Abstract
The article presents a technique for identifying structural elements and details of the geological structure in digital terrain models (DTM) based on the theory of scale spaces. With its help, linear, domeshaped and textural features are singled out from medium-resolution DTM (for example, SRTM03, GMTED2010), allowing to significantly improve the quality of studies related to tectonic and geological mapping and zoning. In general, the theory of scale — spaces is described in application to the solution of these problems and illustarted on the examples of a number of case studies.
