Hi all
First of all: Happy New Year! I have used some of my spare time to improve OSM around my area. A couple of questions came up I couldn't answer myself quickly using the OSM wiki or Google. So here you go:
1. Administrative boundaries: around Albisriederplatz the boarders are set as a separate way on top of the tramway way. It's very hard to select the right one. Shouldn't that be merged to one way only? Or set as relation? BTW there seems to be a problem with the boundaries anyway, as they are not closed.
2. How are pedestrian crossings supposed to be tagged, when the highway lanes are separated and there is a tramway in between? Should the lanes be connected or is it enough to simply put a crossing tag to all the nodes crossed?
3. I had to adjust some public transport relations due to the changes I made. I noticed that there are always to relation per bus line (at least for 33 and 72). Is that the way it's supposed to be?

Hi Pascal,
A good place to discuss such things is the monthly meeting (Stammtisch) in Zürich which usually takes place on 11th every month near the bqm at ETH. (http://wiki.openstreetmap.org/wiki/DE:Switzerland:Z%C3%BCrich/OSM-Treffen)
- Administrative boundaries: around Albisriederplatz the boarders are
set as a separate way on top of the tramway way. It's very hard to select the right one. Shouldn't that be merged to one way only? Or set as relation? BTW there seems to be a problem with the boundaries anyway, as they are not closed.
Administrative Boundaries are imported from an official data source. As they have nothing to do with tramways or other ways, they are treated separately. Dependent on what software you use for mapping, there are efficient ways to select overlapping ways.
- How are pedestrian crossings supposed to be tagged, when the
highway lanes are separated and there is a tramway in between? Should the lanes be connected or is it enough to simply put a crossing tag to all the nodes crossed?
In my opinion, a tag on all nodes should be sufficient. Connecting the lanes by a footway or path is kind of micromapping which makes only sense if all sidewalks have been mapped.
- I had to adjust some public transport relations due to the changes
I made. I noticed that there are always to relation per bus line (at least for 33 and 72). Is that the way it's supposed to be?
There is a relation for each direction of the bus line. The 33 for example uses different ways near Wollishofen.

Hi
According to a news article [1] (in german) the municipality (Gemeinde) of Belpberg [2] has been merged into the municipality of Belp (Gemeindefusion) taking effect on 01.01.2012.
Are such changes periodically imported from the Swisstopo dataset? If yes, how should we handle such cases in the meantime?
Is there a guide/tread somewhere (wiki?) how to proceed in this case?
The following steps come to mind:
- change the places tag (place = village -> place=locality) - remove boundary admin level 9 - adjust all addr:city tags? - adjust all addr:postcode tags? - adjust the entry in opengeodb?
what else?

Have a good 2012.

Hi David

The data from Swisstopo does not have any "change sets", so importing them automatically would mean to delete *all* old boundaries and reimporting the whole new dataset.
But there is a 'Historisiertes Gemeindeverzeichnis' where all changes are documented: http://www.portal-stat.admin.ch/gde-tool/core/xshared/gewo.php
Is there a guide/tread somewhere (wiki?) how to proceed in this case?
The changes for January (and September 2011) were done manually by me - in an undocumented but more or less coherent way. :)
The following steps come to mind:
- change the places tag (place = village -> place=locality)
- remove boundary admin level 9
- adjust all addr:city tags?
- adjust all addr:postcode tags?
- adjust the entry in opengeodb?
Don't mix 'Gemeinde' with 'Ortschaft' bzw. 'Dorf'!
For all the changes I observed, the old names don't disapear, neither do the post codes. I created new boundary-relations with admin_level=9 for the former municipalities (admin_level=8).
OpenGeoDB is not maintained any longer and consensus is (?), that these tags can be deleted.

Yes, this would help to keep the OSM db clean :->! But do it judisciously (see the posts in Talk-de about "OpenGeoDB eingestellt", 2. Januar 2012 21:24).

Hi Phono
Thanks for your answer. It helped. I was planing to join the Stammtisch today but didn't make it to Zurich in time. Next month.
Cheers Pascal
