Short summary
Short summary
Streams and rivers drive several processes in hydrology, geomorphology, geography, and ecology. A hydrographic network that accurately delineates streams and rivers, along with their topographic and topological properties, is needed for environmental applications. Using the MERIT Hydro Digital Elevation Model at 90 m resolution, we derived a globally seamless, standardised hydrographic network: Hydrography90m. The validation demonstrates improved accuracy compared to other datasets.

Short summary
To support the conservation of freshwater ecosystems and biodiversity, standardized and high-resolution information is key. Environment90m is a new dataset, which aggregates 104 environmental variables across the 726 million sub-catchments of the Hydrography90m river network. It includes present and future climate, land cover, soils, topography, hydrographic and streamflow information. Environment90m provides an array of opportunities for research and applications in freshwater science.
To support the conservation of freshwater ecosystems and biodiversity, standardized and...
