It's a millimetre-precision version of the Ordnance Survey grid 
reference. For conversion, see e.g.

Re: [Talk-GB] Rights of way vs. tracks

[Edward Bainton]

This is just fantastic, thank you.

Looking at the definitive map there is a RoW there, but it seems that the
path as shown on OSM  is only
roughly right: it should actually run from the road at an angle of ~240deg
rather than the ~220deg OSM shows, meeting Ermine Street a few tens of
metres further north.

The argis.com map that Peterborough City Council uses

gives it as a FP called "Ailsworth 6" running from 511,025.344 298,855.444
Meters to 510,856.672 298,723.814 Meters

I don't recognise that coordinate system: is it any help for OSM?

Or is there a way to use those coordinates on the ground to follow Martin's
excellent suggestion to retread the path, exactly where there is a right to?

And generally, are we allowed to copy from the definitive map, if we copy
the RoW info only and snap that to OSM data rather than OS underlying data?

Thanks for all points made.

I've edited the relevant wiki page to make it clearer:

If something is designated as a public bridleway add the 
"designation=public_bridleway" tag.  This is separate to the highway tag 
- that might be highway=bridleway, but as you point out could very 
easily be highway=track or highway=service.  I've also seen examples

There is absolutely no indication of it on the ground: no beaten path,

one at the NE end, open country).


Do I delete as probably sourced from OS, or leave as it's a right of way?


That's a good question.  Cambridgeshire is listed at 
https://wiki.openstreetmap.org/wiki/Contributors , so I suspect that the

https://wiki.openstreetmap.org/wiki/Import/ODbL_Compatibility .


If there's no physical access through a hedge I'd definitely ensure that 
there isn't a "highway=footway" running through a hedge.


Given the complicated history of the ways involved, it isn't necessarily 
the case that someone "copied from OS"; they may just have seen a public 
footpath sign at one end and tagged the way there, unaware that the 
footpath crossed several roads and went through a hedge.  I've certainly

Re: [Talk-GB] Rights of way vs. tracks

[SK53]

For the bridleway map with highway=track, designation=public_bridleway.
Basic access rights can be inferred from this combination, but explicit
tagging does no harm (although it does make it a little harder to ensure
these are correct if there is a change in status). One of the beauties of
OSM is that we can represent the same PRoW as a driveway, followed by a
track, followed by a footpath or bridleway. The highway=bridleway tag
should be reserved for those public bridleways which do not follow a track,
service road or even an adopted highway. On PRoWs bridleways should have
different types of gates, much higher headroom, and, in some places,
abundant evidence of horses. I have also used highway=bridleway for
permissive access to field headlands, such as those
 in the
Leicestershire village of Horton.

Rights of way which exist but which no traces are evident on the ground can
be mapped in two ways:

   -  Not at all. I took this option in Carmarthenshire
   

   where paths may be signposted but soon disappear into peoples gardens,
   jungles etc. Representing that they exist in any meaningful way for map
   users is just not a reflection of what is on the ground.
   -  Map the line of the PRoW solely with the designation tag. My
   favourite example  is
   between Wellow & Laxton. Bridleway signs exist at both ends of the relevant
   path, but a deep ditch & heavily ploughed fields are a massive disincentive
   to use when there is a perfectly viable alternative along the edge of the
   wood 100 m away. Similarly I've seen a stile embedded deep in a hedge as
   evidence that a right of way exists & that a footpath once existed. Again I
   just used designation as the main tag.

Good places to look at PRoW mapping are the locations where several of us
have met up to map paths (links to Andy Townsends maps, but you can toggle
to the main OSM style):

   -  Hanbury
   
,
   Staffs, see write-up
   

   .
   -  Abbots Bromley
   
,
   Staffs,
   -  Ipstones
   
,
   Staffs
   -  Scalford
   
,
   Leics
   -  Gringley-on-the-Hill
   
,
   Notts
   -  Lees
   
,
   Derbyshire

Several very experienced footpath mappers have participated in these
events, and have worked together to add the detail you see on Andy's map
(pan to the edges & in most cases you'll see the difference) so I think
it's reasonable to describe the results as representing a consensus.
Elsewhere the Peak District in general is very well-mapped for footpaths
and has had many contributors, so offers a bigger set of useful examples:
however this is popular walking country and paths fallen into disrepair
will be rarer.

HTH,

Jerry

Re: [Talk-GB] Rights of way vs. tracks

[Edward Catmur via Talk-GB]

The documentation is for the general case, where a public bridleway is
physically a bridleway. (There are also private bridleways.) Here you
should tag highway=track horse=designated foot=designated vehicle=private
designation=public_bridleway. You may need to break the track if it
continues with no right of way at some point.

Re: [Talk-GB] Rights of way vs. tracks

[Martin Wynne]

There is absolutely no indication of it on the ground: no beaten path, no
fingerboard, no break in the hedge at the SW end (it wouldn't need one at
the NE end, open country).

Do I delete as probably sourced from OS, or leave as it's a right of way?


First thing to do is check the County Council's definitive map (it 
should be online, with reference numbers) to check that it is still a 
public right-of-way, and hasn't been closed or diverted since the OS map 
was made.


If it is, you walk to and fro along it until there is some evidence on 
the ground, and then you map it as highway=footway with 
designation=public_footpath and foot=designated.


cheers,

Martin.

[Talk-GB] Rights of way vs. tracks

[Edward Bainton]

Hi all

Two rights of way questions for England & Wales:

1.
What do we do when a public bridleway passes down an otherwise private
track, as here ?

Both the track the the right of way are 'on the ground'.

Do I mark a track, with all it's passability tags, and then tag horses &
foot=designated? That acknowledges the track, but disregards the
documentation here

which says "Public bridleways should be tagged: highway
=bridleway and designation
=public_bridleway" .

Or do I follow the documentation and disregard the visible track?

Same question for public footpaths.

2.
What should I do with this footpath
, which appears on OSM and
also on the OS map

as a public footpath.

There is absolutely no indication of it on the ground: no beaten path, no
fingerboard, no break in the hedge at the SW end (it wouldn't need one at
the NE end, open country).

Do I delete as probably sourced from OS, or leave as it's a right of way?

(For some reason the history shows me as the author of Version #1 of that
path, but actually it long predated my edits in this area. iirc the
history, before my edits elsewhere apparently over-wrote it, showed it as
added several years ago)

Thanks,

Edward (eteb3)
