Rationale

This proposal adds additional tags to man_made=pipeline and pipeline=marker and describes tags which are in common use, but not yet officially listed in the wiki. The purpose of the additional tags is a more detailed description of these objects and to allow better rendering, i.e. with Maperitive. Also, a new tag for the description of facilities is proposed.

Tagging

Pipelines

The following tags are used in combination with man_made=pipeline:

• name=* the official name of the pipeline

• ref=* use this tag to specify a short, unique identifier for the pipeline. this value is used to logically link pipelines and markers together. usually, marker plates already contain such a unique identifier.

• location=* the location of the pipeline:

List of possible location=* values

Key	Value	Description
location	underground	for pipelines under ground, not visible on the surface
	overground	for pipelines over ground, located close to the surface, not allowing a person or vehicle to pass underneath.
	overhead	for pipelines over ground, located at a height allowing persons or vehicles to pass underneath. use other tags like maxheight=* if applicable. Where the overhead pipeline might affect commercial shipping (crossing a navigational canal or river), consider the use of seamark:type=pipeline_overhead
	underwater	for pipelines running below the surface of land-based bodies of water, like lakes or rivers. for pipelines at sea, use the Seamark tagging scheme.

combine with layer=* if applicable.

• diameter=* specifies the nominal diameter of the pipeline, in millimeters.

• pressure=* specifies the nominal pressure within the pipeline, in bar.

• count=* By design, some media require a pair (or more) of parallel pipelines, i.e. forward and return flow for heat pipelines. This tag specifies the number of pipelines running in parallel. Use this tag only if all pipelines run in parallel and have the same properties, like e.g. diameter. Otherwise, draw a separate way for each pipeline.

• inspection_gauge=yes if the pipeline features a sender or receiver for an inspection gauge, use this tag on the section of the pipeline way where the sender/receiver is located.

• place:origin=* specifies the place=* (town, city, ...) where the pipeline begins. If applicable, use the name as specified in the place=*'s name=* tag.

• place:destination=* specifies the place where the pipeline ends.

• capacity=* specifies the capacity of the pipeline. free text, only for information, since the unit commonly used usually depends on the medium. i.e. barrels/day, m³/h, l/s

• flow_direction=forward/backward/both use both to indicate that the medium within the pipeline may flow in both directions (loop configuration). use forward if the flow is in the direction of the pipeline way, backward otherwise.

• substance=* the substance transported within the pipeline. see Proposed_features/PipelineExtension#Commonly_Used_Substances

• usage=* closer classification of the network this pipeline belongs to:

List of possible usage=* values

Key	Value	Description
usage	flowline	pipelines delivering the medium from the well in the ground to the nearest field gathering station substation=field_gathering
	gathering	pipelines transporting the medium from gathering stations to the central procressing station substation=central_processing
	injection	pipelines on oil & gas fields used to pump gas or water down the well to increase reservoir pressure
	flare_header	pipelines transporting gas to a flare stack
	export	pipelines transporting the medium from a field's central processing station to a pumping / compressor station along the main transmission network.
	transmission	pipelines, usually of large diameter and high pressure, transporting the medium over long distances.
	facility	pipeline network within a refinery or surrounding a compressor station or part of some other industrial facility
	distribution	network of pipes delivering the medium (usually from a substation=distribution) to customers (i.e. households), usually in municipalities

the following tags are used on nodes of the pipeline:

• pipeline=marker if the marker plate contains no position=* information, it is assumed that it is positioned directly above the pipeline. in this case, tag the appropriate node on the pipeline as pipeline=marker (see below)

• pipeline=valve describes a valve (see below)

• pipeline=measurement describes a measuring device (measuring point)

• depth=* the vertical distance from the pipeline to the surface of the ground or sea, in meters.

Pipelines at sea

use the Seamark tagging scheme for pipelines and installations at sea (over or under water), especially the CATPIP related ones. The transition between the OSM standard and the Seamark schemes takes place where the pipeline enters / leaves the sea.

This is also applicable for pipeline installations on land, which may affect commercial shipping (i.e. pipelines over canals etc.)

Markers

The following tags should be used in combination with pipeline=marker:

• 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 pipeline:ref=*.

• valve:ref=* if the marker points to a valve which is located at a distance, valve:ref=* links the marker to the pipeline. use the same value as in the valves ref=* tag.

• 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. (see also amenity=clock)

• cover=cone/fin/roof specifies the shape of the cover on top of a pole.

• 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. (see below)

• 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)

• substance=* the type of medium transported by the pipeline. see Proposed_features/PipelineExtension#Commonly_Used_Substances

depreciated tags

• diameter=* Reason: the diameter is a property of the pipeline and not the marker.

Valves

valves are elements located on the pipeline to control the flow of the medium.

pipeline=valve defines a valve to open or close the connection between two pipelines.

ref=* identifier of the valve (optional)

if the kind of valve is known, use the following subtags to give more detailed information:

List of possible valve=* values

Key	Value	Description	applicable substance=*
valve	blowout	outlet port to release pressure or vent lying in front of a line segment with a valve (both usually under cover)	gas
	air	air relieve valve to release air from the pipeline into the open	gas, water
	fire	in the case of a fire emergency, operated by hand to stop the flow of the medium	gas
	main	to open or close the connection between two pipelines. other than a normal valve, this valve is used to disconnect whole districts or streets.	gas, water

to find out how the type of valve is defined on markers, see HinweisschilderRohrleitungen (for Austria and Germany)

depreciated tags

type=* Reason: already a property of the pipeline (now: substance)

operator=* Reason: already a property of the pipeline. unlikely that one or more valves is operated by a different operator

position=* Reason: the distance from the marker to the valve is described on the marker, not the other way round.

