Hallo
Beim Import der Basler Wohnviertel habe ich auf der Imports-Liste Hinweise auf fehlerhafte Boundaries in der Schweiz erhalten (siehe unten). Vielleicht will sich mancher um ein paar in seiner Nähe kümmern...
Oder ist es gerade der falsche Zeitpunkt wegen Gemeindemutationen!?
Gutes Neues! Johannes

What other errors do you see? Can you tell me an Overpass query that your insights are based on?
Sorry: I wanted to say "... to correct this and other **possible** errors...".
As I was just looking for an example of admin_level=9 administrative divisions and I found that duplicate example, I find it quite probable that there might be other mistakes here and there. It's only a guess, and in any case I am quite sure this happens with mostly all countries. Sometimes errors come from newbies who don't know really how to handle a boundary relation.
The overpass to download all administrative boundaries of Switzerland that I used is:
[timeout:150]; ( node["boundary"="administrative"](area:3600051701); way["boundary"="administrative"](area:3600051701); relation["boundary"="administrative"](area:3600051701); ); out meta;
;
out meta;
Running the JOSM validator I can give you some error examples:
1. Heimiswil [1] in Canton Bern has 470 duplicated nodes.
2. Bonfol [2] and Vendlincourt [3] nodes, that are duplicated as members of their respective relations with label and admin_centre roles.
3. Zürich airport area [4] is tagged as boundary=administrative, and crossing the boundaries it finds on its way.
4. Apart of Zürich airport, there are other 4 boundary=administrative segments around Switzerland without the admin_level tag. One exemple is this one [5], that belongs to 2 admin_level=6 entities, 2 admin_level=8, 1 admin_level=9 and 1 admin_level=10.
The rest of the errors, like 25 unclosed boundaries, you can get them from the JOSM validator.
Cheers,
Rafael.

Hello,
Je m'occupe depuis quelques jours de corriger les erreur dans les polygones dont certains concernent les boundary. J'ai aussi constaté qu'au moins 4 cantons sont mapé en double. Je vais regarder les erreurs signalées dans ton message. Mais si quelqu'un souhaite aussi le faire, qu'il n'hésites pas.
Cordialement, Marc
