Dynamic Surface Water Extent from Sentinel-1 (DSWx-S1) V1
This dataset contains Level-3 Dynamic OPERA surface water extent from Sentinel-1 (DSWX-S1). DSWx-S1 provides near-global geographical mapping of surface water extent over land at a spatial resolution of 30 meters over the Military Grid reference System (MGRS) grid system, with a temporal revisit frequency between 6-12 days. Using Sentinel-1 radar observations, DSWx-S1 maps open inland water bodies greater than 3 hectares and 200 meters in width, irrespective of cloud conditions and daylight illu
