Landsat DN Band Computations

You can do band computations for new grids, like band ratios and NDVI, using

 

All of these will have correlation coefficents among themselves typically over 0.99.

These all use TOA (top of atmosphere values where the satellite orbits), since we do not currently use an atmospheric correction model.

Corrections use the constants in the metadata file for each scene (https://www.usgs.gov/land-resources/nli/landsat/using-usgs-landsat-level-1-data-product

These are currently not yet implemented for Sentinel-2, but its DN is really a reflectance

Select which you want on the Imagery tab of the options form,

You can create grids with each of the parameters.
