摘　　要：本文探讨基于数字高程模型(Digital Elevation Model,简称DEM)的坡位图生成方法,主要包括DEM数据采集和预处理,生成山谷图、脊部图、平地图、上中下坡位图,整合生成坡位一张图等技术。使用该技术可以实现DEM数据向坡位图的转换,为地形分析和林业应用提供数据支持。In this paper,based on the Digital Elevation Model(DEM),a discussion was made on the slope bitmap generation method based on DEM,mainly including such techniques as DEM data acquisition and pre-processing,generation of valley map,ridge map,flat map,upper,middle and lower slope bitmaps,and integration and generation of a slope map.The techniques could be used to convert DEM data into a slope bitmap to provide data support for terrain analysis and forestry applications.
