Study on the Extraction of Urban Water Systen and River Basin Based on Multiple-source DEM Fusion

There is difference on extraction of urban water system and river basin because different data source of DEM has a different elevation error. In order to reduce the impact of single DEM error, this paper proposes an effective way to improve the DEM accuracy by fusing the multi-source DEM and reducin...
