Responses of GSI to the Kanto-Tohoku Heavy Rainfall Disaster in September 2015－Aerial Photographs and Presumed Inundation-Area Maps of Joso district－

Abstract

In case of a large scale natural disaster, Geospatial Information Authority of Japan (GSI) provides necessary geospatial information to contribute to lifesaving rescue activities and disaster recovery measures operated by relevant disaster management organizations (DMOs). When the Kanto-Tohoku Heavy Rainfall Disaster in September 2015 occurred, GSI took aerial photographs and unmanned aerial vehicle movies, and produced presumed inundation-area maps of Joso district to supply DMOs with such geospatial information.
