RIVER NETWORK

High-resolution raster hydrography maps are a fundamental data source for many geoscience applications. Here we introduce MERIT Hydro, a new global flow direction map at 3 arc-second resolution (~90 m at the equator) derived from the latest elevation data (MERIT DEM) and water body dat ...

RIVER NETWORK AT 30s RESOLUTION HydroSHEDS is derived primarily from elevation data of the Shuttle Radar Topography Mission (SRTM) at 3 arc-second resolution. SRTM data were used in different versions and processing stages, including SRTM-3 unfinished data; DTED-1 finished data; and CG ...
