"swissBOUNDARIES3D contains all administrative units and national boundaries of Switzerland and the Principality of Liechtenstein in vector form. The product is based on an optimized data model for Switzerland and conforms to the data of the Swiss Federal Statistical Office. swissBOUNDARIES3D replaces the GG25 dataset from 2010 onwards."

Even though the downloads on the website has restricted rights, we have a written consent by the head of the Federal Office of Topography (Swisstopo) that we are allowed to import the municipal boundaries into OSM. The data has been uploaded and integrated on the weekend of July 8th/9th/10th 2011 during a mapping party (german).

If you find erroneous data, you can report it on the discussion-page of this entry and we will remove it as soon as possible.


  • 2011-07-09 The import is ongoing...
  • 2011-07-10 Reversion of changesets as the data was not transformed correctly..
  • 2011-07-20 cleanup of old data ongoing. Import probably this weekend.
  • 2011-07-24 2nd run has started -- and finished

Work to do

Adding new relation:boundary for the canton boundaries (admin_level=4) as well as for the Verwaltungskreise (admin_level=5) and the Bezirke (admin_level=6) if any. The admin_level of the ways in these relations needs to be changed accordingly.

The following should be added to these relations:


tags: name, name:*, source=swissBOUNDARIES3D, swisstopo:KANTONSNUM, ref

members: all ways with role outer/inner, admin_centre, label (get the last two from the old relation)


tags: name, name:*, source=swissBOUNDARIES3D, swisstopo:BEZIRKSNUM

members: all ways with role outer/inner, admin_centre, label (get the last two from the old relation)


Keep track of the relation building/border merging work after the import. Add your name to the canton before you start editing. Don't edit cantons where another user is editing to avoid conflicts.

  • For some cantons the relations for admin_level 5/6 already exist from before the import. They are marked with a * (maybe not all). You may reuse these relations.
  • User t-i suggests not to reuse the relations but to create new ones for the new relation because of the relicensing issues.
  • Editing Relation 51701 (Swiss boundary) at the moment:
