| Abstract | An automated morphometry-based approach to outline the debris-covered glaciers of the Mt. Everest Area (Nepalese Himalaya) based on ASTER data is presented. In order to obtain a satisfying ASTER DEM of this extreme topography "unnaturally" peaks were automatically identified and eliminated, and "holes" were filled with elevation data from topographic maps. The developed morphometric glacier-mapping method includes altitude, slope, plane- and profile curvature as well as thermal information. The result clearly indicates the area of the debris- covered glaciers. Problems occur mainly in the distal parts of the glacier tongues where the glacier ice is inactive and thick debris- covers show no signs of movement. Here, the resolution of the ASTER DEM is not sufficient. However, the results show the proof of this concept, and available multitemporal DEMs of higher resolutions in near future will still improve them. |
