Sentinel-2 Spectral Signals

该数据集包含了从Afrobarometer数据点中提取的地理定位信息，这些数据点关于受访者的屋顶类型，使用的是哨兵2号Level-1C产品的光谱信号。这些光谱信号被用于预测非正式定居点的屋顶材料。目前，该数据集正在扩展中，以纳入更多的哨兵2号光谱信号和材料注释，以便对预测结果进行稳健的验证。每个类别包含11个Level-1C光谱信号，注释各不相同。该数据集的任务是基于屋顶材料类型来检测和绘制非正式定居点的地图。

This dataset includes geospatial information extracted from Afrobarometer data points pertaining to the roof types of survey respondents, combined with spectral signals derived from Sentinel-2 Level-1C products. These spectral signals are utilized to predict the roofing materials of informal settlements. Currently, the dataset is being expanded to incorporate more Sentinel-2 spectral signals and material annotations, allowing for robust validation of the prediction outcomes. Each roofing material category contains 11 Level-1C spectral signals with distinct annotations. The task of this dataset is to detect and cartographically map informal settlements based on the types of roofing materials.
