The quantitative analysis of the morphology of landforms. It uses general geomorphometric measures to capture the basic characteristics of landscapes, like slope, convexity, concavity, aspect, linearity, etc., and specific geomorphometry: the use of quantitative measures designed for analysis of specific landscape features. See Pike (2000) PPG 24, 1.

Geomorphometry uses input digital elevation models (DEMs, also known as digital land surface models); see Fisher et al. (2004) TIBG 29, 1. See Pike et al., eds in T. Hengl and H. Reuter, eds (2007) for a ‘brief guide’.
