HYDRO-1 Kilometer Flow Drainage Network

H1k_FLOW: River "flow accumulation" network from the HYDRO1k for Africa, reprojected to decimal degrees from Lambert Azimuthal Equal Area base, the only "networked" AWRD River layer. HYDRO1k is the Global Hydrological 1 kilometre database of hydrologically filled DEMs, "river" flow, and watershed networks based on the GTopo30. The H1K_FLOW shapefile data layer is comprised of 15478 derivative raster watershed and flow network features derived based on 4 000 cell data originally from HYDRO1k. The layer provides nominal analytical/mapping at 1:2 000 000. Data processing is complete globally, this is an African subset.
