Disaster Response Activities of Geospatial Information Authority of Japan to Typhoon Hagibis in 2019

Abstract

Typhoon Hagibis brought torrential rain across eastern Japan in October 2019. This rain eventually caused floods and landslides in many parts of the affected areas. The death toll from the typhoon climbed to 104. Geospatial Information Authority of Japan (GSI), which is one of the designated government oraganizations enacted by the Disaster Countermeasures Basic Act, took aerial photographs, recorded video picture using UAV and produced inundation-depth estimation maps in support of relevant disaster management organizations. These geospatial products were also published on GSI’s website for general use. This article describes GSI’s activities for geospatial production as well as its outreach activities at local level for effective use of geospatial products.
