significantly superior than MKF—6 due to the fact 
that the space base is 3.3 times larger, the quality 
of the film levelling is bettter and the value of 
coordinates in difference from MKF—6 is standardized 
at h— 9 mem. 
The ground resolution of that data reaches 6 
metres for the compact objects and even 4 metres if the 
contrast ratio between the object and the background 
is high. The line and long objects of 3—5 metres wide, 
and sometime for contrast objects of 2 metres wide 
can be surely interpreted. 
The combination of large visibility with high 
resolution allows to use this kind of space 
photosurvey for enhancement of wide field of problems 
— from the global to local and detailed. 
By the results of photometrica1 measurements 
the accuracy of the altitude dedtermination by MK—4 
camera photoimages is characterized by medium square 
error of 9.8 m. 
The shown samples of photo pictures demonstrate the 
examples of interpretation of photoimages acquired by 
MK—4 camera.
