Usage of Biophysical Operator for Landsat-8

Optical Toolbox
#1

Hello,
the Biophysical operator requires atmospherically corrected surface reflectances, so L2 data.
When using the Landsat-8 L2 data from Collection 2 the required geometry bands are missing.
So, this operator does not work out of the box. How shall the viewing geometry be retrieved? Shall they be copied from the corresponding L1 data product and renamed to view_zenith_mean, sun_zenith, sun_azimuth, view_azimuth_mean) or is there another suggested way?
I think it would be good to mention this on the help pages.

Ciao

The solution is, indeed, to copy the four bands from the L1 product. For these bands, the DN values are scaled by 100, so the Band Maths operator will have to be used to multiply by 0.01.
We’ll update the help of the Biophysical Processor LANDSAT8.
