Haiti was a proving ground for new technologies that allow people to share and access vital information during times of crisis. Like Ushahidi, which also was deployed in Haiti after the earthquake, Google's Crisis Response — a clearinghouse of satellite imagery, scientific data and video on a single Google map — was used to monitor rescue efforts in Haiti.
