The analysis of the study of water erosion of soils on the territory of the West Siberian Plain using geo-information technologies (GIS) and Earth remote sensing was carried out. It is shown that GIS and Earth remote sensing are not widely used in erosion studies in Western Siberia and are used by a limited number of modern researchers. However, the use of digital technologies in this area is characterized by the coverage of almost the full range of their capabilities and functions: digital mapping, the formation of spatially-distributed thematic databases, monitoring, space-time analysis, modeling, automated mapping. The bulk of such research is concentrated mainly within the Novosibirsk and Omsk regions, in the Altai Territory, and to a lesser extent in the Tomsk and Kemerovo regions. Digital technologies for studying water erosion in Western Siberia are more often used to study the dependence of water erosion on its determining factors (mainly topography), the effect of water erosion on soils and soil cover, in morphometric analysis of the relief, land classi cation and mapping. The problem of remote monitoring of the temporal dynamics of water erosion and related changes in topography, soil cover, soil properties, etc. is practically not dealt with. The issues of geoinformational modeling of water erosion in terms of elaboration of detail and scale, and coverage of a larger number of areas require further development. When modeling water erosion, the nature of surface runoff is not always taken into account. The approach to the selection of criteria for the assessment of erosional land at different scales of their mapping is not entirely clear. It remains an open question to develop a methodology for the automated calculation of standards for permissible erosional losses of soil. In general, the use of Earth remote sensing and GIS facilities in the study of water erosion in the soils of Western Siberia is not systematic and comprehensive. This is con rmed by the presence of a number of problems in the study of water erosion in the given area, which requires a digital approach to their solution.
