Abstract: Recent developments in computer programs and information technology have resulted in an increasinginterest in the use of DEMs in tectonic studies. Geographic Information Systems (GIS) and Digital ElevationModels(DEM) have been extensively used in morphological and tectonic studies and give good results, especiallyin revealing the morpho-tectonic features of a geologically unknown region. The study reported here comprisesthe extraction and analysis of landforms using the geographic information system analysis of a region where strikeslip faulting has a dominant role in the formation of landforms. The morpho-tectonic characteristics of the area,which stretchesfrom a point East of Gerede to İsmetpaşa on the NorthAnatolian Fault Zone (NAFZ), were studiedusing GIS and digital mapping techniques. Landsat ETM+ and shaded relief images were also used in order toperform lineament analysis.Typical landforms associated with a strike slip faulting regime, like offsetstreams,sagponds etc. were recognized by DEM and the results were supported with field observations. The advantages anddrawbacks ofthe use of GIS in tectonomorphologic studies are discussed asthe result ofthis work.
