Fig.1. Scheme of horizontal and vertical 
control points in the block 
errors in comparison with geodetic positions* are 4.2 sm in 
horizontal plane and 4.4 sm in vertical plane. 
The version number means the following: O - errors of image 
and model are ignored; 1 and 1* - with the use of field and 
self calibration results respectively; 2 - model distortion is 
compensated by polynoms (multiquadrics); 3 - results of the 
field calibration combined with multiquadrics. 
In all mentioned above versionssimultaneous relative and 
absolute orientation of photos and model by 9 control points 
arranged as on Fig.2 is carried out by Anagraph stereoplotter.

points choice on the stereopair area 
To estimate the accuracy of model RMS errors of the spati- 
al coordinates were determined as the difference between the 
calculated and geodetic coordinates of the test area check po- 
ints 
  
* - RMS error of geodetic positions of the test area marked 
points center coordinates is 2-3 sm in the plane and not 
more then 1 sm in height
