Watkins Director, EROS Data Center Sioux Falls, South Dakota 57198 DDI-~ ..&.,~. _ yls 2 2 AUG 1985 One of my imagery scientists) I is pursuing a program of independent research on methodologies to combine data from various satellite imaging systems. This study is being conducted under the auspices of the Intelligence Directorate's Advanced Analyst Develo ment Program. As the initial part of his program, would like to spend a two-week period (14-25 October 1985) with the Technique Development and Applications Branch at the EROS Data Center (EDC). The principal objective would be to investigate the feasibility of developing digital relationships for the NOAA LANDSAT and meteorological satellites that would permit interchangeable use of hardcopy and CRT images. Workin with the image data processing experts at EDC would broade expertise and provide him with a better understanding of the technical issues related to the integration of data from systems with different spectral and spatial characteristics. Facilities at the Data Center provide both digital processing and image production capabilities suitable for his work. Further, EDC personnel are familiar with unique Agency LANDSAT image processing requirements. The Directorate of Intelligence, of course, would provide-all funding and administrative support for during his study at the Data Center. ?

Since this com- bination is more compatible in spec- tral range to MSS bands 1, 2, and 4, the standard TM false-color com- posite provided by NOAA will now be made using TM bands 2, 3, and 4 with new photographic look-up tables. This report traces the evolu- tion of the methods used to achieve the color products now available to Landsat users. Its purpose is to in- form TM data users of NOAA's progress in establishing a compatible TM/MSS color balance characterization. This color balance scheme will be applied to all archival photographic products produced after July 1, 1985. Background The TM was conceived by NASA as a second-generation instrument relative to the Multispectral Scanner System (MSS). As such it was prin- cipally designed to observe vegeta- tion cover and provide a better measure of crop acreages in regions or countries with small fields. To aid in this assessment, a 30-meter spatial resolution was adopted along with some "sharpening" of the spec- tral bands. Landeat 8 Thematic Mapper scene of Washington, D.C. area generated using the new photographic look-up table (Band 4). Scale, approximately 1:1,800,000. Displayed is the central portion of scene 80099-18143 (Engineering roll 8811983), acquired in June 1984. The objective of early TM image evaluations using data acquired from Landsat 4 was designed to characterize sensor response and verify the utility of the TM for special applications. These studies were carried out by principal in- vestigators funded by the NASA Science Office. Most principal in- vestigators performed digital analyses using single scene data ac- quired over predetermined areas of the Earth's surface. Scientific results for each scene were categorized using digital data analysis techniques for the single acquisition received. A series of applications results were derived by these investigators. All results were taken from Landsat 4 acquisitions in the fall of 1982. When color composites were required to illustrate a point, they were generated through the use of special photoprocessing techniques to enhance specific features in each scene. Multitemporal investigations were also planned and funded. However, the priority of these investigations was reduced when the Landsat 4 TM was effectively lost February 14, 1983 (approximately 7 months after launch) due to a combination of the loss of the X-band transmission capability and the eventual failure of two of the four solar array panels. Prior to this time, 11,000 TM scenes had been acquired worldwide. Ap- proximately 8,000 of these covered the USA and were candidates for pro- cessing. However, due to the lack of a high volume production facility at the time of launch, the data on hand were processed on an alternate system capable of only one full scene each day of operation. This limita- tion resulted in very selective image processing. Furthermore, since there were no TM scenes available from Landsat 4 that were acquired during the spring and early summer grow- ing seasons, the film look-up tables (see September 1983 Landsat Data Sanitized Copy Approved for Release 2011/09/13: CIA-RDP90G01359R000200010011-5 Sanitized Copy Approved for Release 2011/09/13: CIA-RDP90GO1359R000200010011-5 Users Notes) were applicable only to fall acquisitions. Transition to NOAA Landsat 5 was launched on March 1, 1984, at which time the NASA Thematic Mapper Image Processing System (TIPS) was in the final development phase and capable of only limited operation to support research and development. TIPS was to produce twelve full TM scenes per day for the archive, with this throughput volume of data to be in- creased significantly after the development phase was completed. Prior to the transition of TIPS to NOAA on September 1, 1984, all ac- tivities associated with ground pro- cessing were directed toward assur- ing that the complex of hardware and software required for TM opera- tions met production throughput goals. As a result of these priorities, no attempt was made by NASA to op- timize color balance. Initial attempts by NOAA to make Landsat 5 MSS and TM photographic images look alike using TIPS were not totally successful for data ac- quired in any season other than fall. False-color composite images generated using black and white TIPS transparencies from bands 2, 3, and 4 were poorly suited for agronomic analysis. The images had an overall bluish cast; subtle vegeta- tion stress signatures were not as evident, and the effects of soil moisture were more difficult to discern. Other users, accustomed to the MSS color scheme, also found the TM images unsuitable for their ap- plication when established inter- pretation criteria were applied to the photographic data. Subsequent analysis of the problem indicated that, with modification to the film production system, MSS and TM im- ages from TIPS could be made to have similar color balance. Color balance nearly identical to MSS "bench mark" images was achieved through the remapping of TM digital values. The remapping was based on a Landsat 5 data set consisting of several portions of a late June 1.984 agricultural scene ac- quired simultaneously by MSS and TM. The scene included large fields, extensive forested areas, multiple cultural features and a variety of different vegetative cover types. Also, due to localized drought condi- tions and the presence of some ir- rigated fields, a wide range of crop conditions was evident. Sample sizes were selected from ten different scene components to provide a wide range of spectral data. The sample sizes ranged from 400 MSS pixels for cultural features to over 22,000 pix- els for forested areas. Data for each common area were extracted from computer-compatible tapes for both MSS and TM. These common data were remapped from TM to MSS equivalent digital values through using a linear regression. Using these data, a new photogra- phic look-up table for Landsat 5 data was created. This table (Table 2) should be contrasted with the earlier result (Table 1). Note that in Table 1, the look-up table values for bands 2 and 3 were the same at each step and bands 4 and 5 were equivalent in the same manner.

