Check out this handy Creativity article on how new media is helping the rescue and relief efforts in Haiti. Among the initiatives Tali Krakowsky cites are:

Ushahidi is an open source project which allows users to crowdsource crisis information to be sent via mobile. They have created a Crisis Map of Haiti in collaboration with International Network of Crisis Mappers. The map represents a comprehensive and up-to-date crisis overview for to the humanitarian community.

Google collaborated with satellite imagery company GeoEye to make images of the destruction available in Google Earth and Google Maps. The goal is to create a helpful tool for aid organizations.

Crisis Commons is a volunteer network of professionals that create technological tools and resources for mitigating disasters and crisis around the world. They have has set up Crisis Camps, all-day events in which people help build a variety of online tools to help disaster response in Haiti. Crisis Commons has also created a Haiti OpenStreetMap with the most complete digital map of Haiti’s roads, hospitals, triage centers and refugee camps currently available – the kind of street maps that save lives.

Skype and Google are offering free calls from Haiti. Google Voice is directly offering free calls from its website and Skype is sending vouchers for an hour’s worth of calls to the US to every Skype user already registered in Haiti.

Within a few hours of the crisis, a Google Group called Haitian Earthquake Registry was set up as an online person finder database to help Haitians in and out of the country locate missing relatives, which currently contains more than 54,000 records. Leveraging the kind of technology that we use for online dating, this platform re-unites families.

We Have We Need is a project created in partnership with the U.S. State Department to create a Craigslist-style site where nonprofits working in Haiti can post needs and requests and find donors.
