HydroATLAS version 1.0 (coming in November 2019)


HydroATLAS represents a global compendium of hydro-environmental sub-basin and river reach characteristics 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 organized in seven categories: hydrology; physiography; climate; land cover & use; soils & geology; and anthropogenic influences. In its first version, HydroATLAS will offer over 50 hydro-environmental variables, partitioned into more than 250 individual attributes.
