{ "currentVersion": 11.5, "serviceDescription": "OPERA Level-3 Dynamic Surface Water Extent (DSWx) product from Harmonized Landsat-8/9 and Sentinel-2A/B/C (HLS), processed and developed by OPERA (JPL/USGS). Values for B01 WTR are a masked interpreted water classification layer. This represents pixel-wise classification into one of three water classes (not water, open water, and partial surface water), HLS snow/ice, HLS cloud/cloud shadow and adjacent to cloud/cloud shadow, or no data classes.\n\nThis dataset contains Level-3 Dynamic OPERA surface water extent product version 1. The data are validated surface water extent observations beginning April 2023. Known issues and caveats on usage are described in the Product Documentation. The input dataset for generating each product is the Harmonized Landsat-8 and Sentinel-2A/B/C (HLS) product version 2.0. HLS products provide surface reflectance (SR) data from the Operational Land Imager (OLI) aboard the Landsat 8 satellite and the MultiSpectral Instrument (MSI) aboard the Sentinel-2A/B/C satellite. The surface water extent products are distributed over projected map coordinates using the Universal Transverse Mercator (UTM) projection. Each UTM tile covers an area of 109.8 km × 109.8 km. This area is divided into 3,660 rows and 3,660 columns at 30-m pixel spacing. This EGIS service offers access to the water classification data layer.\n\nMore information about the dataset is available at https://www.earthdata.nasa.gov/data/catalog/pocloud-opera-l3-dswx-hls-v1-1.0\n\nOPERA was informed by the Satellite Needs Working Group (SNWG), an interagency effort of the U.S. Government dedicated to identifying and addressing Earth observation needs across U.S. civilian federal agencies.\n\nFor questions about this service, please contact podaac@podaac.jpl.nasa.gov\n", "serviceItemId": "59caecb96b5b42dd85aa3001a10f7786", "name": "C2617126679-POCLOUD/OPERA_L3_DSWX-HLS_V1_B01_WTR", "description": "OPERA Level-3 Dynamic Surface Water Extent (DSWx) product from Harmonized Landsat-8/9 and Sentinel-2A/B/C (HLS), processed and developed by OPERA (JPL/USGS).
