DESCRIPTION

44       Creates  a  3D  volume map based on 2D elevation and value raster maps.
45       If the 2d and 3d region settings are different, the 2d resolution  will
46       be adjust to the 3d resolution.  | How r.to.rast3elev works
47

NOTES

49       The  hight of the 2D elevation maps will be used to verify the position
50       within the 3D region. If the cell value of the elevation raster maps is
51       located  within  the  3d  region,  the cell value of the appropriate 2D
52       input raster maps will be written to the associated 3d cell.  There are
53       flags  and options to fill the upper and lower 3D cells with a specific
54       value, or the input raster maps values.

Example

57       Simple Spearfish example
58       g.region -d
59       g.region res=200 res3=200 t=5000 b=0 tbres=100
60       # Write the values of raster map soils based on the elevation of eleva‐
61       tion.10m
62       # to the 3D map volev
63       r.elev.to.rast3 in=soils elev=elevation.10m out=volev
64       # Write the values of map soils based on the elevation of elevation.10m
65       #  to  the  3D  map volev_l and fill the lower cells with the soils map
66       values
67       r.elev.to.rast3 in=soils elev=elevation.10m out=volev_l -l
68       # Write the values of map soils based on the elevation of elevation.10m
69       # to the 3D map volev_u and fill the upper cells  with  the  soils  map
70       values
71       r.elev.to.rast3 in=soils elev=elevation.10m out=volev_u -u
