Welcome to the HydroSHEDS website!
This is the official and only maintained website providing HydroSHEDS data. You currently can also find HydroSHEDS at the USGS mirror site (see Links above); but note that the USGS site is no longer updated.
NEW products: Global River Classification GloRiC and HydroATLAS
We would like to announce a new dataset - the Global River Classification GloRiC. For information and data go <here>.
Also, you now can find a first glimpse of the forthcoming hydro-environmental attribute database HydroATLAS <here>.
Hydrological data and maps based on SHuttle Elevation Derivatives at multiple Scales
HydroSHEDS is a mapping product that provides hydrographic information for regional and global-scale applications in a consistent format. It offers a suite of geo-referenced data sets (vector & raster) at various scales, including river networks, watershed boundaries, drainage directions, and flow accumulations. HydroSHEDS is based on high-resolution elevation data obtained during a Space Shuttle flight for NASA's Shuttle Radar Topography Mission (SRTM).
