48 Parameters:
50 map=name [required]
51 Name of raster map
52 title=phrase
54 Title for resultant raster map
55 history=phrase

73 raster=string
75 Raster map from which to copy category table
76 loadhistory=name
78 Text file from which to load history
79 savehistory=name
81 Text file in which to save history
82 semantic_label=phrase
84 Semantic label e.g. S2_8A
85
87 r.support allows the user to create and/or edit raster map support in‐
88 formation. Editing of raster map color tables, category labels, header,
89 history, semantic label elements and title is supported. Category la‐
90 bels can also be copied from another raster map.
91 Raster band management
93 Raster semantic label concept is similar to dimension name in other GIS
94 and remote sensing applications. Most common usage will be assigning a
95 remote sensing platform sensor band ID to the raster, although any
96 identifier is supported. Raster semantic label is suggested to work
97 with imagery classification tools.

100 These examples are based on the North Carolina dataset, more specfi‐
101 cally the landuse raster map. Copy the landuse map to the current
102 mapset
103 g.copy raster=landuse,my_landuse
104 Update statistics
106 r.support -s map=my_landuse
107 Update Title
109 r.support map=my_landuse title="Landuse copied"
110 Append to History Metadata
112 r.support map=my_landuse history="Copied from PERMANENT mapset"
113 Update Units Display
115 r.support map=my_landuse units=meter
116 Set semantic label
118 Note: landuse map doesn’t confirm to CORINE specification. This is an
119 example only.
120 r.support map=my_landuse semantic_label=CORINE_LULC
121
123 If metadata options such as title or history are given the module will
124 run non-interactively. If only the map name is given r.support will
125 run interactively within a terminal shell and the user with be prompted
126 for input.
127 Freeform metadata information is stored in a "hist" file which may be
129 appended to by using the history option. Currently this is limited to
130 50 lines of text with a maximum line length of 78 characters. Any input
131 larger than this will be wrapped to the next line. All other metadata
132 strings available as standard options are limited to 79 characters.
