We want to convert DN values of Cartosat 2D (PAN and MS) imagery into Surface Reflectance. For that we need the values of bias, gain, scale factor, solar irradiance. We also want to remove Haze.
The best approach is to aquire the calibration document of Cartosat-2 sensor from it's developers.From this document you will get a step by step procedure on how to convert DN values of a set of pixels from a Cartosat-2 satellite image.The formulae that leads to values of bias,scale factor,and solar irradiance are definitely provided.
