HydroSHEDS (Hydrological data and maps based on SHuttle Elevation Derivatives at multiple Scales) provides hydrographic information in a consistent and comprehensive format for regional and global-scale applications. HydroSHEDS offers a suite of geo-referenced data sets (vector and raster), including stream networks, watershed boundaries, drainage directions, and ancillary data layers such as flow accumulations, distances, and river topology information. HydroSHEDS is derived from elevation data of the Shuttle Radar Topography Mission (SRTM) at 3 arc-second resolution. Available HydroSHEDS resolutions range from 3 arc-second (approx. 90 meters at the equator) to 5 minute (approx. 10 km at the equator) with seamless near-global extent.
The goal of developing HydroSHEDS was to generate key data layers to support regional and global watershed analyses, hydrological modeling, and freshwater conservation planning at a quality, resolution and extent that had previously been unachievable.

SRTM Data Products
HydroSHEDS is derived from elevation data of the Shuttle Radar Topography Mission (SRTM) at 3 arc-second resolution. The original SRTM data have been hydrologically conditioned using a sequence of automated procedures. Existing methods of data improvement and newly developed algorithms have been applied, including void-filling, filtering, stream burning, and upscaling techniques. Manual corrections were made where necessary. For more details please refer to the HydroSHEDS Technical Documentation.

The HydroSHEDS package provides a suite of various raster and vector data sets, covering many of the common derivative products used in hydrological analyses. The data is prepared in seamless mode and is provided as global or continental maps, or in five-degree by five-degree tile coverage. All elevations are in meters referenced to the WGS84 EGM96 geoid. For more attribute information please see the HydroSHEDS Technical Documentation.
At this time, HydroSHEDS provides only selected core data sets at 3 arc-second and 15 arc-second resolutions, including drainage directions and elevation surfaces. A vectorized stream network is available at 15 arc-second resolution only. Future data developments are scheduled to include basins; flow accumulations; slope; aspect; wetness index; stream orders; flow distances up- and downstream; as well as seamless global products at 30 arc-second and 5 minute resolution.
