Table of contents


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).


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.
