Morphometric analysis of the relief in the assessment of soil erosion

Abstract

Morphometric analysis of the relief is one of the most effective methods of its study. The main sources of information for digital terrain modeling are large-scale topographic maps, materials of field instrumental surveys, as well as data from remote sensing of the Earth. The use of GIS technologies and digital terrain models makes it possible to create thematic maps of the most important morphometric relief indicators. There was carried out a morphometric analysis of the M&A relief using the digital relief model Alos Polsar Dem 12.5m, based on which derived models have constructed a hypsometric map, maps of slope angles, and slope exposures.
