A grounding wire is a bare wire buried in the ground used for realization of a ground connection. Extensive horizontal groundings can be found at HVDC schemes and transmitters, especially those working on frequencies below 10 MHz.

How to Map

Draw a way way following the path of the grounding. It is not necessary to tag grounding wires with a layer=* unless two grounding wires cross each other. As groundings can consist of a single vertical rod, this tag can be also used on a node node.


When known, you can also add at least these tags to further define the line:
