Surface reflectance algorithm for Landsat dataset and calculation of indices

Hello Sean, Thanks, I will have a look at the l2gen code. I am using Landsat 5, 7 and 8 and I have already done the conversion from DN to Radiance and from Radiance to ToA reflectance with the formulas I have found in the Dat User's Handbooks from each satellite. If you have used already the l2g...
