【 摘 要 】

For instance objects based on the HeiHe river basin and its water system, based on the space shuttle radar topography production of 90m high-resolution SRTM-DEM data, using the Hydrology ArcGIS10.2 hydrological analysis module of HeiHe river basin drainage network extraction and related analysis, verified the SRTM-DEM data application in hydrological analysis, also objectively shows the SRTM-DEM data the prospect of application in hydrological aspects is very objective.
