Abstract

Recent developments in computer programs and information technology have resulted in an increasing interest in the use of DEMs in tectonic studies. Geographic Information Systems (GIS) and Digital Elevation Models (DEM) have been extensively used in morphological and tectonic studies and give good results, especially in revealing the morpho-tectonic features of a geologically unknown region. The study reported here comprises the extraction and analysis of landforms using the geographic information system analysis of a region where strike slip faulting has a dominant role in the formation of landforms. The morpho-tectonic characteristics of the area, which stretches from a point East of Gerede to ismetpasa on the North Anatolian Fault Zone (NAFZ), were studied using GIS and digital mapping techniques. Landsat ETM+ and shaded relief images were also used in order to perform lineament analysis. Typical landforms associated with a strike slip faulting regime, like offset streams, sag ponds etc. were recognized by DEM and the results were supported with field observations. The advantages and drawbacks of the use of GIS in tectonomorphologic studies are discussed as the result of this work.