Facilities, Substations

Long distance pipelines usually need additional facilities, i.e. for distribution, compression, flow control (valves) etc. Since these facilities are only used in connection with pipelines, it is suggested to describe them as follows:

(on areas or buildings)

• pipeline=substation defines the area as a facility where the flow of the medium inside the pipeline is controlled and/or altered.

• substation=*describes how the medium is processed. If unknown, do not specify this tag.

Tag	Note
substation=compression	A substation which main purpose is to increase the pressure of the medium inside the pipeline.
substation=distribution	A substation whose main purpose is to distribute the medium from one pipeline to other (minor) pipelines (or vice versa)
substation=measurement	A substation whose main purpose is the gathering of various measurements of a pipeline.
substation=valve	(Usually) A building where the flow of the medium in major (big) pipelines can be stopped by usage of one ore more big valves. Also used to divide a long pipeline into shorter segments. For a single valve on a pipeline, use pipeline=valve on the appropriate node on the pipeline.
substation=valve_group	An area on the ground containing a number of valves. For a building, use substation=distribution or substation=valve
substation=inspection_gauge	An area on the ground whose only feature is a sender/receiver for a pipeline inspection gauge. If a substation of a different kind also features an inspection gauge, use pipeline:inspection_gauge=yes
substation=field_gathering	A facility on an oil/gas field that receives the medium via smaller pipelines directly from the well. The purpose of this substation is to concentrate many smaller feeds into a single, larger one.

Substations are often built in the form of small, industrial-style buildings, but may also be large processing plants.

• pipeline:inspection_gauge=yes use this tag if the facility features a sender or receiver for a pipeline inspection gauge (see Wikipedia:Pigging) If the sender/receiver can definitely be attributed to a pipeline, use inspection_gauge=yes on the appropriate section of pipeline (see above)

• substance=* the substance processed in this substation. usually the same as transported in the pipeline. see Proposed_features/PipelineExtension#Commonly_Used_Substances

Measurements

measurement=* gives a description of the measurements taken in from pipelines:

pipeline=substation If the main purpose of the substation is the gathering of measurements, use it in combination with substation=measurement

Tag a node on the pipeline if the measuring device is located directly on the pipeline.

Use in combination with pipeline=marker if the measuring device is located on a marker.

List of possible measurement=* values

Key	Value	Description	applicable usage=*
measurement	pressure	measuring of the pressure within the pipeline	gas, water, oil
	corrosion	measuring of corrosion related values	gas, oil
	odor	measuring of the density of fragrance (used in gas pipelines to detect leaks by smell)	gas
	inspection_gauge	used to detect the presence of a pipeline inspection gauge	gas, oil
	cable	cable or socket for connecting external measuring equipment	gas, oil

to find out how the type of measurement is defined on markers, see HinweisschilderRohrleitungen (for Austria and Germany)

Commonly Used Substances

The following values are used in the substance=* tag to describe the medium transported in pipelines.

Key	Value	Description	Proposed rendering color
substance	water	fresh water for drinking purposes	blue
	gas	natural gas	orange
	lng	liquified natural gas	different orange
	cng	compressed natural gas	different orange
	oil	unrefined petroleum, as pumped out of the ground	dark brown
	multiphase	combination of gas, oil and water; usually in pipelines running from the wellhead to the processing facility
	butane	butane
	propane	propane
	methane	methane
	propylene	propylene
	ethylene	ethylene
	hydrocarbons	a generic tag that can be used if the exact substance in the pipeline is not known
	chemicals	a generic tag that can be used if the specific chemical in the pipeline is not known
	fuel	gasoline, ready to be used in combustion engines etc.
	cable	cables & cable ducts for electricity, telecom etc.
	heat	medium used to transport heat, mainly to domestic homes	red
	slurry	fluid mixture of a pulverized solid with a liquid, for easy transport
	sewage	sewage	brown
	penstock	water as used for the generation of electricity in hydraulic power plants	blue
		unknown or unspecified	grey

if the medium of a pipeline you are tagging is not listed here, please choose a meaningful value at your own discretion.

if the medium is not known, do NOT specify the substance=* tag.

• I oppose this proposal. - Idea of proposal seems to be very good and useful, while keys, used for it (such as "type=*"), are interfering with other schemes and using nonsense namespaces (such as "place:"). I described the problem on Discussion page. BushmanK (talk) 20:41, 12 December 2014 (UTC)

• I approve this proposal. - Even there possible overlapping in minor tags, (capacity=* is not free text, but sometimes integer used to mark number of parking lots for example) it might be resolved quite easily since pipeline geometries are quite easy to filter (distinguish from amenity=parkings for example).

• I approve this proposal. - Yes, the place-namespace isn't established, but still I think this is a good proposal. I could imagine to use the place:origin and place:destination tags for labeling the pipeline in a rendering or something like this, really no reason to vote no to the whole proposal. --Dieterdreist (talk) 17:47, 16 December 2014 (UTC)
