OPERA Dynamic Surface Water Extent from Sentinel-1 (Version 1)

This dataset contains Level-3 Dynamic OPERA Surface Water Extent from Sentinel-1 (DSWx-S1) product version 1. 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 illumination that often pose challenges to optical sensors. Forward production of the...本数据集包含哨兵-1号（Sentinel-1）衍生的三级动态OPERA地表水体范围（DSWx-S1）V1版本产品。DSWx-S1可在军事格网参考系统（MGRS）格网体系下，以30米的空间分辨率实现近乎全球的陆地区域地表水体范围地理制图，时间重访周期为6至12天。该产品依托哨兵-1号的雷达观测数据，可识别宽度大于200米、面积超过3公顷的开放内陆水体，不受常对光学传感器造成困扰的云量条件与日照光照限制。本数据集的正向生产工作……
