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 the areas in Montana, United States due to floods caused by heavy rainfall and snowmelt. 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 Feb 2022 - 3 Jun 2022) and after (15 Jun 2022) the event.
Suggested Use:
The color variation from yellow to red indicates increasingly more significant surface change. Preliminary validation was done by comparing with high-resolution optical imagery and media reports.
This map could be used as a guidance to identify damaged areas, and may be less reliable over vegetated areas (such as landslides in vegetated slopes). Scattered pixels over vegetated areas may be false positives, and a lack of colored pixels over vegetated areas may not mean no damage.
Satellite/Sensor:
Copernicus Sentinel-1 Synthetic Aperture Radar (SAR)
Resolution:
30 meters
Credits:
Sentinel-1 data were accessed through the Copernicus Open Hub. This map contains modified Copernicus Sentinel data (2022), processed by ESA and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) in collaboration with NASA-JPL and Caltech.
