add line_attachment in power supports presets

[francois.lacombe]

Dear maintainers,

The key line_attachment has been very recently reviewed on the wiki and received an approval vote.
​https://wiki.openstreetmap.org/wiki/Key:line_attachment

The post-vote cleanup is in progress and documentation is currently under completion.
It may be great to update JOSM presets as follow :

• Add the key with its four values on power supports presets power=tower, power=pole, power=insulator, power=portal and power=terminal
• Remove anchor and suspension as possible values for tower:type key in any context.
• Warn about the use of tower:type=anchor and encourage the replacement with line_attachment=anchor
• Warn about the use of tower:type=suspension and encourage the replacement with line_attachment=suspension
• Warn about the use of line_attachment on any other feature than a node.

Feel free to ask for any unclear point, all the best

Why is it not listed on ​https://wiki.openstreetmap.org/wiki/Key:line_attachment?

[francois.lacombe]

Because the value doesn't appear in the db yet and the table is got from taginfo.
Look in the wikicode : {{Taglist|tags=line_attachment=suspension,anchor,pin,pulley|with_count=true}}, pulley is actually member of the list but it will only appear once a feature will be tagged with, according to taginfo

[Klumbumbus]

Ah, OK I wasn't aware of the Taglist template.

But line_attachment can be used on power=insulator or power=portal mapped as way!?

[francois.lacombe]

I agree wiki is not clear on that particular case.
Nevertheless, see how it goes when a portal is described as a way : ​https://wiki.openstreetmap.org/wiki/Tag:power%3Dportal
The line(s) is/are connected to it with power=insulator node and then line_attachment should go on the insulator, not on the portal.

I guess it's the same for insulator, the attachment is still punctual.
I'll try to give a better description to it shortly.

Hi Klumbumbus
I think you can go on with his one, on nodes only.
This is because it has to be used on connection between lines and their supports. Is it ok for you?

Is it ok for you?

Yes. I do it after the next release. Now it was too short before the release.

[francois.lacombe]

Great, thank you
No problem regarding time required to achieve it.

Thanks for this detailed list of what actually needs to be done.

Even if it is not explicitly written for the key pole:type, this key is used similar to tower:type (together with power=tower). Especially

• pole:type=anchor (used 1764 times)
• pole:type=suspension (used 1 883 times)

Perhaps the warning to use line_attachment instead should also be used here.

Other values of tower:type could also be found for pole:type like

• pole:type=termination (used 1 260 times)
• pole:type=branch (used 1 327 times)

The values transposing and crossing would make sense, but are not really in use.

[francois.lacombe]

Hi,

Indeed, line_attachment proposal is also valid for pole:type (and any other key :type regarding line support)
I second mdk point to extend warnings about pole:type too.

Regarding the second part, about transposing and crossing. There is another draft proposal that takes care of those values
​https://wiki.openstreetmap.org/wiki/Proposed_features/Lines_management
line_management will end the cleaning of tower:type and pole:type from those particular values.
So i recommend to don't edit anything regarding them for now.

All the best
