RWDB2 Surface Water Bodies for Africa

ISO19115/19139 XML

Identification info
Title RWDB2 Surface Water Bodies for Africa
Date 2006-05-05
Date type creation
Edition Second
Presentation form mapDigital
Abstract This dataset derives from the RWDB_SWB-PY shapefile data layer which covers the entire globe and is comprised of 8750 derivative vector framework library features derived based on 1:3,000,000 data originally from RWDBII. The original dataset is an enhanced SWB polygonal derivative based on 4 separate RWDB2 Library layers. The layer provides nominal analytical/mapping at 1:3,000,000.
Acronyms and Abbreviations:
RWDB2 or RWDB II- Relational World Database II
SWB - Surface Water Body
Purpose 14 plus data topical layers; Appendix 1.

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 CIAMAP in Shape Files version 1.1 (formerly RWDBII), this is the first distribution/update of the original 1982 WDBII. Data derived from source library following Dbl-Prsn/Tol0.00001 and a number of steps and cross-checks, including but not limited to: 1) Polygons: 1st built from linear features where available then cleaned/dissolved using unique attributes and then compared against source material; 2) Linear features: processed as lines and cleaned/dissolved on unique combination of specific attribute to maintain encoding. Relevant linear or polygonal outlines from other library layers then added to topologically reduce gaps, e.g. rivers/swb outlines--where necessary data from VMap0 Ed5 may have been used to further reduce gross errors as in state/pro add Lns for: SWBs, Dbl-lined Rivers, Land/Sea Ice build Poly, add Lns for Inshore Islands, 1st-order Subnational, Law of the Sea boundaries build poly and establish National; add remaining linear features: rivers, roads, etc.; add point features, e.g. Po
