I am having trespass issues with both of these routes, so appreciate that in the case of the track that it is marked as private as it physcally exists. Request that the line of the non-footpath to the East is removed from this source as it does not exist in reality. Just because a GPX trace exists, the person who recorded it was trespassing, there is no reason for it to remain.
Lower Farm PROW ends at the Y-Junction of the two tracks. Middle Farm PROW is as defined by by Ordnance Survey 1:25000 mapping data.
With regard to mapping changes I have only just found out about this resource so belatedly updating inaccuracies.
Many thanks.
