DESCRIPTION

80       r.support  allows  the  user  to  create and/or edit raster map support
81       information. Editing of  raster  map  color  tables,  category  labels,
82       header,  history,  and  title is supported. Category labels can also be
83       copied from another raster map.
84

EXAMPLES

86       These examples are based on the North Carolina  dataset,  more  specfi‐
87       cally  the  landuse  raster  map.   Copy the landuse map to the current
88       mapset
89       g.copy raster=landuse,my_landuse
90
91   Update statistics
92       r.support -s map=my_landuse
93
94   Update Title
95       r.support map=my_landuse title="Landuse copied"
96
97   Append to History Metadata
98       r.support map=my_landuse history="Copied from PERMANENT mapset"
99
100   Update Units Display
101       r.support map=my_landuse units=meter
102

NOTES

104       If metadata options such as title or history are given the module  will
105       run   non-interactively.  If  only the map name is given r.support will
106       run interactively within a terminal shell and the user with be prompted
107       for input.
108
109       Freeform  metadata  information is stored in a "hist" file which may be
110       appended to by using the history option. Currently this is  limited  to
111       50 lines of text with a maximum line length of 78 characters. Any input
112       larger than this will be wrapped to the next line.  All other  metadata
113       strings available as standard options are limited to 79 characters.
