DESCRIPTION

44       r.semantic.label  allows  assigning  a  semantic label information to a
45       single raster map or to a list of specified raster maps. Semantic label
46       can  be defined by semantic_label option. Already assigned semantic la‐
47       bel can be removed from a specified raster map by operation=remove. The
48       module also allows printing detailed semantic label information already
49       assigned to a raster map by operation=print.
50
51       Either a single raster map or a list of raster maps can be given by map
52       option.
53

NOTES

55       Note that only raster maps from the current mapsets can be modified.
56
57       For more information about semantic label concept and supported sensors
58       (generic multispectral system, Landsat-5,  Landsat-7,  Landsat-8,  Sen‐
59       tinel-2) see the i.band.library module.
60
61       Semantic  labels are supported by temporal GRASS modules. Name of STRDS
62       can be extended by band identifier in order to filter the result  by  a
63       semantic  label. See t.register, t.rast.list, t.info and t.rast.mapcalc
64       modules for examples.

EXAMPLES

67   Assign semantic label to a single raster map
68       r.semantic.label map=T33UVR_20180506T100031_B01 semantic_label=S2_1
69
70   Assign semantic label to a list of raster maps
71       r.semantic.label map=T33UVR_20180506T100031_B01,T33UVR_20180521T100029_B01 semantic_label=S2_1,S2_1
72
73   Assign different semantic labels to a list of raster maps
74       r.semantic.label map=T33UVR_20180506T100031_B01,T33UVR_20180506T100031_B02 semantic_label=S2_1,S2_2
75
76   Remove semantic label from a list of raster maps
77       r.semantic.label map=T33UVR_20180506T100031_B01,T33UVR_20180506T100031_B02 operation=remove
78
79   Print semantic label information about single raster map
80       r.semantic.label map=T33UVR_20180506T100031_B01 operation=print
81
82   Print extended semantic label information for a list of raster map
83       r.semantic.label map=T33UVR_20180506T100031_B01,T33UVR_20180506T100031_B02 operation=print

KNOWN ISSUES

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