Color Vision Deficiency (CVD) Version

NOTE: This damage proxy map could be used as a guidance to identify damaged areas particularly in more urban areas, and may be less reliable over vegetated areas and in the mountains. Scattered pixels over vegetated areas may be false positives, and a lack of colored pixels over vegetated areas may not mean no damage.Date of Image:9/11/2023Date of Next Image:UnknownSummary:The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this Damage Proxy Map (DPM) depicting areas that are likely damaged in Morocco due to the M6.8 earthquake that occurred on 8 Sep 2023. This map was derived from synthetic aperture radar (SAR) images acquired by the Copernicus Sentinel-1 satellite operated by the European Space Agency (ESA) before (26 May 2023 and 30 Aug 2023) and after (11 Sep 2023) the event.Suggested Use:Standard Version: The color variation from pale yellow to red indicates increasingly more significant surface change (drop in radar reflection coherence). Preliminary validation was done by comparing with high-resolution optical imagery and media reports.Color Vision Deficiency (CVD) Version: The color variation from light blue to dark blue indicates increasingly more significant surface change. Preliminary validation was done by comparing with high-resolution optical imagery and media reports.NOTE: This damage proxy map could be used as a guidance to identify damaged areas, and may be less reliable over vegetated areas and in the mountains. Scattered pixels over vegetated areas may be false positives, and a lack of colored pixels over vegetated areas may not mean no damage.Satellite/Sensor:Copernicus Sentinel-1 Synthetic Aperture Radar (SAR)Resolution:30 metersCredits:Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), Contains modified Copernicus Sentinel data (2023), Validated with FirstLook Imagery © 2023 Maxar Esri REST Endpoint:See URL section on right side of pageWMS Endpoint:https://maps.disasters.nasa.gov/ags04/services/morocco_earthquake_202309/eos_dpm/MapServer/WMSServerData Download:https://eos-rs-products.earthobservatory.sg/EOS-RS_202309_Morocco_Earthquake/
