DESCRIPTION

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
92   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.
98

EXAMPLES

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
105   Update statistics
106       r.support -s map=my_landuse
107
108   Update Title
109       r.support map=my_landuse title="Landuse copied"
110
111   Append to History Metadata
112       r.support map=my_landuse history="Copied from PERMANENT mapset"
113
114   Update Units Display
115       r.support map=my_landuse units=meter
116
117   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

NOTES

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
128       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.
