Africa Major Human Settlements and Landuse, 1984

The Africa Human Settlements and Landuse data sets form 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. This data set was developed in
collaboration with the United Nations Environment Program (UNEP),
Kenya.

The base maps used were the UNESCO/FAO Soil Map of the world (1977) in
Miller Oblated Stereographic projection, the DMA Global Navigation and
Planning charts for Africa (various dates: 1976-1982) and the
Rand-McNally, New International Atlas (1982). All sources were
re-registered to the basemap by comparing known features on the base
map those of 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
using an unpublished algorithm of the US Geological Survey and ESRI to
create coverages for one-degree graticules. The Population Centers
were selected based upon their inclusion in the list of major cities
and populated areas in the Rand McNally New International Atlas.
