Ushahidi

Ushahidi (Kiswahili for "testimony" or "witness") is a website created in the aftermath of Kenya's disputed 2007 presidential election (see ) that collected eyewitness reports of violence sent in by email and text-message and placed them on a Google map. It is also the name of the open source software developed for that site, which has since been improved, released freely, and used for a number of similar projects.

Ushahidi uses the concept of crowdsourcing for social activism and public accountability, serving as an initial model for what has been coined as 'activist mapping' - the combination of social activism, citizen journalism and geospatial information. Ushahidi provides a mechanism for local observers to submit reports using their mobile phones or the internet, while simultaneously creating a temporal and geospatial archive of events.

Post-Kenya crisis uses
According to Wikipedia, the software has since been used in other countries including South Africa, India and Mexico, and during 2010 after the earthquakes in Haiti and Chile.
