So2Sat LCZ42

So2Sat LCZ42 is a dataset consisting of co-registered synthetic aperture radar and multispectral optical image patches acquired by the Sentinel-1 and Sentinel-2 remote sensing satellites, and the corresponding local climate zones (LCZ) label. In this version of the dataset, we included additionally the label confidence evaluation data. Ten European cities in the city list were re-labeled by having a group of remote sensing experts cast 10 independent votes on a subset of the originally labeled polygons. They were then split into geographically separated training and testing data. The latter is furthermore split randomly into testing and validation data.So2Sat LCZ42是一款由哨兵一号（Sentinel-1）与哨兵二号（Sentinel-2）遥感卫星采集的共配准合成孔径雷达（synthetic aperture radar）图像块及多光谱光学图像块，与对应局地气候区（LCZ）标签组成的数据集。本版本数据集额外纳入了标签置信度评估数据。针对城市列表中的10座欧洲城市，研究团队组织一组遥感专家对其原始标注多边形的子集开展10次独立投票，以此完成重新标注。随后将相关数据按地理区域划分为训练集与测试集，其中测试集进一步被随机划分为测试数据与验证数据。
