Hi Quinten,
I was able to mask the shaded areas using the TanDEM-X 90 m DEM and the matlab hillshade function: https://de.mathworks.com/matlabcentral/ ... -hillshade
I'm sure there's a more elegant solution, but this does the job for now.
Ciao,
Dan

Hi Quinten,
Any progress on this? I have the Copernicus 30 m DEM in my SNAP auxdata folder, if you need it.
Thanks!

Hi Quinten, Thanks! I am looking into options to mask the shadows. IdePix (SNAP) with the Copernicus 30m Global DEM does a pretty good job at identifying mountain shadows, but I can only apply it to the L1C images. If necessary, I could run IdePix separately and then apply the mountain shadow mask t...

Advice with settings for rhorc
First, thanks very much for developing and supporting this free tool. I am trying to perform atmospheric correction of two Sentinel-2 tiles in a fjord system in Greenland. I would like to work with the Rayleigh-corrected reflectances. I am only able to get acolite to run when I set dsf_path_reflecta...
