A digital elevation model (DEM) can be described as a three-dimensional representation of a terrain surface consisting of X, Y, Z coordinates stored in digital form, excluding any other non-terrain feature.

Using elevation models, features such as scarps, steep slope units, lobed accumulation zones, and uneven topography can be enhanced to allow delineation and classification of landslides.
