Data lineage:
Based on the "FAO Land and Water Division Major hydrological basins of the world", the dataset was produced by merging the existing continental datasets and updating coding systems. Original data was obtained by delineating drainage basin boundaries from hydrologically corrected elevation data (WWF HydroSHEDS and Hydro1K).
