Andrew Curtis, who leads the Geographic Information Systems Health and Hazards Lab at Kent State University, is using mapping techniques to research how communities recover in the wake of a disaster. During a recent visit to Joplin, Mo., he used a car outfitted with video cameras to study the area that a tornado struck last year. "We have a street view of all of these roads that were in the path of the tornado. We are looking at why places returned and how they got there. We are mapping how a community grows and develops in the face of a disaster like this," said Curtis, who was helped by Steve Smith, an associate professor of geography at Missouri Southern State University.
