ABSTRACT: 
Satellite data and Digital Terrain Models (DTM), complemented by field structural analysis permit a new understanding of relations 
between tectonics and volcanism. A DTM of Mt. Erciyes (3917 m.) is presented; it has 10m vertical and horizontal resolutions, 
respectively, and covers an area of about 3800 km2. Landsat ETM data were used to identification of morphological features of 
Erciyes Stratovolcano Complex (ESVC). This observations and analysis are able to improved by measure, monitor and analysis 
forms of terrain using by satellite and DTM data. Using both DTM and remote sensing together open new dimension on 
earthsciences and investigation morphological features of mountains and volcanoes. Perspective view of Mt. Erciyes allowed both 
recognition and location of the main morphological and volcanotectonic features of the valcano. A slope, aspect maps have been 
generated from the DTM. Geomorphological features of Mt. Erciyes including glaciations of ESVC and lineaments of surroundings 
area are discussed by remote sensing technologies and DTM both indepentedly and together in this paper 
1. INTRODUCTION 2. STUDY AREA 
Globally significant interactions between surfce processes, Central Anatolia Volcanism has developed since the late

mountain areas (Bishop et al, 2003). Aspecially, volcanic et al., 1988). This mechanism has been considered to be related

features resulting from complex interplay between regional and 
local tectonic regimes and eruptive dynamic and rhelogical 
characteristics of the emitted products. Revevant morphological

In this paper, morphological features of the highest and the 
largest stratovolcano of Central Anatolia is analysed and 
described by DTM and Satelite data (Landsat ETM). Erciyes 
Mountain is located in the north-eastern part of the we 
Coppadocian Volcanic Plateau. Erciyes Stratovolcano Complex 
(ESVC) is characterized by four valleys and one ridge that 
contain a glacier and Late Quaternary glacial deposits on its 
flanks (Sarikaya, et al. 2003a). Additionally glaciations of WN 
ESVC is investigated in this paper. 
Analysis of the topography of mountain areas, however, is 
increasingly being used to study surface processes due to the 
more availability of DTM from both remote sensing and 
digitizing topographic maps (Bishop et al., 2003).
