There are some problems in heavy rain disasters. Especially, it is difficult to grasp the damage situation at the time of a disaster. It is important to grasp the accurate information quickly and to share theinformation among administrators in times of disaster, in order to operate in real time, during disasters to minimize damages. We established an immediate action support system, based on the GIS to operate in real time, during disasters. The purpose of this system is to get the accurate information on the disaster situations and to display the appropriate measures, for immediate action. This system consists of two parts. One is a collecting-information support system and the other is an action support system.
