HydroSHEDS is a comprehensive initiative launched in 2006 by the World Wildlife Fund US, aimed at enhancing hydro-ecological research and conservation globally. The project offers free, seamless hydrographic data products, including catchment boundaries, river networks, and lakes. The upcoming HydroSHEDS v2 promises to revolutionize these offerings with improved hydrographic details sourced from the advanced 12m TanDEM-X dataset, set to launch in early 2024.

HydroSHEDS provides data categorized into core, secondary, and associated products. Core products include digital elevation data and flow direction grids, while secondary products expand on this data to create standardized global maps enriched with hydro-environmental attributes. Associated products enhance the core data with additional hydrographic datasets.

Although HydroSHEDS aims for high-quality global coverage, its accuracy may not match localized, fine-resolution maps. Instead, it focuses on providing consistent and seamless data suitable for regional and global hydro-environmental modeling and freshwater conservation efforts. With its comprehensive suite of products, HydroSHEDS is a vital resource for researchers and environmentalists working to protect our waterways.
