Curvatures are fundamental terrain attributes, widely used in land surface analysis. The standard approach is to define curvatures for regular grid digital elevation models on the basis of a sliding window algorithm emphasizing height variation in a $3\times 3$ neighborhood of each sample point. In the talk I will discuss the challenge of defining curvatures directly for triangulated terrains by using suitable algorithms and I will briefly compare the two approaches.
