Ushahidi is a non-profit software company that develops free and open source software for information collection, visualization and interactive mapping.
The organization 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 offers products that enable local observers to submit reports using their mobile phones or the internet, while simultaneously creating a temporal and geospatial archive of events. (wikipedia)
