I am staying with my folks in the countryside (leahill.co.uk) and took the opportunity to walk a few footpaths. A question which arises is whether to map the physical features on the ground or the rights of way. For example, Goyle Acre Lane is a public byway, meaning not only pedestrians and horses but even motor vehicles have a right to use it. Yet for some of the route there is no physical road at all - at best some muddy tyre tracks through a field. For now I have mapped it all as highway=track ('Track road' in Merkaator). Similarly I have added a highway=footway for a public footpath that similarly goes through a field.
On the other hand, in London I often find physical roads which are not rights of way, such as tracks to garages.
What's the correct way to map this distinction?
