cent re by proffessional staff /geologists, soil interpreters, foresters, geo- 
desists/. They are mainly concerned with interpretation and delineation of 
different specific categories. Interpreted information is properly marked on 
photography and technical report is made for each teritorial unit. 
The results of research on selection of apropriate scales and techniques 
for interpretation of different basic information are shown on table N' 1. 
Techniques for interpretation are mainly visual. In order to obtain a stereo 
impression mirror stereoscopes are used. 
For specific interpretations /plant desease detection, water polution, etc./ 
where larger resolution is needed a density slicer ISI 130 is adopted. Its 
output allows objective interpretation and immidiate computation of density.
