Abstract
A Digital Elevation Model (DEM) is a representation of geographic reality. The
elevations recorded within DEMs have been shown to contain errors pertaining to
sampling, measurement and interpolation (Fisher, 1998). Even a small amount of
elevation error can greatly affect derivative products (Holmes et al., 2000). This can
potentially have a significant impact on the application of DEMs in Geographical
Information Systems (GIS) where first and
second order derivatives are considered.
