GRIT Global River Topology

A bifurcating river hydrography (v1.0). 30 m river network with channels that split and rejoin.

A river network built on FABDEM and Landsat-derived river masks that keeps bifurcations, so deltas, braided rivers and canals are represented as multi-threaded channels. Reaches, segments and their catchments come in seven regional files, plus a simplified global network.
