In this paper we briefly review a selection of measures of surface roughness, with specific application to grid based digital elevation models (DEMs). A selection were assessed for the behaviour of roughness at different spatial scales and dataset resolutions using moving-window and raster algebra steps to a test area in the Midland Valley, Scotland.
