## 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.elev.to.rast3 works

## NOTES

The hight of the 2D elevation map will be used to verify the position within the 3D region. If the cell value of the elevation rater map is located within the 3d region, the cell value of the 2D input raster map 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 map value.

## Example

Simple Spearfish example

    g.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
