Calibration corrections for two cameras (N 51 and 216) were 
calculated from six test object photographs (for camera N 51 
in the scales of 1:5000 and 1:10000) not processed by Anagraph. 
Every photo of the 1:5000 scale contained in average 80 points 
of the test area and of the 1:10000 scale - 220 points. The 
field calibration characteristics are given in Table 1. 
Table 2 contains accuracy properties of the photographs 
from test area singular stereopeirs processing by Anagraph 
stereoplotter. The spatial coordinates of control points (mar- 
ked points on the test object) obtained both by geodetic me- 
thods - "true coordinates" (control type "G" in table 2) and 
photogrammetric bridging (control type npr) were used in pro- 
cessing. 
The photogrammetric bridging provides photo processing by 
bundle adjustment with their self calibration. Additional pa- 
rameters are chosen as functions compensating systematic er- 
rors which are selected from polynoms of the third order. 
Block of two strips (14 photos of the test object by ca- 
mera TES-10M N 51 in the scale of 1:5000) with control shown 
on Fig.1 was used for adjustment. Forward photos overlap is 
60%, lateral overlap - 207.
