This seems interesting: https://www.ramblers.org.uk/get-involved/out-there/out-there-getting-paths-on-maps/mapping-scotland-paths.aspx -- I'm not quite sure why they don't just use OSM (but I've not really read into it yet).
What background mapping are you using?
We currently use OpenStreetMap as the base map for the Scottish Path Map. OpenStreetMap is used by many online mapping services, including those provided by some Scottish Government agencies.
OpenStreetMap is built by a community of mappers that contribute and maintain data about roads, trails, cafes, railway stations, and much more, all over the world.
OpenStreetMap is not designed specifically as a tool to support walking, so its contributors simply map geographic features that exist on the ground.
This means that there may be geographical features present on the base map where access rights do not apply.
