Morphometric analysis of the relief of the Povcha Upland

Abstract

The interest in the Povcha Upland is not accidental. There has been almost no specialized research and the existing stock information does not reflect the real situation of modern relief; there is a need for more detailed research. Morphometric analysis of the relief is one of the most effective methods for its study. The use of GIS technologies and digital elevation models makes it possible to create thematic maps of the most essential morphometric relief indicators. Methods of digital elevation modelling were used during morphometric relief analysis. It allowed us to characterise this area by quantitative and qualitative indicators of relief. The key morphometric indicators of the relief of Povcha Upland are highlighted. A series of morphometric maps was made using ArcMap. Based on the digital elevation model of SRTM using GIS, the complex morphometric assessment of the Povcha upland territory is executed. Maps of hypsometry, slopes, aspect ratio, range relief and drainage density are constructed. Key words: Povcha Upland, digital elevation model, morphometry, hypsometry, slope, aspect, horizontal dismemberment of a relief, vertical dismemberment of a relief, GIS.
