The tag barrier=wall is used to map a wall: a freestanding structure, designed to restrict or prevent movement across a boundary, typically made from solid brick, concrete or rocks, and almost always built so that it is opaque (cannot be seen through).
Also see barrier=fence for fences, barrier=retaining_wall for retaining walls, and barrier=city_wall for town walls.
How to map
Create a line (way) and add the tag barrier=wall
Additional tags
- height=* is used to specify how tall the wall is.
- width=* is used to specify the thickness of the wall. Alternatively, use est_width=* to specify approximately how thick the wall is.
- material=* is used to define the material the wall is constructed of: stone, brick, concrete, wood, etc.
- colour=* is used to define the colour of the wall
For historic walls the tag historic=yes can be used. If it is under preservation see heritage=*.
Mapping as an area
It is also possible to map a wall as an area . Then draw the basic area of the wall and add area=yes.
Further tagging
There are situations a wall is on top of a building or another wall - e.g. noise protection wall on top of a building. Then use key min_height=* for the start height of the wall.
Wall details
The tag wall=* can be used to provide more detailed information about the wall. The value should indicate the principle feature of the wall, which might be the type, purpose, or building material of the wall, as follows:
