The spectrozonal (multizonal) aerospace survey methods 
are among the most informative methods in the Earth remote 
sensing. But possessing certain known advantages they do 
not enable many-sided investigations of the object being 
sensed, for instance, its internal structures, due to low 
penetrating power of electromagnetic waves of this wave 
length range and the effect of various atmospheric factors 
on their propagation. 
To widen the sphere of effective use of the materials 
of these surveys it is necessary to attract the data ob 
tained by other all-weather methods operating in the wave 
length bands possessing certain amount of penetrating power. 
These advantages are characteristic for the radio-phy 
sical remote sensing methods, and in particular the micro- 
wave - radiometry methods. 
Let us consider in the theoretical and practical-ap 
plication aspects the possibility of joint use of radio- 
thermal and spectrozonal (multizonal) images for increasing 
the amount of information contained in the latter. Such 
problem may arise in refining boundaries between the out 
lines (for instance, ’’land-water’ 1 ), in discriminating 
boggy areas of terrain, in topographic survey of objects 
covered with snow or ice (for instance, in mapping the 
Antarctica), in assessing fire-hazardness of forests, mak 
ing the special thematic maps, etc.
