Abstract

Error models of slope and aspect of a terrain are presented in this paper. Such data are often extracted from a GIS which may contain information from digital maps and remote sensing images. Although the sources of these data are usually of diverse resolution, all of them are usually re-sampled to refer to the same resolution. In this paper we shall examine the error which is associated with such data because of subsampling. The error distributions will be modelled empirically.
