This map was derived from synthetic aperture radar (SAR) images acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) from 05 April 2022 to 02 October 2022.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Suggested Use:</SPAN></P><P><SPAN>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 the Media reports and other images.</SPAN></P><P><SPAN>This damage proxy map should be used as guidance to identify damaged areas or areas affected by flood and may be less reliable over vegetated areas. The changes in radar reflections from flooded land and damaged buildings cannot be separated easily. For example, the scattered colored pixels over vegetated areas may be false positives, and the lack of colored pixels over vegetated areas does not necessarily mean no damage.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Satellite/Sensor:</SPAN></P><P><SPAN>Copernicus Sentinel-1 Synthetic Aperture Radar (SAR)</SPAN></P><P><SPAN STYLE="font-weight:bold;">Resolution:</SPAN></P><P><SPAN>30 meters</SPAN></P><P><SPAN STYLE="font-weight:bold;">Credits:</SPAN></P><P><SPAN>Sentinel-1 data were accessed through the Copernicus Open Hub and the Alaska Satellite Facility server. The product contains modified Copernicus Sentinel data (2022), processed by ESA and analyzed by the NASA-JPL/Caltech ARIA team. NASA's Earth Applied Sciences Disasters Program provided part of the funding.</SPAN></P><P><SPAN>For more information about ARIA, visit: </SPAN><A href="http://aria.jpl.nasa.gov:80/" STYLE="text-decoration:underline;"><SPAN>http://aria.jpl.nasa.gov</SPAN></A></P><P><SPAN STYLE="font-weight:bold;">Esri REST Endpoint:</SPAN></P><P><SPAN>See URL section on right side of page</SPAN></P><P><SPAN STYLE="font-weight:bold;">Data Download:</SPAN></P><P><A href="https://aria-share.jpl.nasa.gov:443/202209-Hurricane_Ian_USA/DPM/" STYLE="text-decoration:underline;"><SPAN>https://aria-share.jpl.nasa.gov/202209-Hurricane_Ian_USA/DPM/</SPAN></A></P></DIV></DIV></DIV>
