摘要
数字高程模型DEM在各行业和领域已经得到了广泛的应用。本文构建了区域DEM,并借助ArcGIS软件对其进行了坡面姿态地形分析,通过坡度和坡向提取与分析,得到了区域的坡度组成和平均坡度,并实现了区域坡面姿态的制图应用。
DEM has been widely used in various industries and fields. This paper constructed the DEM of basin and analyzed the slope stance of topography with ArcGIS, and then obtained the composition and average slope of the basin through the extraction and analysis of the slope, and finally realized the drafting application of the basin＇s slope stance.
