Abstract
The use of former edition maps for disaster risk learning is effective, but requires
proficiency of instructors. In this study, we developed a spatiotemporal GIS with many
layers in addition to the former edition maps, and applied it to a special exhibition on the
Typhoon Vera (the Isewan Typhoon) in 1959, Japan. And we evaluated the effectiveness of
spaciotemporal GIS from the system logs and the questionnaire survey to the visitors. The
results showed that a certain percentage of users used the spaciotemporal GIS for scenariobased
learning, and this percentage increased in conjunction with the special exhibition. At
the same time, the results of the questionnaire survey showed an improvement in the user’s
satisfaction. From these results, the effectiveness of the method was confirmed.
