Utility markers can be seen pretty everywhere in cities and in countries also. OSM use to map them with several keys, depending on which kind of utility or purpose they was intended for. This proposal will try to summarize many sort of them and propose a unique set of values for the {{Tag|marker}} key.

Currently, OSM only knows certain markers, for pipeline and underground power cables but there are many more situations where markers are used. A side issue is markers aren't properly part of the line they refer to. Then it may be confusing to use {{Tag|power}} or {{Tag|pipeline}} as it leads to think the marker is directly installed on the pipeline or cable.

<br/>It seems interesting to group the general knowledge of markers under a single key instead of defining the same concepts on each mapping subject.

==Proposal==
It is proposed to use {{tag|marker}} key to map markers according to their shape and {{Tag|utility}} to state at which activity they refer to, without preventing to extend it to any other feature in the future (by defining different new values). Usage of {{Tag|support}} is not required anymore since design information includes used support.

Usage of {{Key|support}} is not required anymore since design information includes used support.
<br/>This proposal focuses on man made infrastructure buried underground: pipelines, power cables and supplies, telecommunication lines (both copper and fibre) and fire hydrants.

As a consequence markers aren't properly involved of the process of the infrastructure they refer to, it is also proposed to make {{Tag|marker}} incompatible with {{Tag|voltage}}, {{Tag|frequency}}, {{Tag|pressure}}, {{Tag|diameter}} since it's not appropriate properties.

There are exitsing keys like {{Tag|pipeline|marker}} that should not be used anymore as to not clutter naming intended for directly-connected-to-pipelines and operational involved features (valves, pumps, tanks...).

{{Tag|pressure}} and {{Tag|voltage}} are explicitly not mentioned here as it's not a property of the marker itself but of the buried infrastructure it refers to. You'd better to add them to corresponding feature and not on the marker with these keys. You can still add a {{Tag|note}} or use {{Tag|description}} as to not loose information.

Proposal status: Approved (active)
Proposed by: Fanfouer
Tagging: marker=* & utility=*
Applies to: node
Definition: Improve utility markers mapping by consolidate usage of marker key
Draft started: 2019-05-09
RFC start: 2019-07-14
Vote start: 2019-10-12
Vote end: 2019-10-26

Utility markers can be seen pretty everywhere in cities and in countries also. OSM use to map them with several keys, depending on which kind of utility or purpose they was intended for. This proposal will try to summarize many sort of them and propose a unique set of values for the marker=* key.

Rationale

Utilities feature all networks that provides useful energy or fluids to human activities (industry, domestic appliances, public works...).
These networks can be really dense and often buried undeground in cities as to reduce their vulnerablity, visual impact and improve people security.

Markers are used to remind us about their underground presence. Any forgotten gas or high voltage line can have desastreous impact on any occasional digger reaching them.
Furthermore, markers are great visual helps for navigation or location on unknown places. Refs and colour can help anyone who want to locate on a map.

Currently, OSM only knows certain markers, for pipeline and underground power cables but there are many more situations where markers are used. A side issue is markers aren't properly part of the line they refer to. Then it may be confusing to use power=* or pipeline=* as it leads to think the marker is directly installed on the pipeline or cable.
It seems interesting to group the general knowledge of markers under a single key instead of defining the same concepts on each mapping subject.

Finally, marker shapes are designed for a given purpose, depending to whom is supposed to read them. Underground pipelines may be inspected by plane or helicopter and some markers come with kind of roof cover displaying signs. Documenting shapes may improve rendering and knowledge of their shape as to distinguish them on ground as landscape elements.

Proposal

It is proposed to use marker=* key to map markers according to their shape and utility=* to state at which activity they refer to, without preventing to extend it to any other feature in the future (by defining different new values). Usage of support=* is not required anymore since design information includes used support.
This proposal focuses on man made infrastructure buried underground: pipelines, power cables and supplies, telecommunication lines (both copper and fibre) and fire hydrants.
Markers will be described with existing and meaningful keys material=* and location=* keys which won't be modified by this proposal.

