The E00 file is in Arc/info format and should be imported with the
Arc/Info command Import cover In-Filename Out-Filename. This soil
dataset is part of the Lake Chad Database that covers parts of 7
countries: Cameroon, Chad, Niger, Nigeria, Central African Republic
(CAR), Libya and Sudan and is based on the UNEP/FAO/ESRI (Africa)
Database. It was developed by UNEP/GRID, on behalf of the UNEP/Fresh
Water Unit for the Lake Chad Commission on Sustainable Development.
This datasets are based on the 1977 FAO/UNESCO Soil Map of the World
(Topographic) at a scale of 1:5000000 in Miller Oblated Stereographic
projection and the DMA Navigation and Planning Charts (various dates:
1976-1982) and the National Geographic Atlas of the World (1975).

File SOILNEW represents FOA soil classes
File PEDOLOGY shows Pedogenic processes, regimes, indicator and severity class.
File TXTSLP having items VEG and TYPE should represent texture and slope
classes?
File SOILS.E00 has only tics and study extent (mape) only.
