NAME

r.out.bin - Exports a GRASS raster to a binary array.

KEYWORDS

raster, export, output

SYNOPSIS

r.out.bin
r.out.bin --help
r.out.bin [-ifhbs] input=string [output=string] [null=float] [bytes=integer] [order=string] [--help] [--verbose] [--quiet] [--ui]

Flags:

-i: Generate integer output
-f: Generate floating-point output
-h: Export array with GMT compatible header
-b: Generate BIL world and header files
-s: Byte swap output
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

input=string [required]: Name of input raster map
output=string: Name for output binary map (use output=- for stdout)
null=float: Value to write out for null
Default: 0
bytes=integer: Number of bytes per cell
Options: 1, 2, 4, 8
order=string: Output byte order
Options: big, little, native, swap
Default: native

DESCRIPTION

The r.out.bin 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.

NOTES

With the -h flag, data can be directly used by GMT as Grid Format 1 (float) or 2 (short). For example:


r.out.bin -h input=grass.raster output=new.grd
grdinfo new.grd=1 (if float)

Exported data can be piped directly into the GMT program xyz2grd.


r.out.bin input=grass.raster output=- | xyz2grd -R....  -ZTLf -

The example uses the GMT program xyz2grd with the -ZTLf flag indicating that a float array was output.

AUTHOR

This program is derived from r.out.ascii with a few modifications.