Furthermore, in each of these bands, the photogra- phic response curve shifted away from the original shape presented in 1983. Figures 1 through 16 have been prepared to illustrate the difference in black and white photographic pro- ducts when the new look-up tables are applied. Each group of four figures contains two images and two plots. These figures were generated for a scene containing coverage of Kemmerer and Green River, Wyom- ing (southwest corner of state). This scene (path 37, row 31, from June 18, 1984) was selected for this analysis because of its wide variety of ground feature types.

For example, Figure 3 is the curve used to generate Figure 1 and, similarly, Figure 4 is the curve used to generate Figure 2.

The MSS data were acquired at the same time as the TM data and are representative of the data archived for this scene. Comparison of these figures illustrates that this more re- cent version of TM color is a close match to the MSS product. In order to pursue this point, an expanded data set was considered. Figures 20, 21 and 22 are presented to provide information relative to how these transformations improve data acquired over desert regions. Multi-temporal and multi-satellite data are illustrated in Figures 23, 24, 25, and 26. These figures contain false-color composites for TM and MSS from Landsats 4 and 5. Figures 23 and 24 should be compared for TM to MSS color balance as should Figures 25 and 26.

Furthermore, comparison of Figures 23 and 25 illustrates the multi-temporal color change to be ex- pected with TM. Figures 24 and 26 il- lustrate this same effect for MSS. In summary, it can be stated that this set of look-up tables for TM bands 2, 3, and 4 produces both black and white and false-color com- posite images that have more defini- Figure 8 - Landsat 5 Thematic Mapper scene using new photographic look-up table (Band 2).

These tables will be applied to all photographic data processed after July 1, 1985. Com- puter search listings for these data will be marked with "NOAA RAD LOOK UP NO. 1." On a related note, NOAA wishes to remind users that developmental work continues on black-and-white TM scenes over areas of very low or high reflectance. As pointed out in the December, 1984 issue of this publication, there is concern over a lack of sufficient contrast in such TM scenes.

NEW STANDARD TM COLOR COMPOSITE As indicated in the lead article, the standard TM false-color com- posite indicator in the Landsat data base has been changed from Bands 1, 3, and 4 to Bands 2, 3, and 4. This change was made to assist the user community in comparing MSS and TM data. The choice of Bands 2, 3, and 4 from the TM sensor more close- ly represents the spectral regions that MSS users are familiar with from MSS color composites of Bands 1, 2, and 4 (Bands 4, 5, and 7 for Landsats 1, 2, and 3). The flags of the existing Landsat 4 and 5 TM color composites have been changed in the data base to reflect this. In addition, the research or computer inquiry function has been modified to flag the existence of non-standard color composites as follows.

