I don't have an example, but I have seen that too.
Technically yes, but there are some cases when tagging redundancy is worth it or even useful for clarity. For example, if it's in an area where you might expect access=* or foot=* to be no, access=yes can be used to confirm that the way _is_ in fact open to the public (signed public route through a private area, perhaps? like a golf course or a quarry?) and foot=yes can be used to confirm that pedestrians do have access there as well (perhaps it's on a motorway but pedestrians are allowed for some reason?). You can also use this to communicate the actual value of the access=* tag to your fellow mappers. In an area where access is unclear, if you tag access=yes, you are saving other mappers from wondering if the way is actually public, or if it has not yet been surveyed/edited to add access=private. (In programming terms, access=yes is true, access=no is false, and lack of an access=* tag is null) > However, access=yes is a pretty broad statement.

If the land manager is not aware of a mode of transport, are they really in position to prohibit it right now? And in the future, pedestrians could be prohibited too, and tagging would have to change as well. --Jarek _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
