r3.to.rast(1grass)


NAME

   r3.to.rast  - Converts 3D raster maps to 2D raster maps

KEYWORDS

   raster3d, conversion, raster, voxel

SYNOPSIS

   r3.to.rast
   r3.to.rast --help
   r3.to.rast  [-mr]  input=string  output=string  [--overwrite]  [--help]
   [--verbose]  [--quiet]  [--ui]

   Flags:
   -m
       Use 3D raster mask (if exists) with input map

   -r
       Use the same resolution as the input  3D  raster  map  for  the  2D
       output maps, independent of the current region settings

   --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=string [required]
       3D raster map(s) to be converted to 2D raster slices

   output=string [required]
       Basename for resultant raster slice maps

DESCRIPTION

   Converts  one  3D  raster  map  into several 2D raster maps (depends on
   depths).  If the 2D and  3D  region  settings  are  different,  the  3D
   resolution  will  be  adjusted to the 2D resolution (the depths are not
   touched).  The user can force r3.to.rast to use the  2D  resolution  of
   the  input  3D  raster  map for the output maps, independently from the
   current region settings.

   How r3.to.rast works

NOTES

   Every slice of the 3D raster map is copied to one 2D  raster  map.  The
   maps  are named like output_slicenumber. Slices are counted from bottom
   to the top, so the bottom slice has number 1.  The number of slices  is
   equal to the number of depths.
