Tiled Display Environment to Realize GIS Based Disaster Information System

Understanding of damage information in disaster situation is the most important role for emergency response headquarters in order to provide relief action. Although responder in actual large-scale disaster situation could not deal damage situation easily that is ascribable to difficulty for understanding of spatiotemporally damage information. This paper proposes a GIS based disaster situation displaying and sharing approach system for represent disaster damage information at emergency response headquarters in large-scale disaster, to provide association between geolocation and multimedia content which is taken into disaster affected area. Our approach presents images of damage situation upon digital map on a high resolution single and large sized display, allows helping of damage by detail of damage situation in specific area not only showing it. We designed system architecture, use case of system and human computer interaction under operation for damage situation collection on large scale tiled display system. This system can be connected multiple counter disaster sites each other with disaster controlling network in an effort to share digital pictures and/or videos of disaster situation. We also discuss task oriented intuitive input method for our disaster information GIS. We will use some tablet devices in each site to make considerations interaction of system with multiple users.
