[GRASS-user] does i.sentinel.mask only work with output from i.sentinel.preproc?

[Margherita Di Leo]

Hi,

I'm trying to use i.sentinel.mask on a Sentinel2 L2A.

i.sentinel.mask -r input_file=input_cloud_mask.txt cloud_mask=cloud
shadow_mask=shadow cloud_threshold=25000 shadow_threshold=5000
mtd_file=MTD_TL.xml

The  input_cloud_mask.txt file:

blue=L2A_T34UGD_20161206T094402_B02_10m
green=L2A_T34UGD_20161206T094402_B03_10m
red=L2A_T34UGD_20161206T094402_B04_10m
swir11=L2A_T34UGD_20161206T094402_B11_20m
nir=L2A_T34UGD_20161206T094402_B08_10m
swir12=L2A_T34UGD_20161206T094402_B12_20m
nir8a=L2A_T34UGD_20161206T094402_B8A_20m

I get the following error:

WARNING: Any rescale factor has been applied
ERROR: Raster maps must be DCELL o FCELL

I didn't use i.sentinel.preproc because our colleagues already preprocess
L1C images and provide L2A, but AFAIU here I should start from a L1C image,
and preprocess it with i.sentinel.preproc otherwise I can't apply
i.sentinel.mask, is this correct?

Thanks for any pointers
Regards,
