#17034 new enhancement

Add support for power=connection

Reported by: Penegal Owned by: team
Priority: normal Milestone:
Component: Internal preset Version:
Keywords: power connection preset warning validation Cc:

Description (last modified by Don-vip)

There happens that crossing power lines are connected with one another without any supporting pole or tower, such as on the attached picture. In this case, the lines share a node tagged power=connection, but JOSM has no support of this configuration: it has no such preset, and warns about power line nodes without power=(pole|tower). Could this preset be added and the relevant warning adapted to not show when the node is tagged power=connection?

Nice one
power=connection haven't been reviewed yet.
It has been part of a huge (rejected) proposal in 2014 : https://wiki.openstreetmap.org/wiki/Proposed_features/Power_paths_refinement
Despite it is currently used about 1000 times, I'm not sure to add it as a preset.

Nevertheless, JOSM shouldn't warn users when two power=* lines connect each other.
The warning should raise if and only if the node is shared by both power and non-power objects or standalone in a single line.
We can find connection nodes with power=switch in substations for instance

Hope it helps

Replying to francois.lacombe:

I'm not sure to add it as a preset.

Is there a reason? The tag seems fine to me.

comment:5 Changed 9 months ago by francois.lacombe

It is not currently documented on wiki.
Despite the idea sounds good, if there is no connection, then there should be no shared node between nodes.
connection=* (especially connection=no) is find to say that several lines sharing the same pole aren't connected.
Additional design should be done with those two tags.

I fully agree on the warning anyway

In 15088/josm:

  • see #17034 - add icon proposals for connection nodes of power lines
  • add svn:mime-type of images

Removing the milestone as first power=conection vs. connection=yes/no should be decided (not in this ticket).
I added 3 possible icons for later use to the nodist folder:

Thank you Klumbumbus

I'd be in favour of 3rd icon from your proposal
First two, with straight connections may let mapper think they refer to bundles link like here : https://wiki.openstreetmap.org/wiki/File:JP_Power_Wires_Fivefold.JPG

Regarding power=connection vs connection=* I think both should be valid, depending on the previous usage of power=* for another value (like poles)
