OSM Tag History
covered
=*
is used to denote whether an object represented by a node, way or area is covered.
For highways and railways this differs from
tunnel
=*
in that
it is usually open at least on one side
. This then implies
covered
yes
Also used in some situations where use of
layer
=*
is not meaningful.

Usage
Use this tag for:
Highways, footways, railways, or waterways that are (even partially) covered by a building or other structure other than where
tunnel
=*
(including
tunnel
building_passage
) applies.
Power lines, water mains, water drains, etc. in a narrow trench, with coverings traversable by traffic (foot, vehicle, or otherwise) and removable for access and maintenance.
Buried objects other than where
location
underground
applies, like an area such as an underground parking lot, a covered reservoir/cistern or even such things as an aquarium (e.g., Kelly Tarlton's, Auckland, NZ), when the covering is not a man-made structure that would allow layer differentiation.
amenity
bicycle_parking
which is protected from rain.
Some mappers use this tag for:
Highways under the area of a
man_made
bridge
. This is controversial, see
Talk:Key:covered
Do
not
use this tag for:
Objects in tunnels (
tunnel
=*
) where layering (
layer
=*
) is established.
Avalanche protectors
tunnel
avalanche_protector
) even where open on one side.
Roof covered bridges (
bridge
covered
).
Where
location
underground
or
location
underwater
applies.
Values
Ways passing
through
buildings should normally have the same (or none) layer as the building.
When used this way the building and the way should have shared nodes at the entry and exit points of the building. The way should be split at the entry and exit nodes and only the part covered by the building should be tagged with covered=yes.
covered
no
Marks that an object is not covered.
covered
yes
For covered objects which are not covered by an arcade or a colonnade. This tag was approved by
proposed features/covered
The following tags are in use, but were not included in the original proposal:
covered
arcade
An arcade is a succession of arches, each counterthrusting the next, supported by columns or piers or a covered walk enclosed by a line of such arches on one or both sides.
Such ways should be tagged with
covered
arcade
. If the arcade is part of a building, the building and the way share the same node at the entry and exit points. The way is split at the entry and exit nodes and only the part covered by the building is tagged with
covered
arcade
The layer has to be the same as the building. So if the building doesn't have a layer tag, the way doesn't need one either. Use
arcade:left
open
or
arcade:right
open
to define which side of the way is open.
When
arcade
should not be used:
It is not meant to be used for indoor mapping. The wall on one side is considered as an outer wall which can have entrances that lead into the building. For indoor mapping
indoor
yes
can be used.
Also it is not meant to be used for simple roof overhangs or
blind arcades
A typical arcade in South Tyrol
covered
colonnade
Similar to arcades, but differ architecturally, a colonnade denotes a long sequence of columns joined by their entablature, often free-standing, or part of a building.
Such ways should be tagged with
covered
colonnade
. If part of a building, the building and the way share the same node at the entry and exit points. The way is split at the entry and exit nodes and only the part covered by the building is tagged with
covered
colonnade
The layer has to be the same as the building. So if the building doesn't have a layer tag, the way doesn't need one either. Use
colonnade:left
open
or
colonnade:right
open
to define which side of the way is open.
When
colonnade
should not be used:
It is not meant to be used for indoor mapping. The wall on one side is considered as an outer wall which can have entrances that lead into the building. For indoor mapping
indoor
yes
can be used.
Also it is not meant to be used for simple roof overhangs. (In this case, "
porch
" might be more appropriate).
Kanslihusets arkad
(misleading name; it's a
colonnade
, not an arcade.)
The colonnade of famous Baroque architect Gian Lorenzo Bernini in front of St Peter's in Rome
covered
partial
Some mappers use this tag to show that an object is only partially covered (e.g. by a roof), as
covered
yes
would mean it is full-covered or people interpret this as being full-covered.
covered
partial
sometimes applies to railway and other public transport platforms (e.g.
railway
platform
), where the platform should usually be one object (one feature, one OSM element), and when people then want to use
covered
=*
to show that is covered in part. But if so, consider drawing another way for where the roof is and add
building
roof
and the suitable
layer
=*
tag for the roof, at least additionally, or even instead.
covered
booth
This tagging is used for public telephones (
amenity
telephone
) which are full-covered by a phone booth with door. The tag covered=booth was chosen first to make it possible to differentiate between a full-cover booth and a roof (which would be tagged with
covered
yes
) and second because the tag
shelter
yes
does not have the same meaning.
shelter
yes
on an object shows that there is an
amenity
shelter
at this object and this is not the same as a phone booth. A phone booth is intended to cover the person who is using the phone, but it's not a shelter where several people can wait on a bus or stay protecting them from rain
comfortable
Please note that covered=booth is the above-tag for the key
booth
=*
, which specifies the type of booth.
For tagging a phone booth which is used as a public bookcase, please use
amenity
public_bookcase
public_bookcase:type
phone_box
booth
instead. covered=booth is not so appropriate for these, because this tag describes how a feature is covered, not the feature itself (which would be a public bookcase then). Former phone booths which are public bookcases now are the one exception where
booth
=*
can be added without adding
covered
booth
before.
Examples
Additional attributes
maxheight
=*
may also be associated with the covered way or area to indicate clearance.
Rationale
This section changed since the approval of this feature as a result of refinement of the definition of the
layer
=*
tag.
While using the layer or level tags is the conventional means of showing that one object is above another there are numerous situations where these tags are inappropriate and can be misleading in the context of the subsystem being mapped.
For example, when a building has a way passing through it, the building and the way through it can not be assigned distinct layers. In this situation
tunnel
building_passage
is used when the way has outer building walls to all sides. The tag
covered
=*
is used when the way is open on at least one side.
A tag
covered
=*
on the way will make routing more efficient in cases where, for example, a route to avoid the natural elements is desired, or a route to covered parking or to an area for sheltered entry or egress into a vehicle is desired.
In other cases objects can be assigned a distinct layer but can not be represented by either a bridge, tunnel, or indoor mapping - in those cases
covered
=*
provides a simple method to express such situations.
Another use case; some objects such as underground parking garages and reservoirs are covered by an object that would not be mapped separately.
