A Design of Reduced Data Representation for Information Sharing in the Disaster-Affected Area

We have proposed the shared disaster information service system for exchanging automatic disaster information among all the shelters. However, it is necessary to accumulate much disaster information in the microcomputer which has restriction in data volume. Moreover, the disaster information must be smoothly transmitted in a comparatively low speed wireless network. In this paper, we propose the data format and conversion algorithm for changing disaster information compactly. Our proposal was verified using disaster information. It was shown that it is possible enough for our verification to exchange and share the disaster information accumulated in the microcomputer in the city with about 200,000 populations.
