Module Fuzzy Landform Element Classification

Algorithm for derivation of form elements according to slope, maximum curvature, minimum curvature, profile curvature, tangential curvature, based on a linear semantic import model for slope and curvature and a fuzzy classification Based on the AML script 'felementf' by Jochen Schmidt, Landcare Research.
