Is there a way to make Level-2 Landsat images (e.g. Landsat-5 images ordered from EarthExplorer) comparable with Level-2A Sentinel-2 images?
The objective is to calculate water or vegetation indices (NDVI or NDWI) from both and be able to accurately evaluate the change between the two, since they were not acquired on the same year obviously. The Sentinel-2 Level-2A images were either downloaded from Sentinel Hub or atmospherically corrected with Sen2cor.
While both of them are atmospherically corrected, the pixels values I find in their image bands are on a completely different order of magnitude.
