资源简介:
This dataset contains globally distributed Sentinel-1 SAR image patches (512×512 pixels) acquired using dual polarizations (VV and VH) and both ascending and descending orbits.
Each sample includes:
(i) Single-acquisition SAR images (noisy input)
(ii) Ground-truth images generated through multitemporal averaging using 5, 10, 15, 20, and 25 acquisitions
(iii) Corresponding ESA WorldCover land cover maps
(iv) A metadata CSV file containing geographic coordinates and Google Earth Engine identifiers.
The dataset is designed for supervised training and benchmarking of SAR despeckling algorithms and multitemporal fusion strategies.
本数据集包含全球分布式的Sentinel-1合成孔径雷达(SAR)图像块(尺寸为512×512像素),采集采用双极化模式(VV与VH极化),且覆盖升轨与降轨两种轨道方向。
每个样本包含:
(i) 单次采集合成孔径雷达图像(含噪输入样本);
(ii) 通过对5、10、15、20及25次采集结果进行多时间平均生成的真值图像;
(iii) 对应欧洲空间局(ESA)WorldCover土地覆盖图;
(iv) 附带包含地理坐标与谷歌地球引擎(Google Earth Engine)标识符的元数据CSV文件。
本数据集旨在用于合成孔径雷达(SAR)去斑算法与多时间融合策略的监督训练及性能基准测试。
