As the remote sensing data are images obtained multispectrally, they very well display the morphological structure of topographic features. Looking at this morphological structure, assessment of the structural features among the ground formations can be made. Since the remote sensing data are two-dimensional, their use falls inadequate in many studies where the topographic features are of particular importance. However use of three-dimensional data obtained by combining the different band combinations of satellite ima;es with digital elevation model made by using various data groups brought about a new dimension to topographic studies. In this study, topographic maps of 1 / 25 000 scale have been digitized to form a digital elevation model. From the obtained digital elevation model, slope groupings were made to prepare slope map. Topographic map which had been previously analyzed according to elevations was merged with this slope map to determine in computer media the flat terrains in the area of study. As the remote sensing data which are used by merging with digital elevation model display the morphological structure of the earth's surface, geomorphological surfaces can be defined on this model. This has brought great facilities to the studies of defining the geomorphological features in very large areas.
