You need to know about Ushahidi – they are currently among the most important groups applying ICT in the human rights/humanitarian arena. “The Ushahidi Platform allows anyone to gather distributed data via SMS, email or web and visualize it on a map or timeline. Our goal is to create the simplest way of aggregating information from the public for use in crisis response.”
Ushahidi was used in the aftermath of the Haiti earthquake to receive text messages from those in need, create web-based visualization maps showing where those messages originated from, and filter those messages for the appropriate NGOs.
“Ushahidi is a free and open source project with developers hailing from Kenya, Ghana, South Africa, Malawi, Netherlands and the USA working on it.”
Ushahidi means “testimony” in Swahili. See http://www.ushahidi.com/