As a consequence markers aren't properly involved of the process of the infrastructure they refer to, it is also proposed to make marker=* incompatible with voltage=*, frequency=*, pressure=*, diameter=* since it's not appropriate properties.

There are exitsing keys like pipeline=marker that should not be used anymore as to not clutter naming intended for directly-connected-to-pipelines and operational involved features (valves, pumps, tanks...).

How to map

Once located on ground during a survey or got from public information / street level pictures, just put a node on the exact point and add following tagging on it.
For sake of One_feature,_one_OSM_element, each marker should get its own node on OSM at the exact place it belongs to.

Markers will surely indicate that a particular linear feature (pipeline, power cable...) lies next to it. Nevertheless, markers are installed to be seen and prevent damage at various distances from the feature they refer to. So it's not recommended to put markers directly on pipeline or cable ways, unless the marker is seen fixed on them. Markers are not devices with direct impact or sensing on live features so share nodes between lines and them wouldn't be accurate.

Tagging

Here is a summary of recommended tagging for a utility marker

Key Value Comment Recommendation
marker <marker shape> The node corresponds to a marker seen on ground mandatory
utility <utility> Activity the marker is referring to recommended
material <material> The material composing most of the marker (referring to the support if dedicated) optional
location <location> The physical location of the marker, often overground optional
ref <marker ref> If available, the ref as it can be read on the marker optional
operator <company name> The name of company who operate the marker (and often the associated linear feature, cable or pipeline) optional
colour <colour> The most representative colour of the marker optional

pressure=* and voltage=* are explicitly not mentioned here as it's not a property of the marker itself but of the buried infrastructure it refers to. You'd better to add them to corresponding feature and not on the marker with these keys. You can still add a note=* or use description=* as to not loose information.

And a list of possible values for marker=* depending of their design.
This list can be completed as needed with equivalent values valuable in other fields of knowledge if needed.

List of possible marker=* values
Key Value Comment
marker post Standard kind of marker composed of a pole/mast with useful information written on it. The support have to be dedicated to marker, see plate for other situations
aerial A marker that is intended and designed accordingly to be seen from aircraft dedicated to networks inspection.
pedestal Unlike a stone, pedestal are man made and can be whether in plastic or in concrete. Useful information is found on top of them.
stone A stone is a natural support where useful information is directly etched or painted on it.
plate A kind of sign installed on walls without any dedicated support indicating what is installed underground nearby
ground The marker is directly installed on ground with help of fixation support to hold it in place

And a list main values for utility=* to indicate to what utility it is about. It sounds similar to substance=* for pipelines but it's not, for instance both substance=steam and substance=hot_water may be valid for utility=heating.

List of possible utility=* values
Key Value Comment
utility gas Any infrastructure or facility involved in gas transport or distribution
oil Any infrastructure or facility involved in oil/hydrocarbons transport or distribution
chemical Any infrastructure or facility involved in chemical fluids transport or distribution
heating Piping intended to transmit steam or hot water to buildings in cities for district heating
power Any infrastructure or facility involved in electricity transport or distribution
street_lighting Street lighting switches and cables can pass through some cabinets all along the streets.
telecom Lines and facilities intended to carry digital information on long distance or towards local customers
television Lines and facilities intended to carry digital television signals mainly towards local customers
waste Pipes and facilities intended to transmit waste to treatment plants in large cities
water Any infrastructure allowing natural, raw or drinkable water to go from production to consumption.
sewerage Infrastructure that took used water from domestic or industrial activities to waste water treatment plants.
hydrant Any device intended to provide water to fire & rescue teams. This value doesn't mean it's an actual hydrant but regards the infrastructure dedicated to feed them.

Edition management

This proposal propose to replace some values, as described below.
