GEOMORPHOMETRIC ANALYSIS OF THE RELIEF OF AGRICULTURAL TERRITORIES BASED ON REMOTE SENSING DATA

The basis of geomorphometric analysis using Earth remote sensing (ERS) data is the analysis of digital model (DEM). Based on the FABDEM DEM, the territory of the experimental production farm of the Krasnoyarsk Territory was studied, a series of large-scale maps of key geomorphological relief indicators were built: steepness and exposure of slopes, curvature (planned and profile), terrain ruggedness index (TRI), LS coefficient, topographic wetness index (TWI), etc. A geomorphological analysis of the Mikhailovskoye farm was carried out, key morphometric parameters were obtained, which are stored in the form of a geospatial database of the farm. The results showed that the modern FABDEM DEM is suitable for obtaining information about the general topographical features of the terrain both at the farm level and at the level of individual agricultural fields. The use of DEM and ERS allows for a full-fledged collection and analysis of the relief of any agricultural area.
