v.extrude - Extrudes flat vector object to 3D with defined height

KEYWORDS

vector

SYNOPSIS

v.extrude
v.extrude help
v.extrude [-t] input=string output=string [zshift=float] [elevation=string] [height=float] [hcolumn=string] [type=string[,string,...]] [layer=integer] [--overwrite]

Flags:

-t
Trace elevation
--overwrite
Force overwrite of output files

Parameters:

input=string
Name of input 2D vector map
output=string
Name of resulting 3D vector map
zshift=float
Shifting value for z coordinates
Default: 0
elevation=string
Elevation raster for height extraction
height=float
Fixed height for 3D vector objects
hcolumn=string
Column of attribute table with object heights
type=string[,string,...]
Type
Options: line,boundary,area
Default: line,boundary,area
layer=integer
Layer number
Default: 1

DESCRIPTION

v.extrude makes 3D blocks or just walls from 2D polygons or lines.

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
