Geo-Wiki is a global network of volunteers who wish to help improve the quality of different thematic datasets globally. Competitions are set up in order to mass crowdsource on a special research question. So far the Geo-Wiki Team has run three competitions on (1) Human Impact, (2) Disagreement and (3) Wilderness. In addition to this the Geo-Wiki Team took part in the USAID Hackathon "Hacking for Hunger" on 14/15th of September 2012.
Currently we are not running a competition. However, if you want to keep updated, join us on facebook or sign up for the geo-wiki mailing list.
