I am planing to make a comparison of forest cover between 1984 and 2021. I will use Landsat 5 and Landsat 8 images.

Could some recommend any pre process corrections or calibrations for both satellites ?

If I do radiometric calibration and dark objects subtraction for Landsat 8, Should I do the same for Landsat 5?

Or do landsat 5 accept radiometric calibration and dark objects subtraction? Or just a Quick Atmospheric correction can fulfill it ?

Please help.
