The Ball Aerospace & Technologies Corporation is building Landsat 9’sOperational Land Imager 2(OLI-2). OLI-2 will take measurements in the visible, near infrared, and shortwave infrared portions of the electromagnetic spectrum. The spatial resolution of its images will be 15 m (49 ft) for th...
Both instruments have sensors with moderate spatial resolution—15 m (49 ft), 30 m (98 ft), and 100 m (328 ft)depending on spectral band—and the ability to detect a higher range in intensity than Landsat 8 (14-bitradiometric resolution vs. Landsat 8's 12-bit radiometric resolution). ...
该数据集包含从Landsat 9 OLI/TIRS传感器产生的数据中提取的大气校正表面反射率和地表温度。这些图像包含5个可见光和近红外(VNIR)波段和2个短波红外(SWIR)波段,这些波段被处理成正射的表面反射率,还有一个热红外(TIR)波段被处理成正射的表面温度。它们还包含用于计算ST产品的中间波段,以及QA波段。 Landsat 9 SR产...

Google Earth Engine(GEE)——landsat 8 和9影像集合SR_B6无法进行映射,所有目前对于所有的C02数据中,Landsat8和5的地表反射率中,无法进行温度波段的映射和转换。只有Landsat9是ok的。上面的代码
不再需要使用 Ermida 的算法计算表面温度。 Landsat Level 2,Collection 2 包含经大气校正的地表反射率和地表温度 (LST)。所有 Collection 2 LST 产品均采用由罗彻斯特理工学院 (RIT) 和美国国家航空航天局 (NASA) 喷气推进实验室 (JPL) 联合开发的单通道算法创建。
Collection 1包含自1972年至今Landsat-1~8所有Level-1级数据,Landsat 9的数据只在Collection中提供。值得注意的是,对于Collection 1的处理只持续到2021年12月31日,在此期间Collection 2也在同步处理,但从2022年1月1日起获取的Landsat数据将只被处理到Collection 2中。MODIS(Moderate Resolution Imaging Spectroradiometer)...
