The administrative units dataset is part of the UNEP/FAO/ESRI
Database project that covers the entire world but focuses here on
Africa. The maps were prepared by Environmental Systems Research
Institute (ESRI), USA. Most data for the database were provided by the
Soil Resources, Management and Conservation Service Land and Water
Development Division of the Food and Agriculture Organization (FAO),
Italy. The database was developed by the United Nations Environment
Program (UNEP as part of a project initiated by UNEP.

The base maps used were the FAO/UNESCO Soil Map of the World
(1977) in Miller Oblated Stereographic projection, FAO Maps and
Statistical Data by Administrative Unit (1983), and the Rand-McNally
New International Atlas (1982). All sources were re-registered to the
basemap by comparing known features on the basemap and the source
maps. The digitizing was done with a spatial resolution of 0.002
inches. The maps were then transformed from inch coordinates to
latitude/longitude degrees. The transformation was done by an
unpublished algorithm (by US Geological Survey and ESRI) to create
coverage"'"s for one-degree graticules.
