Take into account building=transformer_tower when validating power lines supports

[Penegal]

Hello, there (again).

Currently, when the validator processes power lines, it complains when a node on the power line is not tagged as a pole, tower… The problem is that this list of required tags does not include building=transformer_tower, either as a node or as a way.

Well, typically, when a line gets into a transformer tower, it enters it through glass insulators embedded in the building wall. In this case, the validator should stop complaining about an abnormal or missing support on the line; an additional test should be made: if the node is a building=transformer_tower, or a node on its way, this node must be an end of the power line; I'm not sure this test is useful, though, but it could be, depending on the circumstances, and as a line is not supposed to go through a transformer tower, but end in it.

Regards.

I agree. @team: this is not a mapcss but a java test :)

@Klumbumbus: Have a look at PowerLines.java​ (top part where the constants are defined). If you feel daring, you can try to make a source code change. If not, let us know. ;-)

I'm not able to fix it. The constants are only values of key power, however we need building. So I don't know how to define the key. Also I don't know how to define that it should be a node with building=transformer_tower or a node as part of a way with building=transformer_tower.

Would that fix the issue?

Accidentially did checkin this in r10363. Hope it was correct :-)
