| 摘 要： | 对洼地积水问题进行了深入研究,从洼地处理和平地处理着手提出了新的解决思路,并在Visual Studio2005平台下,采用ArcGIS Engine组件开发了试验模块,并通过试验数据进行水系的提取。对比发现,算法提取的水系比ArcGIS填平预处理后提取的水系更加连续,且与原始DEM地形在三维显示状态下可以很好地拟合。

| Abstract: | We an approach present for water extraction.When handling with flow direction is inverse in depression,flow accumulation and potential energy accumulation are draw in,thus water can flow out.Based on Visual Studio 2005,we use ArcGIS Engine Components to develop testing modules.River system is extracted with testing data.After comparing with the results in ArcGIS,we find that the river system extracted can be more continuous and fit original DEM terrain in 3D display. |
