Both photo- graphic and photoelectronic methods have been successfully developed. The investigations which have been carried out with the use of aerospace methods for the study of soils and generalization of the Soviet and for- - eign experience have made it possible to obtain the following results. ~ 1. It has been established that aerospace methods are of great importance for objective (reliable), precise and thorough routine collection and in- terpretation of information on land (soils-agricultural) resources. Space photographs, covering extensive territories of the earth, ma.ke it possible to see and map the latitudinal and vertical zonality of soils and also to compile and refine soil maps of inedium and small scales which are more complete in content. This effect is 1.5-2 times greater for the dry steppe and desert zones in comparison with the methods used earlier. On space photographs there is an objective optical generalization of the soil cover, and as a result the concept of simple and complex integration - has been introduced into space interpretation theory. The first is char- - acteristic for the reflection of combinations of soils on photographs, and the second for the photoimage of soil complexes. - Space methods constituta an important tool for monitoring the state of soils for the purpose of presexving and predicting the soil medium and soil fertility. On phot-.ographs there is reliable interpretation of irri- gated lands from the contrast in color of moist irrigated and dry unirri- gat?d soils. Due to the extensive coverage of space photographs and the ge:ieralization of details on them there is a clear representation of sec- tors of the soil cover of modern deltas and it is possible to interpret 282 FOR OFFICTAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 soils of ancient river deltas of different age which earlier could not be clearly detected car to graphically by other methods. Space photographs are used in agricultural interpretation for ascertaining the processing of soils and for determining the type of agricultural crops. We have introduced the concept of the effect of space classification of the soil cover into the theory of soil interpretation. 2. An examination of the theoretical principles of interpretation of the soil cover from aerospace materials indicated that at the present time the basic method is the visual-instrumental method for investigating soils in which there is the most complete use of the logical inferences of the in- terpreter and a quantitative analysis of the photoimage of the photographs is employed. - A quantitative visual-instrumental method has been proposed for the inter- pretation of soils and agricultural crops (with use of a"Kvantimet-720" image analyzer) using aerospace photographs. The interpretability of fea- tures is evaluated in relative units from the difference in the level of the gray tone of adjacent soil and vegetation units. A quantitative scaJ.e for evaluating the degree of interpretability of objects has been proposed within the limits of the instrument operating range (64 levels of gray _ tone). Using this instrument, on the photographs amidst visually seemingly homogeneous almost white, gray or almost black images of soils or crop areas, it is possible to detect tone differentiation, which is of great importance in the mapping of soils. A machine analysis of photographs made using the "Kvantimet-720" made possible a differentiated, precise and ob-,, jective compilation of soil maps. The objectives of soil interpretation are, first of all, the detection of genetic varieties of soil cover on aerial and space photographs and their outlining, and second, determination and analysis of the soil units detect- ed on the photographs. An important and independent task is the extrapola- tion of the soil results to similar territories. An analysis of the complex of interpretable criteria (direct tone, color, texture, shape, size of the soil units; indirect characteristics of relief, hydrography, vege- tation, man's agricultural activity) is the basis for the successful in- cerpretation of soils. . A classification of textures (parterns) of the photolmage of the soil cover - on aerial and space photographs, a necessary condition for reliable inter- pretation of soils, was developedo In connection with the automation of - interpretation a new direction is developing study of the language of the photoimage of photographs by the recognition of characteriatic struc- - tures. The basis for the class ification of textures of the soil cover image is the objective difference in the patterns registered on the photographs, in -?ependence on the genetic sotl varieties to which they correspond. This principle makes it possible, in an extrapolation process, to use the dis- criminated textures of the photoimage for a successful diagnostic interpret- ation of the soil cover of similar territories. 