Lake Chad Datasets, Africa
Listed in NASA Earthdata CMR
The Lake Chad Dataset which is a detailed case study of the UNEP/FAO/ESRI Family was developed by UNEP/GRID, on behalf of the UNEP/Fresh Water Unit for the Lake Chad Commission on Sustainable Development.
Description
Lake Chad Dataset covers parts of 7 countries: Cameroon, Chad, Nigeria and Niger, Sudan, Central African Republic and Libya and is a clip (regional version) of Africa Outline Dataset (NBI01). The base maps used for the continental version were the FAO/UNESCO Soil Map of the World (1977) in Miller Oblated Stereographic projection, FAO Maps and Statistical Data by Administrative Unit and the Rand-McNally New International Atlas (1982) to clarify unit boundaries.
Files: ADMIN.E00 Code: 115001-001 BASE.E00 115002-001 COUNTRIES.E00 115003-001 Vector Members The E00 files are in Arc/Info Export format and should be imported with the Arc/Info command Import cover In-Filename Out-Filename. The ADMIN polygon dataset showing administrative areas for 7 countries around Lake Chad. The BASE is a polygon Dataset showing the countries with inland water bodies.
