Description :
Three different methods for calculating from a Digital Elevation Model (DEM) slope and aspect are discussed : the Four Contiguous Right Triangles, the Maximum Downward Gradient and the Bicubic Spline First Derivative; the resulting maps have been compared with each other at regional scale and for a small area with a slope map obtained by using classical techniques. The main goal of the comparison has been the choice of the best technique for the computation of the digital slope map of Italy.
