<DIV><FONT face=Arial>Hi,</FONT></DIV>
<DIV><FONT face=Arial>I've just read Colin's reply again - more thoroughly this
time! I should have made it clear that I was thinking of paths where
there's only a slight discrepancy - up to 40m say. For example where
there's no longer a stile through a hedge because everyone heads for the nearest
gate. Or because people walk in a straight line from A to be across a
field instead of following the curved PROW. In such a situation is it
appropriate to not tag anything as a PROW or to mark the de facto path as a
PROW? Sorry for any repetition.</FONT></DIV>

<DIV><FONT face=Arial>Hi,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I'm a relative newcomer to contributing to OSM but
trying to get to grips as quickly as possible with the consensus on
various topics, one of which is PROWs. The emails below raise questions
I've had for a while.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I'm hoping for guidance as p</FONT><FONT face=Arial>aths
can include these two types:</FONT></DIV>
<DIV><FONT face=Arial>1. Definitive PROWs (but subject
to subsequent Orders - whether deviations or
extinguishments)</FONT></DIV>
<DIV><FONT face=Arial>2. De facto paths generally thought to be
PROWs.</FONT></DIV>
<DIV><FONT face=Arial>Most of the time the two are coincident.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Where they're not coincident, is it the case
</FONT><FONT face=Arial>that we should map the de facto paths?</FONT></DIV>
<DIV><FONT face=Arial>In such a situation should the de facto paths be
tagged as PROWs and/or given the highway authority's reference?</FONT></DIV>
<DIV><FONT face=Arial>Where there's a difference should we also map the
definitive PROWs in some way (even if they go through a private house - I'm
not making that up)?</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I realise there's an important but separate issue of
copyright if the route can be determined only from the definitive map (based
on the OS map).</FONT><FONT face=Arial></FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Regards,</FONT></DIV>

Data is not always accurate.</DIV>
<DIV><BR></DIV>
<P>My understanding is that the definitive data held by the appropriate
local authority is exactly that, definitive. There may be legitimate errors
in there of course, but where a path has been willfully and legally
rerouted, that is a different type of error - lack of currency, i.e. an
order has been made to reroute the path but they haven't yet got round to
updating the Definitive Map and the Definitive Statement.</P>
<P>Any paths that no longer follow the official route (as per the DM/DS)
should not be tagged as PROW and probably as access=permissive unless they
go across otherwise public land. The official route is still a public right
of way, it's just no longer usable as such.</P>
<P>Do you have a way of feeding these discrepancies back to Somerset CC, to
establish whether they are true errors, lack of currency or illegal
reroutings?</P>

class=pre>Hi<BR><BR>If you're using local authority data/os open data to
map paths, as a contributor current is in Somerset, please don't assume
their layout corresponds with what's on the ground or is more accurate
than what's mapped in OSM. These official ways are often outdated, being
based on redundant features such as grubbed up fences & hedgerows.
Gate & stiles occasionally get moved. These tweaks often don't make it
back to the Definitive Map.<BR><BR><SPAN
