Preliminary Flood Mapping in East Japan after the Typhoon Hagibis

On October 12, 2019, the Typhoon Hagibis hit East Japan, triggering floods and landslides. The Geoinformatics Unit, RIKEN Center for Advanced Intelligence Project conducted a preliminary mapping of the affected areas using Sentinel-1 SAR data provided by ESA.

We are a RESEARCH GROUP in Tokyo
specialized in Remote Sensing and Geoinformatics

Geoinformatics Unit aims to develop intelligent systems that monitor and assess the state and changes of urban areas and natural environments from large-scale time-series geospatial data. We study fundamental technologies of geospatial data analysis that can deal with data incompleteness, limited training data, and multimodality. Our applied research includes disaster response, urban planning, and forest monitoring.
