An underground pipeline or cable will sometimes have an access road,which will be represented as a surface feature, but if there is no surface feature, how will it show on the OSM map? Are there Presets for either underground water pipelines, or telecommunication cables? |

location=underground would seem to be the choice unless in a self supporting structure such as a tunnel.
Tag:man_made=pipeline suggests using location for 'underground', 'underwater' or 'overground' pipes. How it looks on a map will depend on the rendering scheme used. eg the underground rail shows well on the openstreetmap transport layer. I couldn't find an example of comms cables underground. Note that the key layer -1 does not indicate undergound, but instead layer indicates relative position to other objects. |
