摘要：The Geospatial Information Authority of Japan (GSI) has put forward its best efforts to support the victims and damaged regions by surveying and providing geospatial information, for example, distributing maps and aerial photos, observing crustal movement and mapping inundation areas as quickly as possible. The “tsunami flood area overview map” it provided has been particularly useful in various geographical anal- yses of tsunami damage. This paper summarizes the activities of the GSI in response to the Great East Japan Earthquake of 2011 off the Pacific coast of the Tohoku region, and some of the results of its analyses of the relationship between tsunami damage and geographic conditions such as land use, elevation and land condition.
