Great, thanks.  Each path has a name, e.g.:
   DN Seaton Footpath 2
It would help if you gave the names of some of the paths you have problems 
with.  Sorry, I should have asked this earlier.

I'm not sure if anyone will be able to help bring some degree of firmness
to this, but it is my belief that roads that are on the Local Authority
list of streets appear with a solid border in OS StreetView map. So for
your example:

http://os.openstreetmap.org/?zoom=15&lat=50.43928&lon=-3.67146&layers=B0

Whereas rights of way either do not appear at all, or part appear as a grey
road with no border (for access to some building). For example in the
following link you see a road from Keepers Cottage to Grotto Lodge. I
looked this up and it is a right of way "Byway Open to All Traffic". It
runs beyond Grotto Lodge, East past Copse, before turning south round
Rabbit Warren! You can make out which way the BOAT goes by the missing
section in the woods.

http://os.openstreetmap.org/?zoom=16&lat=51.31394&lon=-1.37819&layers=B0

== Question ==

How to indicate this by a tag so that routers are happy yet we still know
it is a "road". I would start with "operator=" to
capture that it is on the list of streets (perhaps still worth checking).
Highway unclassified vs highway track is a difficult one - I'm happy to sit
back and hear any arguments from either camp. Either way, "lane=1" is
probably a must. And ideally we need a "not really recommended" / "avoid
unless the alternatives are just as bad / far out of the way" type tag. As
far as I know we don't have one. :-(

This is one:

The ones I have surveyed are glorified farm tracks with mostly gravel or
broken concrete surfaces, currently tagged as highway=track which seems
appropriate given the surface.

No extra "designation" tag is needed in my opinion. If they are on the
authorities list of streets, then they are legally exactly the same as any
other road. Therefore highway=unclassified would be fine. The issue arises
when they are not well maintained, narrow, or not suitable for some larger
vehicles. We really need some way of identifying this in a tag so that
routing engines can suggest an alternative route. I guess some people may
use highway=track to make a distinction, but I'm not convinced this is
right...

Ideas welcome (I've not seen enough examples to get an understanding of
what these roads are actually like on the ground - photos welcome too)

In regards to "Other roads with public access" (ORPA) - this is a term that
the Ordnance Survey have used, in other places they are called
"Unclassified County Road". Most often they are legally the same as a
normal road (and should therefore appear in the Local Authorities list if
streets, in which case they do not need to appear in the Definitive Map /
Definitive Statement).

If you are interested in following it up it may be worth asking your local
authority if it appears in their list of streets. If not you could ask why
not. Basically we want all routes to exist in either the list of streets or
the Definitive Map/Statement by 2026.

For the misalignment: this may be due to an incorrect projection being used
(similar as to what happened with the first release of OS OpenData). I'll
check it when I get a spare moment.

Thanks for your work on this.

I've been looking at the Devon data and have integrated a small amount of
it local to me. There are a whole bunch of unsurfaced green lanes around
here with public access that are not in the dataset. They are often marked
on OS Explorer as "Other routes with public access". Any idea why they are
not included and should there be a legal designation for those?

I also noticed that the Devon data (using the kml from your site in josm)
appears to be consistently offset a few metres south of where it should be.
Not a big deal just FYI really.

Barry,
Local government regions in England can be very confusing. For public rights

and Statement lies with those regions that are “surveying authorities”. This
is the same as the 152 (151 if you exclude the “City of London”) Local
Authorities listed in the Principal Authorities table:

A belated thank you for that message which helped me a lot.

I've now added a section for Wales to:
   http://wiki.openstreetmap.org/wiki/UK_local_councils
that gives some basic information.

I hope it's OK.
