| 摘 要： | 利用ArcGIS软件中的水文分析工具,在DEM表面之上再现水流的流动过程,最终完成水文分析过程。列举实例对ArcGIS与DEM数据进行提取河网、河网分级、生成流域边界等水文分析工作,对形成的水文模型与真实地形进行比较和分析误差。实验结果表明模拟出的河网与水利部门提供的地形资料基本相符,后续研究可利用更高质量的DEM影像进行提取。

| Abstract: | Using the hydrological analysis tools of the ArcGIS software,the article is based on the surface in the DEM to represent the flow process of water and at last complete the hydrological analysis.Cited examples of extracting data from ArcGIS and DEM river network,river classification,watershed boundaries,hydrologic analysis generated work on the formation of the hydrological model compared with the real topography and analysis of errors.Simulation results show that out of the river and the water sector to provide basic information on the topography of consistent follow-up of higher quality can be used to extract DEM image. |
