The experience of the joint processing of photographic 
and radio-thermal images of terrain has revealed high re 
liability of the obtained results and confirmed the avail 
ability of rich information on other invisible phenomena. 
Even today the development of optimal procedures for ex 
tracting this information, including that contained in 
the aerospace photographs of the visible and infrared 
ranges is a most topical problem.
