The article substantiates the approach to analyze the impact of natural and economic (anthropogenic) factors on the terms of functioning of river-basin system Bystrica (right bank tributary of the Dniester, Ivano-Frankivsk region) and its geoecological condition. The display of the feature properties of river-basin system, factors that were affecting her, were characterized on a series of copyrighted thematic digital maps – components of geo-environmental atlas of the river-basin system. In particular, the article illustrates these copyrighted digital maps: the density of Bystrica river basin network; Average annual runoff modulus in the basin of Bystrica; Average annual temperatures in the basin of Bystrica; The fraction of arable land in the basin of Bystrica; The fraction of residential area in the basin of Bystrica; Route density in the basin of Bystrica; River Bystrica subbasins traffic load. These maps reflect geospatial variation of human impact on the river-basin system. They largely explain the scale of degradation processes display in different parts of the river system, as well as revealing the causes of the deterioration of geoenvironmental state of different parts of the basin and river beds of various ranks. The analysis of maps allowed to receive the parameters of the impact of natural and anthropogenic factors on the river system and to assess the extent of transformation processes of that occurred in the structure of the river basin in the 20th century. This information is to be taken into account when compiling complex digital maps of the atlas. Keywords: river-basin system (RBS), geoenvironmental condition, geoenvironmental atlas, factors that impacts the conditions of RBS, thematic maps.
