What is Terrain Ruggedness Index Methods about?

This document discusses two common methods for categorizing terrain ruggedness: the relief method and the surface area method. The relief method calculates the difference between focal maximum and minimum elevation values. The surface area method involves: 1) dividing a slope map by 100, 2) converting slopes to angles using arctangent, and 3) calculating a surface area factor using cosine, which provides an inverse ruggedness index value. Both methods can serve as indices for ruggedness when comparing terra
