Topographic analysis has been widely used in the study of landscape evolution and surface process, and the researches in this field have become more and more quantitative. Local topographic relief, which is defined as the difference between local maximum elevation and local base level, is one of the key methods in topographic analysis. Based on a spatial analysis of the SRTM-DEM, this paper puts forward two methods for the acquisition of local topographic relief, i.e., Swath Profile and Threshold Value. The quantitative analysis of the erosion within a typical area of the Loess Plateau has been preliminarily realized by extending the Threshold Value method.
