HydroATLAS offers a global compendium of hydro-environmental sub-basin and river reach characteristics derived from existing global datasets at 15 arc-second resolution.

HydroATLAS is a comprehensive database gathering and presenting a wide range of hydro-environmental attributes from existing global datasets in a consistent and organized manner. HydroATLAS is divided in two datasets, BasinATLAS and RiverATLAS, which represent sub-basin delineations (polygons) and the river network (lines), respectively. HydroATLAS offers attributes grouped in seven categories: hydrology; physiography; climate; land cover & use; geology & soils; and anthropogenic influences. Version 1.0 of HydroATLAS includes a total of 56 hydro-environmental variables, partitioned into 281 individual attributes, that are derived from recent published sources.
