Abstract

The concept of a geomorphological signature is developed for classifying and mapping slope units with an automated procedure for analysing digital elevation and remote sensing data. Slope units are extracted from a digital elevation model (DEM) using a break of slope rule on downslope profiles. Each slope unit is an aggregated object of continuous pixels and is summarized with 5 suites of variables : shape, topography, topographic variability, spectral characteristics, and variability in spectral characteristics. A ten-class scheme is used to classify slope units for a study area in southwest Yukon, Canada
