Application of geoinformation technologies in the study of landscapes. (on the example of the construction of a digital model of the relief of the North-Western Caucasus)

Relief is a structural unit of the landscape, a change in the relief inevitably leads to changes in the natural-territorial complex. At present, the landscape is experiencing more and more anthropogenic influence on the part of man. In this situation, the study of the structure of the relief is an important factor and the study of the state of landscape complexes. The most suitable tool for this is space-based imagery of the Earth’s surface, which was obtained from the satellite by the Landsat system. Based on the Landsat data, you can build a digital model of the terrain of the study area, which is a three-dimensional image of the terrain of the earth's surface.
