| Abstract: | Based on DEM data,according to the principle and process of the automatic extraction of water,the article builds the model of the stream automatic extraction used ArcGIS Model Builder.It accomplishes the depressions filling,the calculation of flow direction and flow accumulation,and the generation of vector river-net,so that it can complete extraction of natural stream. |
