In particular, the flood maps were created by stitching relevant tiles from the Binary Water (B02_BWTR) layer covering the period of September 03-10, 2023. The OPERA DSWx-HLS Binary Water product classifies the Harmonized Landsat Sentinel-2 (HLS) input imagery into "not water" and "water".</span></p><p><span>The results posted here are preliminary and unvalidated results, primarily intended to aid the field response and people who wanted to have a rough first look at the flood extent. The ARIA-share website has always focused on posting preliminary results as fast as possible for disaster response. </span></p><p><span>The post-processed products are available to download at </span><a href='https://aria-share.jpl.nasa.gov:443/202308_Florida_Hurricane_Idalia/DSWx-HLS/' rel='nofollow ugc' style='text-decoration:underline;'><span>https://aria-share.jpl.nasa.gov/202308_Florida_Hurricane_Idalia/DSWx-HLS/</span></a><span>. The OPERA DSWx-HLS products are freely distributed to the public via NASA's Physical Oceanography Distributed Active Archive Center (PO.DAAC) and can be downloaded through NASA's Earthdata search.

The "cloud/cloud shadow" and "snow/ice" layers are direct inputs from the HLS FMask. </span></p><ul><li><p><span> Areas with water detected are blue. An area classified as "open water" or "partial surface water" in the OPERA WTR layer.</span></p></li><li><p><span> Areas with clouds or cloud shadows are light gray. An area identified as cloud, cloud shadow, or adjacent to cloud/cloud shadow according to input HLS quality assurance (QA) data.</span></p></li><li><p><span> Areas labeled as ice/snow are cyan. An area identified as snow/ice according to input HLS quality assurance (QA) data.</span></p></li><li><p><span> Areas with no water detected are transparent. An area with valid data that is not water, snow/ice, cloud/cloud shadow, or ocean masked.</span></p></li></ul><p><span>This layer is meant to provide users with a quick view for water/no-water. Invalid data classes (snow/ice and cloud/cloud shadow along with adjacent to cloud/cloud shadow) are also provided to indicate areas in which the binary classification does not provide water/no-water classification.</span></p><p><span style='font-weight:bold;'>Note</span><span>: Sediment rich water is sometimes misclassified as snow/ice by the HLS QA mask.</span></p><p><span>For more information about how the OPERA DSWx-HLS Binary Water product classifies data: </span><a href='https://d2pn8kiwq2w21t.cloudfront.net:443/documents/ProductSpec_DSWX_URS309746.pdf' rel='nofollow ugc' style='text-decoration:underline;'><span>https://d2pn8kiwq2w21t.cloudfront.net/documents/ProductSpec_DSWX_URS309746.pdf</span></a></p><p><span style='font-weight:bold;'>Satellite/Sensor:</span></p><p><span>Harmonized Landsat Sentinel-2 (HLS)</span></p><ul><li><p><span> Landsat 8 Operational Land Imager (OLI)</span></p></li><li><p><span> MultiSpectral Instrument (MSI) on European Space Agency's (ESA) Copernicus Sentinel-2A/2B satellites</span></p></li></ul><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>NASA JPL-Caltech ARIA Team, NASA, NASA Disasters Program</span></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;'>WMS Endpoint:</span></p><p><a href='https://maps.disasters.nasa.gov/ags04/services/hurricane_idalia_2023/aria_watermaps/MapServer/WMSServer' rel='nofollow ugc' target='_blank'>https://maps.disasters.nasa.gov/ags04/services/hurricane_idalia_2023/aria_watermaps/MapServer/WMSServer</a><span style='font-weight:bold;'><br /></span></p><p><span style='font-weight:bold;'>Data Download:</span></p><p><a href='https://aria-share.jpl.nasa.gov:443/202308_Florida_Hurricane_Idalia/DSWx-HLS/' rel='nofollow ugc' style='text-decoration:underline;'><span>https://aria-share.jpl.nasa.gov/202308_Florida_Hurricane_Idalia/DSWx-HLS/ </span></a></p></div></div></div> |
