Summary:
The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology in Pasadena, California, in collaboration with the Earth Observatory of Singapore (EOS), created this Damage Proxy Map (DPM) depicting areas that are likely damaged caused by the heavy rains and flooding in Japan. The map was derived from synthetic aperture radar (SAR) images from the JAXA ALOS-2 satellite. This map shows areas which are likely damaged in Kumamoto Prefecture, Japan due to heavy rains since 3 Jul. Damage is shown by coloured pixels of 30 m in size, where yellow to red indicates increasingly significant ground surface change before and after the event. Derived from synthetic aperture radar data acquired by the ALOS-2 satellites operated by the Japan Aerospace Exploration Agency (JAXA) before (2 Mar, 8 Jun) and after (6 Jul) the event. ALOS-2 data were provided by Sentinel Asia. Analysed by the ARIA-SG team at the Earth Observatory of Singapore (EOS) in collaboration with NASA-JPL and Caltech.
This damage proxy map should be used as guidance to identify damaged areas, and may be less reliable over vegetated areas. For example, the scattered colored pixels over vegetated areas may be false positives, and the lack of colored pixels over vegetated areas does not necessarily mean no damage. This map is most sensitive to building damage, but small scale change or partial structural damage may not be detected by this map.
Suggested Use:
This damage proxy map shows surface change with yellow to red indicating more significant change or building damage due to the cyclone. The damage proxy map should be used as guidance to identify damaged areas and may be less reliable over vegetated areas. The lack of colored pixels over vegetated areas does not necessarily mean no damage. Small scale change or partial structural damage may not be detected by this map.
