This feature has been labeled as deprecated. The recommended replacement is: marker=* + utility=*.
The reason is documented in Deprecated features. You are still free to continue to use or interpret this tag as you see fit since OpenStreetMap does not have “banned features”.
Under no circumstances should you (semi-)automatically change “deprecated” tags to something else in the database on a large scale without conforming to the automated edits code of conduct. Any such change will be reverted.

A tag used for man_made=pipeline markers, be it a separate pole sticking out of the ground, or a wall marker describing the distance to a pipeline valve or other feature. Used on nodes.

Note that the markers describe the distance/location of a nearby access port and do not necessarily sit right on top of the feature. A pipeline OSM way may therefore have its nodes at these access ports rather than at the markers.

Tags

• ref=* unique identifier of the marker, usually consecutively numbered
• support=pole/wall_mounted/ground/pedestal describes where the marker plate is mounted. Use wall_mounted also if the marker is mounted on a fence.
• cover=cone/fin/roof specifies the shape of the cover on top of a pole.
• operator=* (optional)
• phone=* (optional)
• emergency_phone=* (optional)
• substance=* the type of medium transported by the pipeline.
• pipeline:ref=* since markers are often located in close vicinity to, but not directly on top of a pipeline, pipeline:ref=* links the marker to the pipeline. Use the same value as in the pipelines ref=* tag. If the marker is defined in a node of the way, it is not necessary to specify this tag.
• valve:ref=* if the marker points to a valve which is located at a distance, valve:ref=* links the marker to the valve. Use the same value as in the valves ref=* tag.
• measurement=* if the marker has some kind of measuring box/device attached, this tag describes the kind of measurement provided. Use yes if the type of measuring can not be determined.
• position=left;right;distance;heading holds the position information (in meters) as listed on the marker. This position defines a point through which the pipeline is supposed to run. If a value is not specified on the marker plate, do not use this tag. heading is optional. It describes the direction the marker is facing in degrees (0 .. 360). May be measured by a compass, but is usually also stored as EXIF value in pictures taken by modern smartphones (don't forget to subtract 180°).

left: distance from the marker to the left

right: distance from the marker to the right. Usually, just left OR right is defined.

distance: distance from the marker in direction to the position of the viewer (in front of the marker)

Tag history

• Described as "Values to be replaced" by this proposal with a "New tag(s) to use" of marker=* + utility=* gas/oil
• a contributor pointed out that :

1. this conversion leads to the loss of information that it concerns a pipeline
2. the content information is missing from the original tag and is not a good suggestion for replacement but a suggestion for additional information

• The replacement was therefore changed to marker=yes + subject=pipeline