283 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY A study of the spectral reflectivity of soils in the steppe and dry steppe zones,,taking into account the total reflection coefficient and in a defin- ite narraw snpc:-ral zone,indicated that the lesser the humus content in the soil, the greater the content of carbonates, the lighter the nechanical composition, the greater is the reflectivity and the lighter ia the soil image on the photographa. The calcareous nature of the soils and rocks is _ manifested quite sharply in the blue-green spectral zone where the soils usually have lcw reflecticn coefficients. A joint analysis of the reflect- ivity of soils and multizonal photographs made it passible to diagnose the soils developed en different rocks. Color is a reliable interpretation criterion for soils. Photographs of the SN-6, SN-23 and SN-8 types were the l:zst of the color spectrozonal mater- _ ials for soil purposes. On the basis of the extent of -he soil units there is reliable discrimina- tion of sectors with a uniform soil cover and soil complexes; on the basis of extent and shape it is possible to ascertain different elements of gully erosian. The extent and shape of the soil contours are governed by the nature of the relief and serve as a component part of the different tex- tures of the photoimage of the soil cover. The largest relief elements (geotexture and morphoatructure of the earth's surface) are shown in optically generalized form on medium- and small-scale space photographs. Morphoscu!.ptural elements, which constitute the basis - for indirect interpretation o`'soils on the basis of aerial survey mater- _ ia1s, frequently cannot be seei: on space photographs. It was established in the interpretation of soils through culti sated vege- tation that dense full-grown plantings conceal the surface and the struc- ture of the soil surface. However, in a number of cases they can emphasize the differences in thc: degree of exosion, moisture content, solonetzifica- tion and fertility of soils. Grain crops from the sprouting phase to the phase of stem extension and young tilled crops exert virtually no influence on the soil photoimage. The soil cover of steppe areas is reliably inter- preted through meadow and steppe virgin land vegetation on the basis of tone and especially the pattern of its photoimage on photographs. 3. The specifir_ nature of use of interpretation criteria in the interpreta- tion of soil-agricultural features from space photographs involves the fol- lowing. In the interpretation of soils from space photographs, due to the great areal coverage of considerable territories, ther.e is a marked increase in the role of physiographic synthesis allowance for indirect criteria, interrelationships and intercausalities of'all environmental components. When using tone it must be remembered that on spa::e photographs it is com- mon to have to contend with the integral phototone of the soil cover image. B 284 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 On space photographs there is clear interpretation of a spotty form of soil areas with a contrasting soil cover (solonchaks, meadow-swamp soils of depressions), but 1 inear, meandering and dendritic forms are determined still more reliably. Whereas on aerial photographs there is representa- _ tion of individual forms of soil units, space photographs show entire re- gions of similar shapes and dimensions. On space photographs the image texture of the soil cover is also specific; it is caused by the generalization of individua.l details of structure of _ the earth's surface; it was established that the very same geometrical form of texture (pattern) on aerial and space photographs can have a dif- - ferent content. 4. It has been established that new possibilities for a mpre complete and objective interpretation of soils and areas of agricultural crops are be- ing affordad by the use of mul.tizonal aerial and space ghotographso Investigations have shown that when using multizonal aerial photographs the highest quality of interpretation (accuracy, completeness, reliabil- ity) of the soil cover and agricultural crops u*as obtained with the joint - use of photographs taken in the green, red and IR spectral zones. In the steppe zone, using multizonal aerial photographs taken in the IR region in the autumn period of a survey, it is possible to detect the greatest difference between fields of winter wheat scwn in clean and oc- cupied fallow. This makes it possible to predict its crop yield for the - future year. Using autumn aerial photographs taken in the red zone there is reliable determination of typical chernozems, eroded chernozems and - meadow- cherno zem so ils in plowed fields, as well as plantings of perennial grasses and sectors of unmown steppe amidst areas of mown steppe. Meadow- chernozem soils associated with microdepressions were interpreted through the photoimage of cultivated crops (sugar beets) on the basis of the spotty-d~tted pattern on autumn photographs taken in the green zone. These could not be seen through cultivated plantings on autumn photographs tak- en in the red and IR spectral zones. On aerial photographs of surveys made in the early siunm:Ftr (June) chernozem soils were visible in all three spec- tral zoites through the image of cultivated crops. They