The i.sentinel.import module allows importing Sentinel products downloaded by the module.

By default i.sentinel.import imports all Sentinel bands found in input directory by r.import. Note that in the case that spatial reference system of input data differs from GRASS location, the input data are reprojected.

Optionally input data can be linked by r.external when -l is given. Note that linking data requires that input data and GRASS location have the same spatial reference system.

Number of imported Sentinel bands can be optionally reduced by the pattern option. Below an overview of the Sentinel-2 MSI band spatial resolutions:

Spatial resolution [m] S2 Bands
10 B2, B3, B4, B8
20 B5, B6, B7, B8a, B11, B12
60 B1, B9, B10


If -c flag is given, than also cloud mask file is imported as vector map if available. Name of created vector map is determined from input Sentinel product.


At first, print list of raster files to be imported by -p. For each file also projection match with current location is printed including detected input data EPSG code.
i.sentinel.import -p input=data

Import all Sentinel bands found in data directory:
i.sentinel.import input=data
Limit import to only to 4th and 8th bands:
i.sentinel.import input=data pattern='B0(4|8)'
Limit import to only to all bands with 10m resolution (excluding AOT, WVP, ... bands):
i.sentinel.import input=data pattern='B0[2|3|4|8]_10m'
Link data and import also cloud mask file:
i.sentinel.import -l -c input=data
