DESCRIPTION
r.support allows the user to create and/or edit raster map support in-
formation. Editing of raster map color tables, category labels, header,
history, and title is supported. Category labels can also be copied
from another raster map.
EXAMPLES
These examples are based on the North Carolina dataset, more specfi-
cally the landuse raster map. Copy the landuse map to the current
mapset
g.copy raster=landuse,my_landuse
Update statistics
r.support -s map=my_landuse
Update Title
r.support map=my_landuse title="Landuse copied"
Append to History Metadata
r.support map=my_landuse history="Copied from PERMANENT mapset"
Update Units Display
r.support map=my_landuse units=meter
NOTES
If metadata options such as title or history are given the module will
run non-interactively. If only the map name is given r.support will
run interactively within a terminal shell and the user with be prompted
for input.
Freeform metadata information is stored in a "hist" file which may be
appended to by using the history option. Currently this is limited to
50 lines of text with a maximum line length of 78 characters. Any input
larger than this will be wrapped to the next line. All other metadata
strings available as standard options are limited to 79 characters.
