Abstract
Two kinds of terrain representation error which extracted from the Digital Elevation Model (DEM) with different spatial resolutions and different convolution resolutions are studied respectively, and the comparison between them are made. An average slope error estimation model validated suitable for Beijing with a relative error less than 20% is proposed, which can simulate quantitatively the variation of the average slope error according to the DEM resolution. The contour data with the scale of 1:10000 is treated as data source in this paper.
