2018年宁夏中宁县哨兵2号10米影像数据

该数据集为2018年中宁县多时相哨兵2号影像，其空间分辨率为10米，有蓝、绿、红和近红外等多个波段，主要应用于构建作物的归一化植被指数等时序特征，为保证构建作物时序特征的最小数据量，部分影像含有少量的云。该数据为欧空局L1C级的大气表观反射率产品，经过了正射校正和亚像元级几何精校正后预处理，数据大小为15.8 GB。This dataset comprises multi-temporal Sentinel-2 imagery of Zhongning County collected in 2018. It has a spatial resolution of 10 meters and multiple bands including blue, green, red, and near-infrared. It is primarily utilized to develop temporal features such as the Normalized Difference Vegetation Index (NDVI) for crops. To maintain the minimum dataset volume for constructing crop temporal features, a small number of images contain trace amounts of clouds. This data is an L1C-level atmospheric apparent reflectance product from the European Space Agency (ESA), and has undergone preprocessing including orthorectification and sub-pixel level geometric precision correction. The total size of the dataset is 15.8 GB.
