Interpretation of multiband space images is conducted with 
a selective application of aerial photographs obtained in sub- 
satellite experiments. In oder to identify subtle differences of 
the interpreted objects, not captured visually, for instance, 
those associated with the state of crops, measurement interpreta- 
tion is used, which is based upon the photometric parameters of 
objects' spectral brightness, established from zonal images, 
observing the distortions attributed to the conditions of photo- 
graphy. Spectrophotometric parameters are insured with an error 
of 3-900, 
For a more complicated data analysis, including the 
solution of operational tasks associated with a large volume of 
the processed data, automatized image processing is required, 
whose scope is displayed in the case of compiling maps of land 
use and cotton crops classification depending upon their state. 
A special role, in resolving various tasks concerning 
rather small territories, well studied by the classical methods, 
is played by multiband images taken from aircrafts. This method 
of detailed studies of natural resources and control over the 
natural environment offers a good deal of promise, for instance, 
for GDR's territory. The presented examples of multiband aircraft 
images cover the test site in the area of Lake Sucer-Zee in the 
central part of GDR, and also the areas of Ferganskaya valley, 
the Okhotsk coast and the North-eastern Caspian, the foothills of 
Tarbagatai, where aerial photographs supplement and specify 
interpretation results of space images or are used to work out 
interpretation feature of the objects in space images. 
For each direction of the studies covered by the themes of 
the atlas there are techniques of its own recommended to deal with 
multiband images. The techniques of studying natural resources 
are presented not only in respect of land but also shallow sea 
waters, for investigation of which multiband images provide 
especially valuable data, Due to the fact that rays of different 
spectral bands penetrate in water to different depths, a series 
of zonal images permits successive analysis of bottom representa- 
tion at various depths, thus insuring a way of studying bottom 
landforms, while the use of objects' spectral image opens up a 
way to mapping soils and bottom vegetation of shallow waters. 
The atlas contains the results of the complex study of the North- 
eastern Caspian's shallow zone from multiband images in the form 
of a series of thematic maps in geomorphology, bottom sediments, 
underwater vegetation, underwater landscapes. Such maps have been 
produced successfully for the first time and they are a convincing 
proof of the wide scope of mapping the shallow shelf opening up 
when using multiband space photography. 
When analysing the image of the Baltic sea's coast and 
shallow zone, it became possible to draw conclusions as to the 
dynamics of the underwater topography-formation of bars, sub- 
mergence of islands, and also to estimate the efficiency of the 
storm protection measures undertaken previously and to offer 
recommendations concerning reconstruction of navigable sea 
channels affected by sand drifts. 
In geomorphological mapping, the "spectral image" of the 
photographed objects does not turn™to be decisive either; what is 
really decisive is some by-effects of multiband photography, Jjust