were not interpret- ed through plantings of grain crops. In the dry steppe zone, using multizonal aerial photographs taken in the red zone, there was successful interpretation of the soil cover (dark chestnut,'meadow-ch estnut, solonetz) through the direct image of grain and cultIvated crops. In the green and IR spectral zones it shows up less clearly or cannot b e interpreted at all. Using summer and autumn photo- graphs takzn in the green and especially in the red and IR zones it was possible to determine fields of spring wheat and barley diffexing in crop yield by a factor of 1.5-2. Using July pbotographs of the IR spectral zone there is reliable interpretation of the Field of grain crops in dependence on the nature of the preceding working of the soils (fallow, deep loosening - 285 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY and leveling). In this spectral zone there was also reliable determina- tion of fields with different times of sowing of grain and cultivated crops and fields of bare fallowo In the desert zone, in irrigated lands, using multispectral aerial pho to- graphs, it was possible to make reliable interpretations of gray soils and gray-brown gypsum-bearing soils of adyry (low foothills surrounding a de- pression), old irrigated, meadow gray soils and newly zrrigated highly saline soils with the participation of solonchaks and gray sands. Amidst the sandy complexes in the blue-green zone there is reliable interpreta- tion of barchan deflated sands, small mounds of sands, depressions between ridges with ground water at a shallow depth and masses of consolidated gray sands. Among the agricultural crops plantings of cotton and grasses (alfalfa, Sudan grass) are readily distinguished. 5. During recent years a multizonal space survey has been coming into in- creasingly broader use in study o.f the soil cover. _ On one of the multizonal space photographs for the first time obtained in - our country fr.om the "Soyuz-12, for the territory of the Mangyshlak P lat- eau it was possible to have reliable interpretation of gray-brown solonetz- like (gray and light gray tones) and gray-brown solonchak-like (dark gray tone) soils, as well as chestnut soils in the Raratau Range. They were poorly interpreted or not interpreted at all in the blue zone of the spectrum and had the sharpest image contrast in the yellow-orange-red (0.58-0.64p.m) spectral zone. Solonchaks and sands were determined with - the joint use of photographs in the blue and yellow-orange-red spectral zones. The use of space photographs from the "Salyut-4" for the interpre_aticn of soils in a mountainous territory indicated that the best result was ob- tained using color synthesized photographs and b lack-and-white photographs taken in the zone 0.5-0.6 and 0.6-0.7m. An interpretation or the soil cover of the steppe and desert zones using multizonal space photographs taken from the ERTS (United States) indicated that photographs in the range 0.6-0.7� m have the sharpest contrast of the photoimage of soils and agricultural crops. On photographs in the zone 0.8- 1.1um it is easy to interpret the channels of r ivers along which alluvial soils are reliably determined. Irrigated fields are reliably determined amidst arid lands on photographs in this IR spectral range. In general, for successful soils-agricultural interpretation from multizonal photo- ~ graphs of the ERTS-Landsat it is necessary to make joint use of photographs in the spectral zones 0.5-0.6, 0.6-0.7 and 0.8-1.1 pm. An analysis of multizonal space photographs taken from the "Soyuz-22" indi- cated that the most precise vljual-instrumental discrimination of soil units and a thorough image of the soil cover was obtained with the jo int 286 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-00850R040340050024-7 use of photographs in the blue-green, red and IR (0.82pLm) spectral zones. A densitometric processing of the multizonal photograpFis taken with the MKF- 6 camera: made it possible to determine diagnosLic spectral soil curves a new and important criterion for interpretation of the soil cover. Multi zonal color space photographs synthesized with the! MSP-4 instrimment have great possibilities. Due to the more easily distinguishable color range of the photoimage of the soil cover they give the maximum effect for both outlining soii areas and for the diagnostic interpretation of - soils. 