The application of the scale-space theory for medium-resolution DTM in geological and geotectonic studies

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, dome-shaped 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.
