SRTM River-Surface Water Bodies

ISO19115/19139 XML

Identification info
Title SRTM River-Surface Water Bodies
Date 27-11-2006
Date type creation
Edition Second
Presentation form mapDigital
Abstract Seamless and robust derivative of SWB, Double-Lined River, and Inshore Island Features from SRTM-SWBD data tiles. The SWBD_PY shapefile data layer is comprised of 38840 derivative vector surface water bodies features derived based on 1:100 000 data originally from SRTM-SWBD. The layer provides nominal analytical/mapping at 1:125 000. Data processing 60% complete globally, with African and Arabian subsets 100% complete.

Acronyms and Abbreviations:
SWB or SWBD - Surface Water Body;
SRTM - Shuttle Radar Topography Mission.
Purpose Highest resolution water body and coastal mask of Africa.

The primary AWRD interface, tool-sets and data integral to the function of the AWRD are distributed in two DVD's accompanying CIFA No. 33, Part 2, and are also available for download from FAO's GeoNetwork and GISFish GIS portals.

Statement Data were processed and consolidated from 1,376 NASA-SWBD tiled ESRI 3d-Shapefile datasets download from ftp://e0srp01u.ecs.nasa.gov/srtm/version2/SWBD/SWBDeast or SWBDwest into a single and topologically consistent ESRI coverage format. Polygonal data were deconstructed to lines and tile seams removed using ArcInfo; double precision coordinate references and tolerances of 0.000001 were used for all transitive processing; coastline/offshore island polygonal topology 1st reestablished. All universally bound BA040-Water Except Inland removed to correctly delineate oceanic shorelines. BH080-SWB and BH140-Dbl-lnd River polygon topology next reestablished with all internally bound non-source polygons encoded as islands. Non-universally bound BA040 polys added back and final Arc/Pnt/Poly topology established with: Poly2Ln and Poly2Pnt coding attribution. Original 3d elevation attribute added back to BH080 as single and BH140 as range of elevation values.
