Africa Data Sampler (ADS): Digital Data Sets for Africa Available from the World Resources Institute (WRI)

The ADS is an integration of map data from several GIS databases. Roads, rivers, settlements, topography, and other essential base map features were extracted from the Arc/Info version of the Digital Chart of the World (ESRI, Redlands, CA).

Data representing forests, wetlands, and protected areas from the Biodiversity Map Library (World Conservation Monitoring Center, Cambridge, UK), and sub-national boundaries and population estimates from the National Center for Geographic Information and Analysis (Santa Barbara, CA) were integrated with the DCW data sets. Over twenty layers of data are available for most countries. The ADS comprises a CD-ROM and User's Guide.
