m2s2-SITS

m2s2-SITS consists of satellite imagery from randomly sampled geographic locations within France and South Sudan, with a period of approximately one year. Our dataset contains the full 12-band multispectral imagery from optical S2 and the 2 polarizations from radar S1. Specifically, we collect a pretraining dataset over France that contains 5314 time series with a total of 731,000 Sentinel 1 radar images and 90,000 Sentinel 2 optical images. Our Africa pretrain dataset contains 5941 time series, with 193,000 Sentinel 1 radar images and 70,000 Sentinel 2 optical images.

m2s2-SITS数据集包含采自法国与南苏丹境内随机选取地理点位的卫星影像，观测周期时长约为一年。本数据集涵盖光学传感器Sentinel 2（S2）的全部12波段多光谱影像，以及雷达传感器Sentinel 1（S1）的2种极化方式数据。具体而言，法国区域预训练数据集包含5314条时间序列，总计包含731000张哨兵1号雷达影像与90000张哨兵2号光学影像；非洲区域预训练数据集则包含5941条时间序列，涵盖193000张哨兵1号雷达影像与70000张哨兵2号光学影像。
