Abstract
From the lessons learned in Great Hanshin-Awaji Earthquake, the importance of collection and usage of the disaster information is widely recognized. Most of Japanese local governments have disaster information systems include helicopters with live camera, surveillance camera on top of the building, and so forth. The role of decision support function in disaster information systems will be more important, as the amount of information collected in these systems becomes huge and hard to understand. The authors propose an information visualization system for disaster information, which helps humans to analyze and understand situations from collected data. A prototype system is built and the usability of the system is confirmed with experiments.
