2020年第四季度山东省Landsat8蓝光波段30米地表反射率合成产品

Landsat8地表反射率季度合成产品首先进行大气校正反演未经地形校正的地表反射率；再利用地形校正算法结合云掩膜进行非云地区的山地地表反射率地形校正，最终获得高质量的地表反射率产品。（协议共享）

The Landsat8 surface reflectance quarterly composite product is produced via the following workflow: Firstly, atmospheric correction is conducted to retrieve the surface reflectance without topographic correction; then, a topographic correction algorithm combined with cloud mask is applied to perform topographic correction on mountainous surface reflectance in cloud-free regions; finally, high-quality surface reflectance products are obtained.
