r.to.rast3(1)

NAME
r.to.rast3 - Converts 2D raster map slices to one 3D raster volume map.

KEYWORDS
raster, conversion, voxel

SYNOPSIS
r.to.rast3
r.to.rast3 --help
r.to.rast3 [-m] input=name[,name,...] output=name [tilesize=integer] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

  Flags:

-m
    Use 3D raster mask (if exists) with output map

--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[,name,...] [required]
    2D raster maps which represent the slices

output=name [required]
    Name for output 3D raster map

tilesize=integer
    The maximum tile size in kilo bytes. Default is 32KB.
    Default: 32

DESCRIPTION
Converts 2D raster map(s) into one raster3D map. It is important to properly set the 3D region settings, especially number or layers and depth of layers. If the 2D and 3D region settings are different, the 2D resolution will be adjusted to the 3D resolution.
How r.to.rast3 works

NOTES
Every 2D raster map is copied as one slice to the raster3D map. Slices are counted from bottom to the top, so the bottom slice has to be number 1.
If less number of 2D raster maps are provided than defined depths, the last given 2D map is used to fill up the remaining raster3D slices to the top.

EXAMPLES

  EXAMPLE 1
This example shows how to convert 6 maps into one 3D map with 6 layers.

# Mapset data in Location slovakia3d
g.region raster=prec_1,prec_2,prec_3,prec_4,prec_5,prec_6 -p
g.region b=0 t=600 tbres=100 res3=100 -p3
r.to.rast3 input=prec_1,prec_2,prec_3,prec_4,prec_5,prec_6 output=new_3dmap

  EXAMPLE 2
This example shows how to convert 3 maps into one 3D map with 6 layers.

# Mapset data in Location slovakia3d
g.region b=0 t=600 tbres=100 res3=100 -p3
r.to.rast3 input=prec_1,prec_2,prec_3 output=new_3dmap
