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 (2025), processed by ESA and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS). 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.
