根据地表径流模型原理,通过ArcGIS中的HydrologyTools模块进行D8算法提取流域水系,计算汇流累积量,并最终生成河网.结果表明:对1:1万DEM进行水系提取,最小水道集水面积阈值设定为50 000个栅格较合理;对于山地地形,基于1:1万DEM数据,利用ArcGIS Hydrology模块提取河网的方法,从提取的效率和结果的精度两方面看...

See Tools that do not create output datasets for more information and strategies to avoid undesired data changes. Vorsicht:A warning is raised if the input features are not in a projected coordinate system. This tool relies on linear distance units, and will create unexpected results in an un...
The data being operated on are maintained by Esri and used in the hydrology analysis service requests. A primary benefit of using these data sources is that a lot of the hard work has already been done, freeing you up to just work on performing analysis instead of having to worry about co...
Next you can identify and correct problems in the drainage network by using theUtility Networktools to create aGeometric Network. Once the Geometric Network is created you can set flags to perform various tasks including: identify loops, find path, and find connected. ...
