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. There were some 20" theodolit~"s and one second theodolite

located on the sides of certain buildings, usually a church or university.
The bench mark was a metal ball imbedded in concrete. 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.

The limits of error depended upon the class of terrain,
of which there were five. Fifth class terrain was-ideal; first class was

terrain. The allowable error was -t one in 2,000. In fifth class terrain,
the allowable error was : one in 15-20,000.
