Journal of the Arkansas Academy of Science
Geographic Information Systems (GIS) offer a cost-effective way to analyze and inventory land and environmental resources. There are many attributes that can be displayed and analyzed in GIS. One of these attributes is slope, which can be calculated from a digital elevation model (DEM). Slope is an important factor in a variety of models used in land analysis as well as land use and management. There are several different mathematical computational algorithms used to calculate slope within a GIS. Eight different slope calculation methods were investigated in this study. These methods were used to calculate slope using 10-m, 30-m, and …
