## NAME

r3.out.bin - Exports a GRASS 3D raster map to a binary array.

## KEYWORDS

raster3d, export, voxel

## SYNOPSIS

r3.out.bin
r3.out.bin --help
r3.out.bin [-rdi] input=name output=name [null=float] bytes=integer [order=string] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

### Flags:

-r
  Switch the row order in output from north->south to south->north
-d
  Switch the depth order in output from bottom->top to top->bottom
-i
  Write data as integer
--overwrite
  Allow output files to overwrite existing files
--help
  Print usage summary
--verbose
  Verbose module output
--quiet
  Quiet module output
--ui
  Force launching GUI dialog

### Parameters:

input=name [required]
  Name of input 3D raster map
output=name [required]
  Name for output file
null=float
  Value to write out for null
  Default: 0
bytes=integer [required]
  Number of bytes per cell in binary file
  Options: 1, 2, 4, 8
order=string
  Output byte order
  Options: big, little, native, swap
  Default: native

## DESCRIPTION

The r3.out.bin program exports a GRASS 3D raster map to a binary array file. Optionally, output can be send to standard output (stdout) for direct input (pipe) into other applications. Data is exported according to the original GRASS 3D raster type (float, double).

## NOTES

The write order of the rows (north->south to south->north) and the write order of the depths (bottom->top to top->bottom) can be switched.

The region parameters are printed to stderr when setting the verbose flag. Export of little and big endian byte order is supported.

Have a look at r3.out.ascii manual page that describes the internal layout of the 3D raster maps and the supported row and depth switch options.

## EXAMPLES

Have a look at the examples in r3.in.bin.
