.SH DESCRIPTION
\fBr.support\fR 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.
.SS Raster band management
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.
.br
.SH EXAMPLES
These examples are based on the North Carolina dataset, more specifically the \fIlanduse\fR raster map.
Copy the landuse map to the current mapset
.br
.nf
\fC
g.copy raster=landuse,my_landuse
\fR
.fi
.SS Update statistics
.br
.nf
\fC
r.support \-s map=my_landuse

.fi
.SS Update Title
.br
.nf
\fC
r.support map=my_landuse title=\(dqLanduse copied\(dq
\fR
.fi
.SS Append to History Metadata
.br
.nf
\fC
r.support map=my_landuse history=\(dqCopied from PERMANENT mapset\(dq
\fR
.fi
.SS Update Units Display
.br
.nf
\fC
r.support map=my_landuse units=meter
\fR
.fi
.SS Set semantic label
Note: landuse map doesn\(cqt confirm to CORINE specification. This is an example only.
.br
.nf
\fC
r.support map=my_landuse semantic_label=CORINE_LULC
\fR
.fi
.SH NOTES
If metadata options such as \fBtitle\fR or \fBhistory\fR are given the
module will run  non\-interactively. If only the map name is given
\fIr.support\fR will run interactively within a terminal shell and the
user with be prompted for input.
.PP
Freeform metadata information is stored in a \(dqhist\(dq file which may be
appended to by using the \fBhistory\fR 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.
