Atmospheric Toolbox

DLL files can't be found

I can open a Sentinel file but wplot() is not working. I installed Visan as described in the manual (

conda create -n visan
conda activate visan
conda install -c stcorp-forge -c conda-forge visan=4.2

It looks like required DLL files can’t be found.

Could you please help me with that. Thanks in advance.

I can confirm that VISAN is indeed not working when performing a clean install.

It seems that this is due to an updated version of the ‘proj’ library (conda installations now come with version 8 instead of version 7). We are working on fix.

In the mean time you could try installing visan by adding a proj<8 argument to your conda install command.
