EOS-RS Damage Proxy Map: Philippines, Tropical Cyclone Agaton (Megi), Apr 2022, v0.4

The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this preliminary Damage Proxy Map (DPM) depicting areas that are likely damaged by landslides and floods in Leyte, Philippines due to Tropical Cyclone Agaton (Megi) which made landfall on 11 Apr 2022. This map was derived from synthetic aperture radar (SAR) images acquired by the ALOS-2 satellites operated by the Japan Aerospace Exploration Agency (JAXA) before (12 June and 11 Dec 2021) and after (16 Apr 2022) the event.

The image covers an area indicated by the large white polygon. Each pixel measures about 30 meters across. The colour variation from yellow to red indicates increasingly more significant surface change. Preliminary validation was done in selected areas using aerial and ground imagery of landslides. This damage proxy map could be used as a guide to identify damaged areas, and may be less reliable over vegetated areas. Scattered pixels over vegetated areas may be false positives, and a lack of colored pixels over vegetated areas may not mean no damage

Data were provided by Sentinel Asia and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS).
