The article presents the results of a landscape-ecological study with mapping of the territory in the central part of the Patom upland. Research polygon is located within the Kropotkinsky mining unit of Baikal region, has an area of 600 km2. Technogenic disruption has a wide spatial and temporal distribution. Analysis of a complex ecological situation requires a rational assessment and adequate mapping. For this, modern geoinformation-cartographic, remote methods and a geosystemic approach were used. A large-scale thematic map was created, which includes 250 polygons in the main layer, which belong to 26 types of landscapes. A detailed description of the landscapes is given in the map legend. There are indicated the belonging to the landscape structures of regional and continental dimension, types and degree of disturbance. Additional vector layers are selected for displaying exogenetic geological processes, linear disturbance, geochemical anomalies. Mapsemiotic method was used for the visualization and formalization of the final thematic map. It allows to make full use of the integrated capabilities of the syntax of the map symbols and their semantic value in the software environment.
