Philippines Typhoon Mindanao: Flood Proxy Map, Jul 2026

# EOS-RS Flood Proxy Map: Philippines, Storm Nalgae (Paeng), 27 Oct 2022, v0.4 The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this preliminary Flood Proxy Map (FPM) depicting areas that are likely flooded in Mindanao, Philippines due to heavy rains brought about by Tropical Storm Nalgae (Paeng). This map was derived from synthetic aperture radar (SAR) images acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) before (15 Oct 2022) and during (27 Oct 2022) the event. The image covers an area indicated by the large white polygon. Each light blue pixel measures about 30m across. Preliminary validation was done by comparing with media reports. This flood proxy map should be used as a guide to identify areas that are likely flooded, and is less reliable over urban and vegetated areas. The product contains modified Copernicus Sentinel data (2022), processed by ESA and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), using the Advanced Rapid Imaging and Analysis (ARIA) system originally developed at NASA's Jet Propulsion Laboratory, California Institute of Technology, and modified at EOS-RS. **More map details and files:** **More map details and files:** **Credits:** Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), Advanced Rapid Imaging and Analysis (ARIA), NASA-JPL/Caltech, Contains modified Copernicus Sentinel data (2022)
