TDX-Hydro and GEOGLOWS v2 Streams

NGA TanDEM-X hydrography and the GEOGLOWS river network. Global stream lines from the 12 m TanDEM-X elevation model.

TDX-Hydro is NGA's global stream network and basins derived from the TanDEM-X 12 m DEM, released in 2023 with about 16 million segments. GEOGLOWS v2 uses a modified subset of about 7 million rivers, published per vector processing unit (VPU) with catchments, lakes and outlets, and as a simplified global file.
