SNAP LAI Calculate on THEIA S2A Images

Optical Toolbox

Dear @hassan,

I could successfully process the Sentinel-2 Level-2A MUSCATE product downloaded from Theia using the Biophysical processor.
The procedure that I have found to work is:

  • Open the “*_MTD_ALL.xml” file inside the downloaded MUSCATE product in SNAP
  • Resample data to a common spatial resolution using the standard Resampling operator under “Raster --> Geometric Operations --> Resampling” (the use of the S2 Resampling is still not supported for the MUSCATE products as reported here SNAP plugin to import S2 L2A products from Theia)
  • Optionally subset the product keeping either the ‘surface reflectance’ or the ‘flat reflectance’ bands (or create the subset using BandMaths and specifying properly the band names (e.g. B2, B8A, etc) and the wavelengths to the resulting image).
  • Run the Biophysical processor

Hope this procedure works also in your case.

Federico
