A proposal of disaster information system based on the Internet technologies

This research develops an Autonomous Distributed and Cooperative disaster information system based on the Internet technologies which distribute sensor information such as meteorological information. It is essential that disaster prevention systems collect and classify information or deliver to local residents rapidly. However, there are some problems with information sharing among some agencies because these systems have been constructed independently and lack uniformity and scalability. It is difficult to construct the systems which can share information in common for the initial cost and government´s administrative structure. These problems cause delays in information distribution. We develop a common infrastructure which can ensure uniformity, scalability and low-cost construction within a jurisdiction. It enables every agency to use all kinds of disaster information in common and has scalability corresponding to the changing information or media with an aim of rapid distribution.
