Outline of Final Research Achievements

Characteristics of geospatial information dispatched on the SNS during 20 days since the Great East Japan earthquake occurred are analyzed with using text mining method in the study. Accessibility to evacuate from tsunami quantitatively on the basis of geographical information such as coastal geometry, location of mid-to-high-rise buildings, road network, population distribution, and so on. Finally, structure of the dynamic GIS using real time data of geospatial information including data on the SNS is examined.
