Disaster mitigation support system using Twitter and GIS

We can easily get the Tweets from the Twitter and open data about population etc. Therefore we are constructing a system to extract disaster information and analyze Tweet in Twitter by using API (Application Programming Interface), Web service changing geographical information and R etc. If we want to know where is occurring an earthquake, a flood and etc, we could want to get those information which are seismic intensity, weather and traffic conditions. According this study was decided to get those information by using API. And a system which get and show those information are constructed.
