About this dataset

# Sumatra Floods: Damage and Flood Proxy Maps, Nov 2025 The **Earth Observatory of Singapore – Remote Sensing Lab (EOS-RS)** produced these damage and flood proxy maps for Sumatra Floods (Nov 2025) from synthetic aperture radar (SAR) satellite images. Each map is a separate ZIP below with its GeoTIFF, a KMZ for Google Earth, the PNG figures and a text file describing how it was made and how to read it. ## Maps in this dataset - **EOS-RS Flood Proxy Map: Aceh, Indonesia, Floods, 02 Dec 2025, v0.5** - **EOS-RS Damage Proxy Map: North Sumatra, Floods, 28 Nov 2025, v0.9** - **EOS-RS Flood Proxy Map: North Sumatra, Indonesia, Floods, 28 Nov 2025, v0.9** **More map details and files:** **Legal Disclaimer:** **Credits:** Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), Original data ALOS-2 PALSAR-2 Product - JAXA (2022-2025)

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 map was derived from synthetic aperture radar (SAR) images acquired by the ALOS-2 satellite operated by the Japan Aerospace Exploration Agency (JAXA) before (12 Apr 2022) and during (02 Dec 2025) the event. ALOS-2 data was provided by JAXA and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS). 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.
