The two notions of flatness and roughness refer to local properties of the profiles and of the surfaces. They are defined in two- and three-dimensional spaces. Flatness is the ratio of the measure of the surface divided by its projection, and roughness the average of the square of the mean curvature of the surface per unit area.
