Global HydroBASINS

HydroBASINS is a global river and lake catchment layer derived from HydroSHEDS and the global lakes and wetlands database (GLWD). HydroBASINS provides the most accurate hydrographic information for river and lake catchments at the global scale in a consistent format. It offers a suite of geo-referenced data sets (vector and raster) at various scales, including river networks, river and lake catchment boundaries, drainage directions, and flow accumulations. HydroBASINS is based on high-resolution elevation data obtained during a Space Shuttle flight for NASA's Shuttle Radar Topography Mission (SRTM).

River and lake sub-catchments within HydroBASINS will form the spatial unit for mapping species distributions and associated environmental parameters in the BioFresh analyses. It is hoped that HydroBASINS will be widely adopted by other organisations as the standard base layer for this type of data.
