Hydrography90m

High-resolution global hydrographic dataset. 90 m stream network with stream segments as vectors.

A stream network extracted from MERIT Hydro with a minimum upstream area of 0.05 km², so it holds far more headwater streams than most global networks. Stream segments come as GeoPackage lines in 20° × 20° tiles, with stream order, slope, distance and sub-catchment rasters alongside.
