Mapping the maximum snow reserves in the Altai region using GIS technologies

The article is devoted to mapping the maximum snow reserves in the Altai Region using GIS technologies. With the help of GIS technologies, the authors created a series of electronic and printed maps reflecting the spatial distribution of water reserves in the snow cover. Creation of maps was carried out with the help of GIS ArcGIS 10.4.1 for Desktop company ESRI. Based on the analysis of the content of the maps, a zone of maximum average annual snow reserves has been identified in the direction from the northeast to the southwest of the territory due to an increase in the altitude of the terrain, a decrease in the aridity of the climate, and changes in the composition of the vegetation cover. Based on the analysis of the content of the maps, a zone of maximum average annual snow reserves has been identified in the direction from the northeast to the southwest of the territory due to an increase in the altitude of the terrain, a decrease in the aridity of the climate, and changes in the composition of the vegetation cover. In the western part of the region, snow reserves are decreasing in the steppe and forest-steppe landscapes of the Priobskoe Plateau and Kulunda.
