Abstract. The geoinformatic mapping of erosion geomorphologic systems is based on both traditional methods of cartographic representation of information and specific opportunities of computer mapping complexes, including those for analytical processing of data of different types. The study of the characteristics of the erosion geomorphological systems is carried out with the use of aerial and satellite imagery and is based on the results of their geomorphological, geobotanical, soil reclamation, erosion and other surveys. Spatially distributed input data of landscape model should be set as raster electronic maps that characterize relief, soil cover, type of agriculture, vegetation on the catchment area, as well as, morphometry and hydraulic resistance of the channel and floodplain, and also as a set of the attributes describing their characteristics. The use of digital model of relief (DMR) while geoinformatic mapping provides the determination of both planning characteristics of the relief and profile ones, including the values of slope angles, inclination, expositions, slopes configuration, etc. As the result of the modelling, the digital maps of flow, outwash and accumulation, and table data defining the process of flow, outwash and water turbidity, as well as, their final values with the use of large-scale topographic and soil maps, and space imaging of high resolution, are developed.
 
Key words: theory, geoinformatic, mapping, erosion, geomorphology, landscape, model,degradation, outwash, space images.
