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. The product contains modified Copernicus Sentinel data (2023-2024), processed by ESA and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS). This map was derived from synthetic aperture radar (SAR) images acquired by the ALOS-2 satellite operated by the Japan Aerospace Exploration Agency (JAXA) before (22 Nov 2022 and 6 Jun 2023) and after (2 Jan 2024) the event. This map was derived from synthetic aperture radar (SAR) images acquired by the ALOS-2 satellite operated by the Japan Aerospace Exploration Agency (JAXA) before (20 Jun 2022 and 26 Sep 2022) and after (1 Jan 2024) the event. 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.
