DESCRIPTION

r.support allows the user to create and/or edit raster map support information. 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 specfically 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.
