Abstract
Incorporation of a physically-based general geomorphological theory directly into the segmentation algorithm is fundamental to physically-based land surface segmentation. Topographical steady state for morphostructural segmentations with five types of elementary forms defined by the principle of equilibrium provides a basis for definition of input variables. Examples of application introduce two new physically-based geomorphometric variables: Index of Steady State (ISS) quantifying the closeness of regions to a topographic steady state; and Index of Slope Disequilibrium (ISD), expressing percentage deviation from an equilibrium state of gravitational Potential Energy of Surface (PES) for mass flow.
