Mapping Wikipedia is a collaboration between TraceMedia and the Oxford Internet Institute. The map is generated from an archive of all the geo-located articles for a number of languages. For further information see the TraceMedia project page, and to learn more about the OII project that examines Wikipedia in the Middle East and North Africa, please visit here.
The map was created by TraceMedia using an Oxford Internet Institute analysis of Wikipedia data. Support was provided by the IDRC.
