Parameters:
- map=name [required]
- Name of raster map
- title=phrase
- Title for resultant raster map
- history=phrase
- Text to append to the next line of the map's metadata file
- units=string
- Text to use for map data units
- vdatum=string
- Text to use for map vertical datum
- source1=phrase
- Text to use for data source, line 1
- source2=phrase
- Text to use for data source, line 2
- description=phrase
- Text to use for data description or keyword(s)
- raster=string
- Raster map from which to copy category table
- loadhistory=name
- Text file from which to load history
- savehistory=name
- Text file in which to save history
- semantic_label=phrase
- Semantic label e.g. S2_8A
r.support allows the user to create and/or edit raster map support
information. Editing of raster map color tables, category labels, header,
history, semantic label elements and title is supported.
Category labels can also be copied from another raster map.
Raster semantic label concept is similar to dimension name in other GIS and
remote sensing applications. Most common usage will be assigning a
remote sensing platform sensor band ID to the raster, although any
identifier is supported. Raster semantic label is suggested to work with
imagery classification tools.
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
r.support -s map=my_landuse
r.support map=my_landuse title="Landuse copied"
r.support map=my_landuse history="Copied from PERMANENT mapset"
r.support map=my_landuse units=meter
Note: landuse map doesn't confirm to CORINE specification. This is an example only.
r.support map=my_landuse semantic_label=CORINE_LULC
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.
