.SH DESCRIPTION
The \fIr.out.bin\fR program exports a GRASS raster map to a binary array
file. Optionally, output can be sent to standard output (stdout) for direct
input (pipe) into other applications. Data is exported according to the
original GRASS raster type (e.g. float). If the "-i" flag is specified, an
integer array is output. The region parameters are printed to stderr.
.SH NOTES
With the \-h flag, data can be directly used by
GMT as Grid Format 1 (float) or 
2 (short). For example:
\fC
.DS
.br
r.out.bin \-h input=grass.raster output=new.grd
.br
grdinfo new.grd=1 (if float)
.br
.DE
\fR
.PP
Exported data can be piped directly into the GMT program xyz2grd.
\fC
.DS
.br
r.out.bin input=grass.raster output=- | xyz2grd -R....  -ZTLf -
.br
.DE
\fR
The example uses the GMT program xyz2grd with the -ZTLf flag indicating that
a float array was output.
