Özet

Topography and slope, the most important factors that makes soil, can be identified easily by means of topographic maps. The most important factors regarding this issue are the scale and quality of cartographic material. In this study; the accuracy of slope maps provided with the use of the different scale topographic maps, one of these cartographic materials and probability of being soil boundary of those were compared. In consequence of digitizing of topographic maps through digital mapping techniques, different resolution DEM and slope maps were created. It was identified that the more resolution increased in slope maps acquired by geographic information system, the more the compatibility of slope maps with land decreased. The 2 m resolution slope map acquired by digitizing the 1:5000 scaled topographic map was determined to overlap with a high level of soil boundaries. The slope boundaries acquired from 1:25000 scaled map were found to be incompatible with land in lower levels.
