摘要
文中基于Arc GIS软件平台,通过对DEM进行分析处理,实现分水线和合水线数据的提取,并结合已有正射影像等相关地理信息数据构建三维立体模型,实现区域地形地貌地物的三维可视化、可量测和可漫游操作,可用于进行泥石流灾害预分析、道路选线、勘界选址、地质监控、建设规划等方面。
In the paper, extractions of water collection lines and water divide lines data were achieved, based on ArcGIS software platform, through the analysis of DEM. Combining with existing ortho images and other related geo- graphic information data to build a three -dimensional model, 3D visualization, measurement and roaming operation of the regional topography feature were realized, and could be used for the debris flow disaster pre - analysis, road line selection and demarcation location, geological monitoring, construction, planning and other aspects.
