NAME
v.to.rast3 - Converts a vector map (only points) into a 3D raster map.
KEYWORDS
vector, volume, conversion
SYNOPSIS
v.to.rast3
v.to.rast3 help
v.to.rast3 input=name layer=string output=name column=name [--overwrite] [--verbose] [--quiet]
Flags:
- --overwrite
- Allow output files to overwrite existing files
- --verbose
- Verbose module output
- --quiet
- Quiet module output
Parameters:
- input=name [required]
- Name of input vector map
- Or data source for direct OGR access
- layer=string [required]
- Layer number or name
- A single vector map can be connected to multiple database tables. This number determines which table to use. When used with direct OGR access this is the layer name.
- Default: 1
- output=name [required]
- Name for output 3D raster map
- column=name [required]
- Name of attribute column (data type must be numeric)
DESCRIPTION
v.to.rast3 converts a GRASS 3D vector point map to a GRASS 3D raster map.
NOTES
When converting from a 3D vector point layer to a 3D raster map
a vector point is converted into a single 3D raster cell (voxel)
representing the location of the vector point. As 3D raster cell
value the database attribute of the vector point is stored with
floating point precision.

This screenshot shows the result of the v.to.rast3 test. Visualized are the cube of the
grass region, the vector points as black dots and the voxel cells as wireframe model. Only cells with
non-null values are shown.
