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.