In the computer inquiry printout, the color composite field will contain a number if a standard composite ex- ists; this number is an assigned color composite quality indicator. If the standard composite does not exist but a non-standard composite does, (for example, a Band 1, 2, 3 "natural color" composite), then the field will contain the character "U" for uni- que. If neither exists, the field will contain a "P" for possible; that is, no Figure 16 - Plot of TM Band 4 density transformation curve used to create Figure 14. color composite has been attempted, but could be. An "N" indicates that a color composite cannot be made. NOAA expects that this change to the TM data base and the upgrade to the research capability will assist our TM customers. TM PRODUCTION GOALS AND ARCHIVE HOLDINGS NOAA has established the follow- ing production goals for the Thematic Mapper Image Processing System (TIPS): 25 film scenes and 10 CCT scenes per day, 7 days a week. The TM HDT-A archive at Goddard Space Flight Center contains approx- imately 50,000 scenes of Landsat 4 and Landsat 5 data at various levels Sanitized Copy Approved for Release 2011/09/13: CIA-RDP90GO1359R000200010011-5 Sanitized Copy Approved for Release 2011/09/13: CIA-RDP90GO1359R000200010011-5 Figure 17 - TM false-color composite of Bands 2, 3, and 4 generated using the old look-up tables (Archive roll 8420001.)

Production of TM data for customers and the film ar- chive has resulted in 6948 TM scenes produced by April 30, 1985. These products are archived at Sioux Falls as follows: TM CCT Quads Corrected (P data) Uncorrected (A data) Landsat 4 971 136 Landsat 5 6,151 643 TOTAL CCT QUADS: 7,122 779 As NOAA has gained production experience, certain timelines have emerged. For acquisition data, the timeline from satellite passage to the entry of archive data at Sioux Falls has been about 20 days. This is a reasonably acceptable timeline based on the data collection and distribu- tion system in place. For retrospec- tive orders, turnaround performance is somewhat higher for two reasons. First, TIPS is structured to process data in continuous swaths rather than as single scenes. Secondly, older data, especially those acquired before September 1, 1984, have proven dif- ficult to recover and process. NOAA management intends to continue to refine the system so that customers can receive data in the quickest possible time.

Microfiche will re- place the standard 16mm B&W roll microfilm. The change is being made for TM and MSS data processed after January 1, 1985. The new format will be less expensive ($20 per set of 1200 scenes versus $60 for a micro- film cassette of 1200 scenes) and it will be delivered much sooner than the roll microfilm has been. The mi- crofiche image reference system will not change - scenes will continue to be randomly packed on the micro- fiche and be retrievable only through an INORAC or microCATALOG in- quiry. The new microfiche references will be distinguishable from the roll film microform locations within the inquiry listings by a "D" prefix (D7902310808, for example) instead of the roll film "B" prefix. The range of microfiche locations for each image is noted in the upper left-hand corner. Each fiche holds 60 images. Each set is exclusive to one sensor type (MSS or TM) and has a uniquely-colored header (fiche title strip) throughout the set. Sequence numbers are in the upper right-hand corner to minimize filing problems (1 of 20; 2 of 20; etc.). In Figure 1, the microfiche image set number is D790231 and the frame or location is 0808 which will be on card 14, col- umn 8, row 3. (See Figure 2). The microfiche image sets are available in two forms: as a single set (20 cards/1200 scenes) and by calendar year subscription, January through December (20 cards/1200 scenes and as many sets as are pro- duced in the calendar year). The cost for a single MSS or TM set is $20.00. The cost for a calendar year subscrip- tion of MSS data is $500.00. The calendar year subscription cost for TM is $100.00. The MSS microfiche images are Band 2. Microfiche TM images are Band 3 or 6 (night-time data). Regardless of order date, all subscriptions will run from January through December, ensuring receipt of a full year's data. Single microfiche image cards are not available for sale or distribution.
