Hi Roberta,

What about topographic correction (i.topo.corr [1])?
Should that be run before as well?
I would assume it has some impact on shadow detection in steeper terrain…

Hi all!
The first version of i.sentinel.mask is now available and can be installed from the official svn repository.
i.sentinel.mask is a module for cloud and shadow masks computation and it is the first step of my GSoC project.

Thank you, Roberta. Great job !

Thank you!

One question: ISTR that you mentioned that the input to this module has to be atmospherically corrected images, i.e. land surface reflectance. Is this true ? If yes, then this needs to be mentioned in the man page.

Yes, it's true! I'm going to add it.
