Abstract SRTM 4.0 data with a spatial resolution of 30 m were selected as the basis for the digital elevation model (DEM) for the territory of the Republic of Adygea which was built for the first time. A comparison with different topographic maps of different spatial resolution showed that the elaborated DEM of the Republic of Adygea is very accurate. Slope gradient was calculated for the territory of the Republic, which allowed to show possible applications for agriculture, analysis of hydrological network and different exogenous processes, and planning of road construction. With a variety of landforms and the development of exogenous geological processes, the creation of a DEM of the Republic of Adygea integrated into the GIS is necessary for geomorphological zoning and landscape science, geological and soil erosion studies, construction of visibility zones for telecommunication and GSM companies, carrying out cadastral valuation of land and urban development, risk assessment of landslides and avalanches, planning of wind and solar farms, development of mountain tourism and ski resorts, and many other tasks.

1 Introduction Relief is one of the main factors that determine the course and direction of processes occurring in the surface layer of the planet. In particular, the relief is one of the main factors in the lateral transfer of water and other substances along the earth’s surface and in the soil under the influence of gravity [1–3]. It largely determines the climatic and meteorological characteristics that affect the hydrological and thermal condi
