Hi all, The line_management=* proposal vote will be open starting on next Monday. https://wiki.openstreetmap.org/wiki/Proposed_features/Lines_management
Clarifications and improvements have been made as follow : * Focus on power only and remove telecom usecase. Proposed terminology is generic enough to be used in telecom sector in a further proposal to give better solutions to tag telecom supports. * Remove line_management=loop and consider them as line_management=branch Proposed key has been used by 6 people on ~450 features already without big problems it seems. Feel free to raise concerns or wait next week to vote on the document. All the best François Le jeu. 9 janv. 2020 à 01:08, François Lacombe <[email protected]> a écrit : > Hi all, > > This proposal is still in RFC and may be voted in a couple of weeks as > evaluation shown no issue so far, at least on transmission power lines. > line_management tag is used carefully for testing. > Read more : https://www.openstreetmap.org/user/InfosReseaux/diary/391058 > > Nevertheless it's an opportunity to review the branch:type tag replacement > with line_management=* > > i'm still looking for an appropriate illustration for two values examples: > * line_management=cross (two or more lines with different directions > sharing the same support without connecting) > * line_management=loop (two or more lines coming from the same direction > are connected as to mock some of them) > > Feel free to propose and complete if you find corresponding situations on > ground > > Thanks in advance > > François > > Le sam. 26 oct. 2019 à 20:59, François Lacombe <[email protected]> > a écrit : > >> Hi all, >> >> After the review of line_attachment key this summer and Karlsruhe >> hackweekend at Geofabrik headquarters last week, let me introduce the >> second stage of tower:type key cleaning project for power lines.
