control points should not exceed 
4 bases. 
a) Mean planimetric error (in the 
map) of basic ground control point 
should not exceed = O,1mm in the | 
map. 
b) Mean square error of planimet- 
ric coordinates of points for 
orientation of stereopairs in ste- 
reophototriangulation on the scale

country should not exceed x O, 35m
