There were surveying schools in Kharkov and Dnepropetrovs 50X1-HUM The surveying wds,very simple because the oblast geodetic group gave the easiest and dirtiest jobs to the rayon. The rayon group consisted of about 20 administrative people and surveyors. surveyed three kolkhozes: Andrievka, Pryslav and Vychyslavka, all near Berdyansk. surveyed small plots of land near Kowel. Surveying for roads and buildings was done by the oblast geodetic group, and cartographic surveying by a higher agency. at the rayon geodetic group headquarters a 30 second tlheodoli was manufactured in Leningrad. The name plate did not give the date of manufacture. This instru- ment was difficult to use as the gasifying lenses used to read the scales were of very poor quality. used a 20 second theodolite of German manu- fac:t,ure (Otto feln). used both Dumpy and Wye type levels. These had no markings to indicate place of manufacture. some instruments of Polish origin.

These points were located and numbered on the plans of the city which could be obtained from th, burgermeistera If you wanted to use one of these bench marks., you had to go to NKVD headquarters and tell.them the number of the bench mark in which you were. interested. They would then investigate why you wanted to know and if you had the authority to have this information. If you passed the investigation they would tell you the latitude, longitude and eleva- tion of the marks in question. In the country, the bench marks were square wooden posts, about 8" on a side, about one meter in the ground, and about 30 cm above the ground. There was a crosspiece on the bottom to make it more stable. Each bench mark had a number which had to be given to the NKVD to obtain the necessary data for its use. 411 /,,,777777- FRONT VIEW 6. The limits of error depended upon the class of terrain, of which there were five. Fifth class terrain was-ideal; first class was very rugged. =surveying was done in what was considered fourth class terrain. The allowable error was -t one in 2,000.
