New Approaches to the Display of Permafrost Landforms on Digital Topographic Maps of the Siberian Arctic Zone

Abstract

The analysis of traditional topographic maps and plans of the Siberian Arctic zone shows that their relevance and completeness of content do not fully meet the modern requirements for the further de-velopment of this region. There is a need for targeted specialization of a new generation of topograph-ic maps and plans of Arctic territories, taking into account their physical and geographical specifics. The purpose of the work was to determine the possibility of such specialization based on the use of remote sensing materials from space and computer technologies.To achieve this goal, studies have been conducted to determine the visual and automated decryption capabilities of Landsat Sentinel sat-ellite images in order to expand and refine the existing system of conventional signs of cryogenic re-lief. Based on these studies, new conventional signs for polygonal, bumpy, solifluctional and thermo-karst forms are proposed. The conclusion is made about the need for specialization of other specific elements of Arctic maps – vegetation, hydrography, soils.
