From this follows that in practice the digitalization 
with a pixel size of 10 (am leads to a significant loss of 
information in case of MK-4 and MKF-6 photographs. In ge 
neral the MKF-6 photographs are not suitable for detailed 
digital processing. 
Because of both the loss of information content and the 
high amount of data (hundreds of MBytes by one image 
only) the processing of space photographs by means of 
optical-analogical methods will be a suitable matter in 
the future too. At present these technologies are avail 
able on a high professional level.
