Date type creation
Edition Second
Presentation form mapDigital
Abstract 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.

HYDRO1k - HYDRO1k - Global Hydrological 1 kilometre database of hydrologically filled DEMs;
AWRD - FAO-FIMA?s African Water Resources Database & Tools Interface;
DEM - Digital Elevation Model.
Purpose A six level watershed model and derivative flow routes.

Supplemental Information This map is part of two publications entitled:
"Jenness, J.; Dooley, J.; Aguilar-Manjarrez, J.; Riva, C. African Water Resource Database. GIS-based tools for inland aquatic resource management. 1. Concepts and application case studies CIFA Technical Paper. No.33, Part 1. Rome, FAO. 2007. 167p. "

Statement Projected into decimal degrees and building on the Hydro1k baseline, the encoding of this WS Model was extensively modified to allow for the visualization of megabasin, river system and individual watershed related flow regimes via the AWRD interface. All original extant attributes have been maintained, but additional attributes related to flow orientation and summary statistical attributes have been added.
