About this dataset

# ARIA-SG Flood Proxy Map: Fiji, Cyclone Harold, 9 Apr 2020, v1.1 Derived from synthetic aperture radar data acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) from 23 Oct 2018 up to 9 Apr 2020. Analysed by the ARIA-SG team at the Earth Observatory of Singapore (EOS) in collaboration with NASA-JPL and Caltech. **More map details and files:**

Documentation

Change detection on synthetic aperture radar (SAR) satellite images acquired before and after the event. Damage Proxy Maps show significant changes in radar coherence and amplitude; Flood Proxy Maps show areas that changed to standing water. Maps are preliminary and checked against news reports and ground-level imagery where available. This product contains modified Copernicus Sentinel data (2020), processed by ESA and analyzed by the Earth Observatory of Singapore. These are preliminary maps derived from satellite radar and should be used as guidance only. Coloured pixels may include false positives, and their absence does not mean an absence of damage or flooding.
