Summary
UNEP/GRID Documentation Summary for Data Set:
Distribution of 10 Endangered Animal Species of Africa
The ten maps of Endangered Animal Species distributions in Africa
were provided by the International Union for the Conservation of
Nature and Natural Resources (IUCN) - World Conservation Monitoring
Center (WCMC) to UNEP/GRID-Geneva for digitization into ... computer
form in 1986. The ten maps were digitized in ARC/INFO on a Prime
computer system, and subsequently transferred to a Perkin-Elmer
machine and rasterized to a two-minute cell size in the ELAS
software format. Today, the same data files reside at GRID on an
IBM mainframe computer, but they have never been updated. Each of
the ten data files shows the distribution (i.e., presence/absence)
of a particular animal species for the whole of Africa. The Latin
and common names of the ten species digitized are shown below.
Species Name Common Name Location

Panthera Leo African Lion (?)
Balaeniceps Rex Shoebill C. & E. Africa K

The source of these data files is the Protected Areas Data Unit (PADU)
of WCMC-IUCN in Cambridge, U.K. as digitized by GRID-Geneva. There is
no reference available for the original maps themselves, although one
may refer to the 1986 IUCN Red List of Threatened Species, prepared by
the IUCN Conservation Monitoring Center in a volume of 105 pages.
Each of the ten Endangered Animal Species distribution data files has
a
spatial resolution of two minutes (120 seconds) of latitude/longitude,
or approximately 3.7 kilometers. The data files consist of 2191 rows
(lines, records) by 2161 columns (elements, pixels, samples) each.
Their common origin (upper-left or northwest corner) is 38 degrees,
0 minutes and 45 seconds North latitude (38 d 00' 45" N), and -20
degrees, 1 minutes and 15 seconds West longitude (-20 d 01' 15" W);
and they extend to -35 degrees, 1 minutes and 15 seconds South
latitude (-35 d 01' 15" S), and 52 degrees, 0 minutes and 45 seconds
East longitude (52 d 00' 45" E) at their terminal point (lower-right
or southeast corner). Each data file comprises 4.74 Megabytes.
* - Status according to the 1986 IUCN Red List of Threatened Animals;
where "Ex" = Extinct; "E" = Endangered; "V" = Vulnerable; "R" =
Rare; "I" = Indeterminate; "K" = Insufficiently known; "T" =
Threatened and "CT" = Commercially threatened.
