HydroATLAS (beta version)


HydroATLAS represents a global compendium of hydro-environmental sub-basin and river reach characteristics at 15 arc-second resolution.

The goal of HydroATLAS is to provide a broad user community with a standardized compendium of hydro-environmental attribute information for all watersheds and rivers of the world at high spatial resolution. Version 0.1 of HydroATLAS offers a set of 70 attributes organized in seven categories: hydrology; physiography; climate; land cover; geology; soils; and demographics. HydroATLAS derives the hydro-environmental attributes by reformatting original data from well-established global digital maps. The attributes are then linked to hierarchically nested sub-basins at multiple scales, as well as to individual river reaches, both extracted from the global HydroSHEDS database.
