CONSTRUCTION OF GLOCAL MONITORING SYSTEM FOR DISASTER MONTORTNG

摘要

In 2016, Tokai University initiated a new project call "Constructing glocal monitoring system for safe and secure society", "glocal" is a coined word of "global" and "local". The main concept of the project is to connect global monitoring system using satellite observation with local monitoring system using SNS for monitoring disasters and environmental changes. The project was selected by the Ministry of Education, Culture, Sports, Science and Technology(MEXT) of Japan as one of the Research Branding Project of Private Universities in Japan supported by NEXT for five years. Tokai University is receiving satellite data such as MODIS, VIIRS and AVHRR data at its ground station in Shonan Campus located in Kanagawa Prefecture, Japan. The data are automatically processed and archived in near real time. The authors are utilizing the data for various purposes including disaster monitoring. On the other hand, the authors has been developing a Twitter-based disaster-related information sharing system which is composed of the following two subsystems; (1) DITS (Disaster Information Tweeting System): a system that inserts both the user's current geo-location information (street address) and the hashtag of the form "#(municipality name) disaster" to a tweet automatically, (2) DIMS (Disaster Information Mapping System): a system that plots tweets posted via DITS on a digital map. The authors are constructing the Glocal Monitoring System by connecting the satellite data system with the twitter-based system.
