Abstract
Geospatial Information Authority of Japan (GSI) provides information useful to rescue operations and reconstruction for the related organizations which intensively act against actual natural disasters. Typhoon No. 26, which atacked Izu Oshima Island on 15 and 16, October 2013, caused severe damages by debris flow due to heavy rain. GSI urgently took aerial photographs of disaster-affected areas on October 16 (oblique photos) and October 17 (vertical photos) andreleased them with their orthophotos. GSI also provided the website for a smooth provision of various geospatial information which is available to the activities related to the disaster, including results of photo-interpretation.
