The data from the B01_WTR layer represents pixel-wise classification into one of three water classes (not water, open water, and inundated vegetation), masked areas (including height threshold and layover/radar shadow), or no data classes.</span></p><p><span style='font-weight:bold;'>Data Sources:</span></p><p><span>The Dynamic Surface Water eXtent (DSWx) products map pixel-wise surface water detections using optical or SAR imagery.</span></p><p><span>The Advanced Rapid Imaging and Analysis (ARIA) and Observational Products for End-Users from Remote Sensing Analysis (OPERA) teams at NASA's Jet Propulsion Laboratory and California Institute of Technology derived the surface water extent flood maps using the OPERA Dynamic Surface Water Extent (DSWx) from NASA Harmonized Landsat Sentinel-2 (HLS) products.</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 inundation extent.</span></p><p><span>For more information about the Dynamic Surface Water eXtent product suite, please refer to the DSWx Product page: https://www.jpl.nasa.gov/go/opera/products/dswx-product-suite</span></p><p><span>For more information about the Caltech-JPL ARIA project, visit https://aria.jpl.nasa.gov</span></p><p><span style='font-weight:bold;'>Suggested Use:</span></p><p><span>The OPERA DSWx-HLS Water product classifies the Harmonized Landsat Sentinel-2 (HLS) input imagery into "not water", "open surface water", and “partial surface water”. The "HLS cloud/cloud shadow" and "HLS snow/ice" layers are direct inputs from the HLS FMask.</span></p><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><p><span>Areas with no water detected are white. An area with valid data that is not water, snow/ice, cloud/cloud shadow, or ocean masked.</span></p><p><span>Note: 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 Water product classifies data: https://d2pn8kiwq2w21t.cloudfront.net/documents/ProductSpec_DSWX_URS309746.pdf</span></p><p><span style='font-weight:bold;'>Satellite/Sensor:</span></p><p><span>Sentinel-1A satellite (ESA Copernicus)</span></p><p><span style='font-weight:bold;'>Data Availability:</span></p><p><span>The DSWx-S1 data product is not yet in production.
