Landform Classification in R

Jasiewicz and Stepinkski (2013) provided a novel method for classification and mapping of landform elements from a digital elevation model (DEM) based on the principle of pattern recognition rather than differential geometry. At the core of the method is the concept of a geomorphon (geomorphologic phonotypes) — a simple ternary pattern that serves as an archetype of a particular terrain morphology. From a total of 498 possible combinations a set of ten distinct patterns is formed (see figure 1).
