2010年北京市国际空间站ISS夜光影像数据

原始数据来源于国际空间站2010年12月14日拍摄的ISS夜光图片，空间分辨率约60米，RGB彩色图像。对北京ISS夜光图像进行地理配准，基于伪不变特征（Pseudo Invariant Feature，PIF）的相对辐射归一化处理。处理后的影像具有地理坐标和辐射一致性，可以用于不同时间、不同城市间的时空对比分析。

The raw dataset is derived from nighttime light images captured by the International Space Station (ISS) on December 14, 2010. These are RGB color images with a spatial resolution of approximately 60 meters. Georegistration and relative radiometric normalization based on Pseudo Invariant Features (PIFs) were performed on the ISS nighttime light image of Beijing. The processed imagery has consistent geographic coordinates and radiometric consistency, and can be utilized for spatiotemporal comparative analysis across different times and cities.
