The Africa Map project, currently in beta, is an online map and data viewer created by Harvard University. The map combines data sets of numerous categories from a wide variety of sources, allowing thematic maps to be viewed and explored. The purposes of the project, according to the project web site:
Interact with the best available public data for Africa
See the whole of Africa yet also zoom in to particular places
Accumulate both contemporary and historical data supplied by researchers and make it permanently accessible online
Work collaboratively across disciplines and organizations with spatial information about Africa in an online environment
Just read a great article from Grassroots Mapping about a public participation GIS project recently conducted for the Cantagallos community in Lima, Peru. To help the community bolster their land claims to the territory they've settled, Grassroots Mapping led an aerial photography gathering mission using helium balloons and a camera. Since the Google Maps / Earth imagery for the region was a few years old and didn't show recent changes to the environment, the detailed up-to-date aerial photography provided a more accurate base map for future public participation mapping efforts!
