Abstract

By combination of digital elevation models (DEM) with digital geological maps within GIS environment, it is possible to detect the topographic analysis in relation to the site analysis of the study area. This technique has been S demonstrated on Jimeta metropolitan DEM map. From a topographic point of view, large relief defines mountains essentially. Thus, digital elevation models (DEM) usually form the base data for any mountain geoinformation system and any spatial model. The DEM is the digital representation of continuous changes of relief within space (Burrough 1986, 39). Information generated From the DEM is of critical importance within many GIS applications and is used to produce contours and many other types of information including; indivisibility, slope, profiles, watersheds, aspect and the concavity and convexity of a surface. Shuttle radar topographic mission (SRTM) help in obtaining digital elevation models on a near global scale.
