The Information Sharing System Using Web-GIS at the Time of Wide-Scale Disaster

Each local government dispatches the municipal employee to the disaster site in order to check on the damage at the time of wide-scale disaster. The municipal employee take damage images with a digital camera etc., and bring image data back to the disaster countermeasures headquarters. Then, the municipal employee project damage images on a projector and report damage situations. However, this method takes much time for the disaster countermeasures headquarters to grasp damage situations. This may be unable to take a prompt action to disaster sites. In this research, we built the system which reports damage situations to the disaster countermeasures headquarters quickly at the time of wide-scale disaster. In this system, the images and animations of the disaster are automatically mapped on Web-GIS in real time. Thereby, users become possible confirming damage situations at one view from Web-GIS.
