The paper describes the experience of a digital geoecological map compiling of one of the largest geological and industrial areas of Russia. Western Siberia geoecological maps were compiled in 1990's using a traditional manual method on the regional ecological research results of 27 nomenclature sheets of a scale 1:1000000 of an international listing. The concept of the digital geoecological map content was designed, the general principles of the legend making were updated, and the methodical advises on the digital model structure and the attributive information databases were formulated. The unified digital map satisfying to all requirements of GIS is the digital theme map basis. The geoecological map is informational digital model consisting of four theme items, describing the geoecological condition of a region on definite set of mapped parameters. The complex estimation of geoecological condition of the region is given as an integral criterion defined with GIS ArcInfo. The offered technology of creating the Western Siberia geoecological map as a digital cartographic model on the basis of GIS-technology, will allow to receive sets of the new digital specialized theme maps, to provide their constant actualization, to estimate the geologic environment condition.
