I think most of us are working with what's on the ground though there are sections of NCN that we ride that are poorly signed though the route is in use on the ground if you know where to go.
Generally speaking you should find the routes in OSM pretty reliable, if at times disjointed. Bear in mind also that the OS prints routes on its maps that the LA and Sustrans provide them with. In the Sustrans mapping some are wrongly routed because they were created off the 1:50,000 mapping. Sustrans has moved all its GIS over to 1:10,000 mapping now and they are in the process of cleaning up routes, crossings and access point data. I'm doing that currently for them for instance in Birmingham. One way to fix problems with OSM data for cycling is to submit a routing bug via cyclestreets.net Cheers Andy >-----Original Message----- >From: talk-gb-boun...@openstreetmap.org [mailto:talk-gb- >boun...@openstreetmap.org] On Behalf Of Henry Gomersall >Sent: 01 July 2010 9:59 AM >To: Richard Fairhurst >Cc: talk-gb@openstreetmap.org >Subject: Re: [Talk-GB] NCN numbering > >On Thu, 2010-07-01 at 01:49 -0700, Richard Fairhurst wrote: >> I think, ultimately, Sustrans' internal semantics shouldn't really >> concern >> us documenting the system from outside (even those of us who also >> happen to >> be rangers ;) ). > >Are the cycle routes representative of what is on the ground, i.e. What >the little signs say, or are they representative of some document >somewhere? > >As a cyclist, I'm keen to say I'd find the a representation of what is >on the ground more useful.
