EOS-RS Damage Proxy Map (Copernicus Sentinel-1) for the August 2023 Hawai'i Wildfires

Date of Image: 8/13/2023 Date of Next Image: Unknown Summary: The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this preliminary Damage Proxy Map (DPM) depicting areas that are likely damaged in Maui County, Hawaii due to wildfires that started in early August 2023. This map was derived from synthetic aperture radar (SAR) images acquired by the Copernicus Sentinel-1 satellite operated by the European Space Agency (ESA) before (15 Apr to 1 Aug 2023) and during (13 Aug 2023) the event. Suggested Use: The colour variation from yellow to red indicates increasingly more significant surface change. Preliminary validation was done by comparing with high-resolution optical imagery (Maxar FirstLook and Copernicus Sentinel-2) and media reports. This map could be used as a guidance 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.
