DESIGN OF DISASTER STATE PRESENTATION SYSTEM USING ULTRA HIGH RESOLUTION DISPLAY

Management of disaster information is identified as one of the important functions in disaster countermeasure activity once large scale disaster has broken out. Since a large number of disaster information regarding with damage state in aftermath phase are reported to Counter Disaster headquarter (CDH), officers of CDH have to consolidate those to understand the state and to do decision making for quick and correct activity. In conventional, printed large maps are used for disaster management. However, the printed maps are disadvantage because a rapid and flexible reflection of disaster association between the damage state and geographical location cannot be easily attained. On the other hand, a GIS based disaster information system which represents disaster information on a standard display device is proposed and used for small number of disaster officers with relatively small scale of disasters. In this paper we propose LIVEwall by tiled displayed System based presentation and sharing platform for a large disaster case. Our system provides aggregated functions which can visually overlay the damage information on digital map for decision making in the disaster case. The damage state is managed and consolidated and displayed on the digital map on each CDH in local governments. In addition, we propose a shared workspace on the unified shared display device to show both the detail of indicated object and the perspicuity of whole wide area. We consider various interactions between users and tiled display system for both within the same CDH and inter-CDHs as design concept.
