NAME
v.extrudeDESCRIPTION
v.extrude makes 3D blocks or just walls from 2D polygons or lines.Selected Flags and Parameters
- -t
- If defined, roof and walls will follow ("trace") the elevation by using individual elevation values for the vertices and nodes at bottom. This should be useful for models of large objects (forest stands).
- zshift
- Vertical shift of vector data on top of values extracted from elevation model/defined fixed height.
- elevation
- Raster elevation map to put on the vector 3D objects.
- height
- Global height of vector 3D objects. If not specified, the module
- expects the hcolumn parameter.
- hcolumn
- Column from attribute table, in which the attribute of object
- height is stored (must be of int, double, or varchar type).
EXAMPLES
3D houses with fixed height
v.extrude input=houses output=houses3D height=5
3D houses with individual height
v.extrude -t input=houses output=houses3D elevation=dem hcolumn=height
