Hi all.
As far as I understand there was an Import of the Municipalityboundaries from swissboundaries at around 2011 [1]. There are also annual "Municipality Mergers" [2] for municipalities that were merged. Is there is also a defined workflow to keep changes on the geometries of the municipalityboundaries (admin_level=8) up to date in openstreetmap? For example, right now there are differences in Lakes like Lago Maggiore, Lago di Lugano and Lac Léman where the boundaries in osm follow the coastline but in swissboundaries the middle of the lakes. There are also other changes e.g. [3] that are not up to date in osm [4].
If there is no such workflow, I assume it is ok to adjust the border manually by following the vertexes of swissboundaries?
Thanks for your advice Daniel
