Data details

UID 927
Name Multi-Error-Removed Improved-Terrain Hydrography (MERIT Hydro)
Description The Multi-Error-Removed Improved-Terrain Hydrography is a global high-resolution hydrography dataset derived from the MERIT DEM, providing consistent layers of river flow direction, river networks, upstream drainage area, river width, and hydrologically corrected elevation (HAND). It is designed for global hydrological and flood modelling applications and improves river network representation by correcting DEM errors and integrating multiple water body datasets.
