Modern methods of studying inaccessible mountain relief with GIS technology

Abstract

The application of these methods, in addition to remote means of studying the Earth’s surface,
makes it possible to carry out complex studies of the modern condition of mountain ranges
and mountain villages. The development of such a system is complicated by different levels of
accessibility information for each key site, so creating a project GIS that concentrates data on
a single cartographic basis with an appropriate database for subsequent automated analysis
of this information is the most effective way to address assigned tasks. On-based SRTM DEM
using GIS technology performed morphometric analysis of relief Shinchay-Damiraparanchay
mudflow basins. With these purpose-built maps of hypsometry, slopes, aspect, range relief and
drainage density, indexes, dissection and ruggedness, and surface curvature. Also analyzed the
areal distribution of these parameters by grade. Now, in connection with the development of
digital technologies and the broad availability of data of remote sensing, detailed assessment
of relief became possible. Application of the digital models of a relief (DMR) considerably
simplified the morphometric analysis of a relief.
