           Force launching GUI dialog

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

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

           Default: add

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.
