Tagging
Units
The
default unit
is metres. If the height is measured in a different
unit
, the unit abbreviation is appended to the value, separated by a space (except for feet/inch). See the examples below or the
unit specification
article for more information. For height values with decimal places, use the
period character
as decimal separator.
Sources
The source of the height information can be specified by
source:height
=*
The accuracy of the height information can be specified by
height:accuracy
=*
Examples
Here are a few examples of how a height can be tagged.
Height
Tagging
Remark
Four metres
height
Specifying the units is optional for metres, and would look like:
height
4 m
1.35 metres
height
1.35
Use the decimal / full stop / period character as a separator.
7 feet and 4 inches
height
7'4"
Use a typewriter apostrophe character after the feet value and a typewriter double-quote character after the inches value. Spaces are not permitted.
Height of buildings
An example map rendering buildings heights
Use the
maximum
height for buildings, not the
average
height. Specifically, the maximum is the distance between the
top edge of the building
(including the roof, but excluding antennas, spires and other equipment mounted on the roof) and the
lowest point at the bottom
where the building meets the terrain.
Building parts
The height of individual parts of buildings uses the same tag, see the
Simple 3D buildings
specification for more details.
Potential issues
Elevation above mean sea level
The
elevation above mean sea level
for objects in OpenStreetMap is
not
specified using the
height
key. Objects using this type of measurement should use the
ele
=*
key. For example, a mountain peak with the
natural
peak
tag uses the
ele
=*
key to specify the highest point on the peak.
Restricted height
Height restrictions, such as the vertical clearance under a bridge or through a tunnel are not tagged using the height key. Use the
maxheight
=*
key to specify the maximum height allowed, or
maxheight:physical
=*
for the highest physically possible clearance.
Hunting stands in German-speaking countries
As of 2023-07, there are over 3,000
amenity
hunting_stand
that are tagged with
height
full/half/low
. Nearly all of these are in German-speaking countries.
Incorrect values
The following table contains examples of incorrect tags and their correct notation, which are commonly misused.
Incorrect
Explanation
Correct
height=4m
The space between value and unit is missing.
height
or
height
4 m
height=0,8
The comma is used as wrong decimal separator.
height
0.8
or
height
0.8 m
height=11' 4"
There should not be a space between feet and inches.
height
11'4"
