I am searching for 10 OSM Relations that define the boundaries of the 10 parishes of Guernsey (Channel Islands). Do they exist? If so, how do I find them? Or can someone just point me to them?
I fear that they are not mapped yet. The only borders for Guernsey are admin levels 2 and 4, see https://osm.wno-edv-service.de/boundaries/ (use your osm account to log in).
