raster, raster3d, voxel, conversionSYNOPSIS
r.to.rast3elevr.to.rast3elev help
r.to.rast3elev [-ulm] input=name[,name,...] elevation=name[,name,...] output=name [upper=float] [lower=float] [--overwrite] [--verbose] [--quiet]
Flags:
- -u
Use the input map values to fill the upper cells- -l
Use the input map values to fill the lower cells- -m
Use G3D mask (if exists) with input map- --overwrite
Allow output files to overwrite existing files- --verbose
Verbose module output- --quiet
Quiet module output
Parameters:
- input=name[,name,...]
Name of input raster map(s)- elevation=name[,name,...]
Name of elevation raster map(s)- output=name
Name for output raster3d map- upper=float
The value to fill the upper cells, default is null- lower=float
The value to fill the lower cells, default is null
DESCRIPTION
Creates a 3D volume map based on 2D elevation and value raster maps. If the 2d and 3d region settings are different, the 2d resolution will be adjust to the 3d resolution.|
How r.to.rast3elev works
NOTES
The hight of the 2D elevation maps will be used to verify the position within the 3D region. If the cell value of the elevation raster maps is located within the 3d region, the cell value of the appropriate 2D input raster maps will be written to the associated 3d cell. There are flags and options to fill the upper and lower 3D cells with a specific value, or the input raster maps values.Example
Simple Spearfish exampleg.region -d
g.region res=200 res3=200 t=5000 b=0 tbres=100
# Write the values of raster map soils based on the elevation of elevation.10m
# to the 3D map volev
r.elev.to.rast3 in=soils elev=elevation.10m out=volev
# Write the values of map soils based on the elevation of elevation.10m
# to the 3D map volev_l and fill the lower cells with the soils map values
r.elev.to.rast3 in=soils elev=elevation.10m out=volev_l -l
# Write the values of map soils based on the elevation of elevation.10m
# to the 3D map volev_u and fill the upper cells with the soils map values
r.elev.to.rast3 in=soils elev=elevation.10m out=volev_u -u
