The possibilities and limitations of SAGA GIS for processing DEM and remote sensing materials of free access in the interests of specialized mapping of debris flow hazard in the Baikal region are considered. The results of processing the SRTM and ASTER GRID DEMS, as well as the spectrosonal images obtained from the Landsat-8 and Sentinel-2 satellites in the SAGA environment are compared. The most effective tools of GIS-analysis of territories from the point of view of the potential hazard assessment of debris flows based on remote sensing data are determined.
