Winter-only snowmobile routes are mapped if they are signed. Create a route relation with type=route + route=snowmobile (used 141 times) - see https://wiki.openstreetmap.org/wiki/Tag%3Aroute%3Dsnowmobile
Please only use highway=track when there is an forestry or agricultural road / track which is passable by 2-track vehicles such as farm tractors, logging trucks, or 4wd cars. -- Joseph Eisenberg (You might try the Tagging mailing list for questions about how to tag something: tagg...@openstreetmap.org) On Thu, May 7, 2020 at 8:43 AM Kevin Broderick <k...@kevinbroderick.com> wrote: > Ideally, I'd say that most snowmobile routes should be relations, not > ways.
