Refinement of the pattern of geological 
boundaries is carried out taking into account the 
phenomenon of natural generalization of the 
image in transition to smaller scales. This 
phenomenon manifests itself in two ways. In the 
first case an area of development of formations 
overlapped by a cover of loose deposits seen in 
the images is increasing. This increase 
apparently results from the fact that in the 
transition to the smaller scales thin loose 
deposits do not serve already as a screen for the 
manifestation of typical interpreting features of 
buried formations. In the second case several 
contours are integrated into a single contour 
which corresponds to the really mapped 
geological body of definite composition. 
Revealing the peculiar features of 
petrological composition and inner structure 
of mapping objects is an important moment of 
the employment of RSM in geological 
cartography. At this stage of great significance is 
the analysis of spectral characteristics of the 
bodies distinguished using RSM as well as 
specific features of the structure of the lineament 
field. It should be borne in mined, however, that 
the determination of petrological composition 
from the results of interchannel transformations 
is possible only under favourable conditios, i.e. in 
arid well-exposed regions. Such conditions are 
not characteristic of the territory of Russia. In this 
connection expert systems for the determination 
of  petrological composition developed at 
VNIIKAM (LITHO software package) are 
increasing in importance. Under conditions of 
insufficient exposure these systems provide 
interpolation of data of field observations on 
reference outcrops and key areas for the rest 
mapping territory. :

Combination of geological-geophysical data and 
data of remote sensing methods at every stage 
of map compilation and their integrated analysis 
are carried out by ERDAS and ARC/INFO 
software. 
4.3 Compilation of the final map 
The completing operation is compilation of the 
final map. All the objects first distinguished using 
RSM and confirmed by geological and 
geophysical materials can be treated as reliable. 
They are represented in the map by established 
symbols. Ambiguously interpreted objects can be 
shown as assumed ones. 
5. CONCLUSION 
This technological scheme which incorporates 
the integrated analysis of RSM and geological 
data, their mutual correlation and correction of 
the obtained results at all stages of map 
compilation provides informative character and 
high quality of the map.
