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.

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

r.semantic.label   -  Manages  semantic label information assigned to a single raster map or to a list of
       raster maps.

       Note that onlyrastermapsfromthecurrentmapsets 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.
