During my thesis a friend of mine, Jeff Warren of Grassroots Mapping and the MIT Media Lab, introduced me to the concept of open source mapping. When my thesis site – Neft Dashlari (Oil Rocks) showed up on Google Earth only in name – he offered some tips on how to find other maps and posted them to the website. Another example: during the BP Gulf Oil Spill the group used grassroots mapping to map the extent of the oil spill – thereby offering an alternate narrative to the one told by the mainstream press.

GeoFabrik Web Site
Geofabrik was created out of the conviction that free geodata created by projects like OpenStreetMap will become increasingly attractive for commercial uses.
