When I access Earth Explorer, I have the option for downloading images for both Landsat 8 Collection Level-1 and Level-2.
For Level-2 I have a brief description that refers to "Surface Reflectance".
I have some troubles on understanding the procedures for image correction and need the images with less need for corrections (dark object subtraction, surface reflectance, etc.)
I need this data for mining mapping.
What is the advisable Level for download?