6. A new valuable source by means of which it is possible to obtain infor- mation on the radiated energy of thA soils and plantings in the entire - range of the electromagnetic spectrum is photoelectronic research methods. The data from a radiothermal survey in the range 0.8-3.4 cm were effect- ively used in studying the surface moisture content of soils. An infrared radiometer (operating in the range 8-12 � m) was used in regis- tering several different thermal anomalies of the soil cover in the terri- toYy of the European USSR. Against the backgrosnd of thermal anomalies characteristic for the territories of Steppe Crimea and the Prichernomor- skaya Lowland there was clear discrimination of the colder sectors of al- luvial-meadow and meadow-swamp soils of the lower reaches of the Kuban and Danub e. Against the background of the warmer sectors of the Sal'sko-Man- - ychs kaya Rldge with southern cherno zems and dark chestnut soils it was pos- sible to discriminate colder sectors of the territory of the K�ama-Manych- skaya depression. Side-view radars considerably supplement other methods because this equip- ment operates successfully at nighttime and in the presence of cloud covere - Radar photographs have been used successfully in the recognition of soils and agricultural crops. By changing the signal direction and strength this metho d makes possible an approach to study of the mineralogical composi- tion and penetration into the depth of the soil layer. The use of radar photographs in the territory of Northern Kazakhstan from the moird' pattern of a dark gray tone made it possible to determine dark chestnut sandy and sandy loam soils formed under virgin land grassy vegetation of different _ types; eroded soils were interpreted very clearly from the spotty-dendritic pattern. Visible in contrast on the photographs is the antierosion strip system of agriculture (fields with ar~ alternation of cultivated crops and grasses); fields of bare fallow; fields with plantings of spring grains (wheat, barley) and grasses (crested wheatgrass). 7. For soils-agricultural purposes it is promising to carry out an aero- space survey in diffarent seasons of the year. The early spring period is an important time for studying the mois~ture content of soils using remote - methods. ~The best time for a survey for the purpose of mapping of.,the soil , cover^iahen the soil surface is dried out and the fields are plowed.

The autimmn period is the time for determining the autimmn mois- = ture reserves of soils and study of the state of development of winter - crops and so il mapping. ; Using a space photograph of the territory af the steppe zone (typical - chernozems) for the spring survey pe�tiod there was reliable determination _ of freshly plowed fields and lands on which cultivated crops had been _ sown. Against this background fields of winter wheat and grasses �meadow- ` chernozem sails of steppe ravines and guliies, as well as gray forest soils and sectars of eroded soils and paorly consolidated sands stand out in con- trast. The different character of erosional dissection of soils was espec- = ially reliably determined from the photoimage or this photograph. On a sum- - mer space photograph it was virtually impossible to determine plowed meadow . _ -chernozem soils of depressions in the region of occurrence of chernozem _ soils. Against the image backgroun.d of gray forest soils the degree of _ erasion of the territory is determined clearly. - The time of carrying out the space survey in the course of the day exerts _ a significant influence on the photoimage of the soil cover and sown crops. In the steppe zone in the morning hours of a suxvey from space (June) it - is easy to interpret fields with different sown crops. In a survey at mid- day the gully-ravine network stands out in great contrast. An analysis of long-term changes of the soil-vegetation cover revealed a stable, modified (in part) and highly modified (meliorated territories) - nature of the photoimage of the soil cover. The use of aerial pho*_ographs and space photographs of different survey years for one and the same ter- ~ ritory is affvrding new possibilities for studying the dynamics of erosion- aI processes, objective detection and prediction of changes in the soil = - cvver accompanying melioration work. Routine surveying at different times is the basis for objective inventory- = ing of soils and agricultural crops, their state, development, determina- - tion and pre3iction of crop yields. _ 8. Keys for soil interpretation are prepared on the basis of an investiga- - tion and analysis of the photoimage of th e soil cover of key sectors on aerial and space photographs. They include: - a) aerial and space photographs with the results of interpretation in the - form of a sample of a soil map frequently compiled on a transparent base; _ the photographs and maps are at the same scale and when they are matched it is easy to determine the soil units and the characteristics of their phetoimage; for each photograpli data are given on the scale, time and form of the survey (black-and-white isopanchromatic or infrachromatic; color 2$8 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 "natural" or spectrozonal; mult4zonal, nultispectral with an indication of the surveyed spectral regions; IR, radar); in addition, there is indi- cation of the natural region, in accordance with the soil-geographical regionalization, to which the photograph belongs; b) tables and keys for the interpretation of soils which contain the names of the soils and the properties of their upper horizons exerting an influence on the ghotoim- age (content of humus, carbonates, iron oxide.s, salt3, moisture; mechan- ical composition); coefficient of soil reflectivity; data on relief, vege- tation and geology (soil-forming rocks) and soil interpretation criteria; - explanatory text with a description of the natural conditions and the soil cover and an indication of the peculiarities of soil interpretation of the analyzed photograph; with the use of multizonal photographs there is an effecz from the use of individual spectral zones or their combinations for soil identification. 