Algorithms for evaluating digital terrain models (DEMs) and elevation moments such as slope, aspect, relief, and curvature are discussed. Significant new applications based on the elaboration and display of such data are presented. The results show that the processed data can be used for environmental protection and to identify topography-dependent natural-disaster hazards.
