摘要
坡度是最基本的地形因子之一。本文介绍了基于DEM的坡度计算方法,对坡度分级统计中的误差来源分类进行分析,并实验分析其DEM精度,以及各误差因素对坡度统计计算的影响。
Slope is one of the most frequently used terrain parameters in Geo - science model. This paper introduces some calculating methods about slope based on Digital Elevation Model （ DEM）, and discusses the source of error. It also studies the accuracy of DEM and points out the effects of different error factor on slope statistics and calculation.