9. In the present stage of development and use of aerospace methods frr the study of soil resources an important economic effect is noted from the creation and revision of soil maps. The use of these methods makes it pos- sible to compile soil maps which are more precise and more complete in _ content. At the same time, using remote techniques it has become possible _ simultaneously over extensive territories to study the properties of soils - in the field, which earlier was not possibie in research. Ir. the campilation of soil maps from multizonal aerospace photographs with use vf an image analyzer ("Kvantimet-720") there is an increase in the role of pre'Lininary office interpretation of soils and detection of their prop- erties, having great importance for increasing fertility. When samples of soil interpretation and soil maps of a similar or larger scale than the future map compilation are available for the investigated region, a map of preliminary soil interpretation is compiled in the office period and is then refined. In the case of a large-scale soil survey with the use of aerial methods there is a reduction in the number of test pits by a factor of 2-3, with some increase in the r.umber of primary and secondary pits as a result of more complete information on the soil cover which is provided by aerial photo graphs. - It was established that in medium-scale mapping of soils in the dry steppe and desert zones with the use of aerial methods the complete-ness of the content and quality of the ma.ps increase by a factor of 2-3. In tne sriall-scale mapping of soils with the use of space photographs the soil maps were compiled more completeYy with respect to content with an - objer:tive representation of the generalized structure of the soil cover - on tiiem. In comparison with available methods (for the dry steppe and desei't zones) the effect is increased by a factor of 1.5-2. Space photo- grap~,s, as a result of their extensive coverage and the optical general- - ization of details of soil structure, made it possible to interpret and 289 FOR OFFIGIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 FOR OFFICIAL USE ONLY precisely map the complex soil cover of floodplains and deltas of rivers, alluvial fans of mountain rivers, areas of dry channels in the south and inaccessible meadow lowlands in Yakutia, etc. It was established that the - interpretability of the soil cover and the effectiveness of study of soils and the compilation of soil maps of the territory of dry steppe and desert - zones from space photographs is several times greater than in the steppe zone. This is atLributable to the greater contrast of the soil cover and the lesser agricultural exploitation of soils in the deserts and semides- erts. Taking into account international data, especially from the United States, it is assumed that in the study of the soil-agricultural resources each ruble invested in the technology of remote investigations and new direc- tions for their use will give an economic effect five times as great. 10. In the long run, for the effective use of aerospace materials in soil - science and agriculture it is i.mportant to make investigations of the fol- lowing scientific-methodological problems: further evaluation of the information content of aerospace materials on soils and agricultural crops in different parts of the spectrum - from the ultraviolet to the radiorange; further levelopment of ineans for remote sensing of the earth's surface, qualities of soils, condition of sown crops; creation of aerospace interpretation keys for soils and agricultural crops and formulation of criteria for the reliability of office interpret- ation; investigation of the spectral brightness of soils and agricultural crops for the entire range of the electromagnetic spectrum for different natural - and technical survey conditions; formulation of a classification of soil cover images based on study of their texture for the purpose of enhancing the information possibilities of the used materials; study of the peculiarities of the ptotoimage of soils and plantings of agricultural crops on aerospace materials in dependence on survey time and season; development of inethods for the automated (using an electronic computer) computer identification of soils and crops from aerospace photographs. On the hasis of the data collected in study of the soil cover and the con- dition of agricultural crops from aerospace materials it is possible to make an approach to evaluation of tfie fertility of different soils, the yield of agricultural crops and the productivity of mown fields and pas- tures. - 290 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/08: CIA-RDP82-00850R000300050024-7 APPROVED FOR RELEASE: 2007/02148: CIA-RDP82-44850R000300054424-7 BIBLIOGRAPHY 1.
