provided for them. In this way all polymorphic modifications
of compositions are examined, i.e., compositions formed by
viirioub complexes of intensities. The vector of the
inter dependency between variables in composition, and is
called the c omposition c od e.
Properties of the model. The composition code as a method
of description of information structures is based on sets of
various combinations of fields. It determines relationship
between them in various intervals of values, and therefore,
is a differential information model of geoinformation
structure. The code represents a complex criterion with high
dividing capability and is good for differentiating non-
homogeneous information structures. The maximum number of
-lasses into which the ex amined informa11 on field can be

— the code includes both general and specific features
of classes of objects;
— the quantitative characteristics of the image is made
as a composition of features specific for the image;
— the law of composition is the main criterion of
discerning the object within the environment;
represents the structure of the objects, not the structure
of their boundaries.
Application of the model. Being an abstract one the
relationship between signals (signatures) has no limits as
