mm on the map generates a planimetric error of 10 m on the
DTM which has also 10m vertical resolutions, respectively, and
covers an area of about 3800 km2.
Satellite data converts to Earth coordinate system (e.g.
Universal Transverse Mercator System) from the spectral
response values of the original image by using ground control
points (GCP). GCP were generated from mostly topographic
maps. According Welch and Usery (1984) maximum error must
be less than half of pixel size in transformation of satellite
(maximum error must be less than «15m. for Landsat ETM).
For this purpose more than 40 GCP were selected from
mountain.
Image Processing (IP) software (ERDAS) were used to
manipulate this data set. Image Drape was used to generate
perspective view of mountain (Figure 3).

4. CONCLUSION
A DTM of Mt. Erciyes stratovolcano has been presented. Image
Processing techniques used to construct digital terrain model of
Mt. Erciyes. Geomorphologic map of study area produced by
using remote sensing technologies, satellite data and DTM
(Figure 4).

Morphological units are described by image processing
systems. Topographic analysis from maps and field studies
improved by measure and analysis forms of terrain using by
satellite data and DTM (Figure 2). Additionally topographic
analysis from field observation are added map. Obviously seen
that, this techniques opens new dimension on volcanology,
mountain geomorphology and cartography. The analysis of
slope distribution and aspect map derived by the DTM.
