DESCRIPTION

55       Creates a 3D volume map based on 2D elevation and  value  raster  maps.
56       If  the 2d and 3d region settings are different, the 2d resolution will
57       be adjust to the 3d resolution.

NOTES

61       The hight of the 2D elevation maps will be used to verify the  position
62       within the 3D region. If the cell value of the elevation raster maps is
63       located within the 3d region, the cell  value  of  the  appropriate  2D
64       input raster maps will be written to the associated 3d cell.  There are
65       flags and options to fill the upper and lower 3D cells with a  specific
66       value, or the input raster maps values.

Example

69       Simple Spearfish example
70       g.region -d
71       g.region res=200 res3=200 t=5000 b=0 tbres=100
72       # Write the values of raster map soils based on the elevation of eleva‐
73       tion.10m
74       # to the 3D map volev
75       r.elev.to.rast3 in=soils elev=elevation.10m out=volev
76       # Write the values of map soils based on the elevation of elevation.10m
77       # to the 3D map volev_l and fill the lower cells  with  the  soils  map
78       values
79       r.elev.to.rast3 in=soils elev=elevation.10m out=volev_l -l
80       # Write the values of map soils based on the elevation of elevation.10m
81       #  to  the  3D  map volev_u and fill the upper cells with the soils map
82       values
83       r.elev.to.rast3 in=soils elev=elevation.10m out=volev_u -u
