Digital Terrain Model as a Basic Element of Corporate GIS (Using the Example of the Toratau Geopark)

The scientific article is devoted to the study of methods for obtaining three-dimensional terrain models using modern technologies of remote sensing of the Earth. Various techniques are considered, including interpolation of elevation points and isolines, the use of satellite images and lidar photography by means of unmanned aerial vehicles. The arguments in favor of using lidar photography to create a digital terrain model in the context of creating a corporate geoinformation system for the Toratau geopark are presented.
