Glacier Degradation from GIS and Remote Sensing Data

摘要

Application of the multilevel geoinformation system is focused currently on estimation of danger from mudflow and monitoring the mudflow processes. Within the limits of southern coast of Lake Issyk-Kul (from Ton in the west up to Kyzyl-Suu in the east) the analysis of glaciers and the potential for forming mudflow risk has been performed using remote sensing and GIS technologies. Features of freshet and mudflow dangers for the Tone valley differs other regions. Also quantitative assessment of linier and aerial changing is conducted. Sustainable reduction of glaciation and the rate of degradation in various volleys are estimated.
