About this dataset

# Pakistan Floods: Damage and Flood Proxy Maps, Aug 2022 The **Earth Observatory of Singapore – Remote Sensing Lab (EOS-RS)** produced these damage and flood proxy maps for Pakistan Floods (Aug 2022) 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 Damage Proxy Map: Pakistan, Floods, 1 Sep 2022, v0.8** - **EOS-RS Damage Proxy Map: Pakistan, Floods, 1 Sep 2022, v0.8** - **EOS-RS Damage Proxy Map: Pakistan, Floods, 30 Aug 2022, v0.8** - **EOS-RS Damage Proxy Map: Pakistan, Floods, 30 Aug 2022, v0.8** - **EOS-RS Damage Proxy Map: Pakistan, Floods, 29 Aug 2022, v0.8** - **EOS-RS Damage Proxy Map: Pakistan, Floods, 29 Aug 2022, v0.8** - **EOS-RS Flood Proxy Map: Pakistan, Floods, 21 Aug 2022, v0.3** **More map details and files:** **More map details and files:** **Credits:** Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), Advanced Rapid Imaging and Analysis (ARIA), NASA-JPL/Caltech, Contains modified Copernicus Sentinel data (2022)

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 (2022), processed by ESA and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), using the Advanced Rapid Imaging and Analysis (ARIA) system originally developed at NASA's Jet Propulsion Laboratory, California Institute of Technology, and modified at EOS-RS. This map was derived from synthetic aperture radar (SAR) images acquired by the ALOS-2 satellites operated by the Japan Aerospace Exploration Agency (JAXA) before (19 Sept 2021) and during (21 Aug 2022) 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.
