interpretation o-f remote sensing data of natural environment 
which are based on models of the theory of image estimation 
and identification are characterised by low reliability of 
discerning objects. The main shortcomings C21 of these 
methods, as pertaining to the analysis of images, are 
connected with presentation of images, in the form of the 
vector of intensities (coefficients of spectral brightness 
or optical densities). Given such presentation of the image 
the nature of relationship between its components is not 
taken into account. In connection with this it is essential 
to set the task to describe multidimensional (multispectral) 
image so tl'iat the structure of r el at i onshi p between signal s

In accordance 
wi th 
the first proposition 
of 
the STS 
by 
Y. A. Urmantsev 1 ; ansformation of compositions of primary 
elements can be realised by means of changing only the 
number of primary elements, or only the primary elements 
themselves, or only relationship between primary elements, 
or combining all these ways. Seven main ways of forming 
compositions have been established. And, homogeneous 
compositions are formed only hy changing primary elements. 
The other six ways are used to form heterogeneous and 
hierarchical (heterogeneous—homogeneous) compositions.
