Abstract
Digital elevation models (DEMs) derived from satellite data are increasingly
used for geomorphologic and glacial analysis. Recently, digital elevation data
from the Space Shuttle Radar Topography Mapping Mission (SRTM) in ~90m
grid resolution is available for many parts of the earth. The Advanced
Spaceborne Thermal Emission and Reflection Radiometer (ASTER) produces
simultaneous stereo-pair data allowing the generation of detailed DEMs with a
resolution of 15 to 30m. ASTER-DEMs have been generated for selected areas
in Sailiskiy and Kungey Alatau. The analyses were verified with results from
field work. Clouds represent one of the main problems in ASTER DEM
generation; such cloud-covered areas were marked, clipped and filled with
SRTM data. The accuracy of the DEM was evaluated by comparison with a
DEM derived from contour maps. With the help of geomorphic analyses and
satellite images a map of the glaciers and rockglaciers could be produced. Using
the Software ArcGIS the area, geomorphic features and solar radiation
conditions of selected glaciers and rockglaciers was calculated. The results show
that the DEM is of good acuracy and is useful for an interpretation of the macro-
and mesorelief.
