We describe an investigation that combines space-based observations of glacier parameters with historical glaciological data derived by traditional means to predict changes in ice extent and volume for the Ak-shirak Range in the interior Tien Shan of Central Asia. A variety of geographic information systems and photogrammetric tools are used to extract glacier outlines, derive of a digital elevation model, and compute area versus elevation distribution functions from data acquired by thedoi:10.1109/tgrs.2004.834636 fatcat:mvb7qedxnjgshkgrb73wrjtale
