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.
