在 Radiance Scale Factors 对话框中选择Use single scale factor for all bands ( Single scale factor : 1 ),在辐射定标中对单位进行了转换。 单击Output Reflectance File 按钮选择输出文件名和路径。 (2)传感器与图像目标信息 l Lat : 40 19 39.46 , Lon : 116 42 2.98 ( FLAASH 自动获取) l Sensor ...
1)在ENVI的Toobox中,选择Radiometric Correction>Radiometric Calibration,选择多光谱数据(MultiSpectral多光谱数据(1~7波段)、Panchromatic 全色波段数据(8波段)、Cirrus卷云波段数据(9波段)、Thermal热红外数据(10,11波段)、Quality质量波段数据(12波段))。 2)设置参数 Calibration Type定标的类型:radiance(辐射率)、refl...
In a prior paper, CMAC closely agreed with LaSRC software for correction of the four VNIR bands of Landsat-8/9 images for conditions of low to moderate atmospheric effect over quasi-invariant warehouse-industrial targets. Those results were accepted as surrogate surface reflectance to sup...
