Topographic parameters extracted from digital elevation model (DEM), provide valuable information about characteristics of the earth surface. These parameters are used in quantitative geomorphology with regard to terrain analysis. By using these topographic parameters along with Geographic Information Systems (GIS) and computer technology, feasible classification, mapping and geometric description of geomorphologic landviews would be accessible. In this survey part of northwest landviews of Shiraz were classified by using 4 topographic parameters (height, slope, profile curvature and planimetric curvature) extracted from DEM in GIS, and via interative self-organizing data analysis technique (ISODAT). The results of classification show five classes (and 7 landveiws) including :
1-relatively high mountains, 2-alluvial fans & high foothills, 3-low hills, 4-plains & flat surfaces and 5- low mountains & high hills. These results were compared with Shiraz land type's maps.According to The pertaining analysis, the application of topographic parameters & ISODAT method would be considered as a fairly efficient and suitable technique regarding to landviews classification. It is argued that the method is easy, low cost, fast and relatively precise and well available in most softwares of GISs.
