To help officials locate submerged streets, street signs and landmarks, and reach victims of Hurricane Katrina, Tele Atlas and TomTom donated 300 navigation devices to the Louisiana Department of Transportation, the La. Office of Emergency Preparedness, Federal Emergency Operations in Mississippi and the State of Alabama Emergency Management Agency. Tele Atlas also worked with ESRI to provide GIS software, data and services support to various organizations to identify neighborhoods that were underwater, or find victims in otherwise unidentifiable locations. In this plenary session, Don Cooke of Tele Atlas discusses the role GPS technology played in supporting emergency efforts in the aftermath of the hurricanes.
