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.
