   Parameters:
       map=name[,name,...] [required]
           Name of raster map(s)

       semantic_label=name[,name,...]
           Name of semantic label identifier (example: S2_1)

DESCRIPTION

       r.semantic.label  allows  assigning a semantic label information to a single raster map or
       to a list of specified raster maps.  Semantic  label  can  be  defined  by  semantic_label
       option.  Already  assigned  semantic  label  can be removed from a specified raster map by
       operation=remove. The module also allows  printing  detailed  semantic  label  information
       already assigned to a raster map by operation=print.

       Either a single raster map or a list of raster maps can be given by map option.

NOTES

       Note that only raster maps from the current mapsets can be modified.

       For  more  information  about  semantic  label  concept  and  supported  sensors  (generic
       multispectral system, Landsat-5, Landsat-7, Landsat-8, Sentinel-2) see the  i.band.library
       module.

       Semantic  labels are supported by temporal GRASS modules. Name of STRDS can be extended by
       band identifier in order to filter  the  result  by  a  semantic  label.  See  t.register,
       t.rast.list, t.info and t.rast.mapcalc modules for examples.

EXAMPLES

   Assign semantic label to a single raster map
       r.semantic.label map=T33UVR_20180506T100031_B01 semantic_label=S2_1

   Assign semantic label to a list of raster maps
       r.semantic.label map=T33UVR_20180506T100031_B01,T33UVR_20180521T100029_B01 semantic_label=S2_1,S2_1

   Assign different semantic labels to a list of raster maps
       r.semantic.label map=T33UVR_20180506T100031_B01,T33UVR_20180506T100031_B02 semantic_label=S2_1,S2_2

   Remove semantic label from a list of raster maps
       r.semantic.label map=T33UVR_20180506T100031_B01,T33UVR_20180506T100031_B02 operation=remove

   Print semantic label information about single raster map
       r.semantic.label map=T33UVR_20180506T100031_B01 operation=print

   Print extended semantic label information for a list of raster map
       r.semantic.label map=T33UVR_20180506T100031_B01,T33UVR_20180506T100031_B02 operation=print

KNOWN ISSUES

       r.semantic.label allows managing semantic labels only related to 2D raster maps.
