you know that all services not OS are based on the Openstreetmap mapping data?
I’ve looked on open street map.org before and it’s great. Footpaths and bridleways correctly identified.
I’ve just checked FatMap’s about page – yes they do use osm, but also a list of about 20 others. One of those must explain this:
that’s the fun loops around the little piggies. Not so little trust me.
I wondered if the long dashed lines mean it’s a track but infer no right of way. So looking elsewhere, nearby:
That track running up to stoke clump is a bridleway. It continues as a bridleway but is marked with dots? Meanwhile all the other dashed trails shown are not public rights of way. FatMap seems useless for English right of way to me, unless I’m missing something.
