Abstract

In this paper, the authors have analyzed the effects of different precisions on the watershed terrain features derived from DEMs and quantitatively studied the error of slope. As an example of Mangniuhe watershed in Miyun reservoir, this paper analyzed the terrain features derived from DEMs with different precisions, and made error control on the value of slope derived from different precisions of DEM. The curve estimation regression method was used to formulate the equations of slope losses and fitting. Tests show that this method can better control the error, thus deserving wide application.
