Ushahidi platform
Ushahidi is an open source software application that collates and maps data using user-generated reports. It uses the concept of crowdsourcing serving as an initial model for what has been coined as "activist mapping" – the combination of social activism, citizen journalism and geographic information. Ushahidi allows local observers to submit reports using their mobile phones or the Internet, creating an archive of events with geographic and time-date information.
