Automatic Absolute Radiometric Normalization of Satellite Imagery with ENVI/IDL Programming

Up to present no publication has the detailed description of how to automatically perform the absolute radiometric normalization for satellite imagery based on the Illumination Correction Model (ICM) and Illumination and Atmospheric Correction Model (IACM). In order to achieve the goal, the ENVI/IDL programming method was applied in this study that used ENVI library to extend ENVI and simplify writing routine. It controls complicated routines with no user interaction. Furthermore, the tiling method was implemented when encountering the memory limitation in processing mass remote sensing data.
