Hi David
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?
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.
