Re: [Talk-GB] England Cycling Data project: DfT cycling data now available for merging
One thing I have noticed with the data is that in a number of places the DfT data claims there is an LCN on a major road which I know has no LCN signage (except the odd crossing) - e.g. London Road - or claims that both the main carriageway AND the adjacent cycleway (well footpath with some wobbly painted lines) are LCN - the most obvious being here on the ring road http://gravitystorm.dev.openstreetmap.org/cnxc-app/editor.html?lat=52.99199&lon=-1.14147- i.e. both the cyclepaths on either side of the 40mph ring road are marked as being in the LCN (which tallies with the on the ground situation) but also the main 40mph carriageway (well actually a single line in the DfT data) which has no on the ground signs or even things like ASLs - in these cases is the road really supposed to be marked as LCN? Where it's on a residential road but unsigned on the ground I've been adding it in (most of these fill in the various "missing links" you get from surveying the signs) but on these major roads I've left it incomplete for the time being. Also, does anyone know when the OpenCycleMap data is last from (is there a page showing this?) - I notice that stuff I added LCN tags to on the 9th still hasn't been rendered dispite the tiles being updated on the 18th and currently marked as clean? ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

There's a slight tagging ambiguity when a link route connects two numbered routes, of course: often these will be signed as, say, '(5)' in one direction but '(51)' in the other. For the example in my group's 'patch', I chose to switch over the tagging at the railway station roughly halfway: http://osm.org/go/eutSPzu?layers=C cheers Richard -- View this message in context: http://gis.19327.n5.nabble.com/England-Cycling-Data-project-DfT-cycling-data-now-available-for-merging-tp5713108p5713637.html Sent from the Great Britain mailing list archive at Nabble.com. ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] England Cycling Data project: DfT cycling data now available for merging
Thanks both Andys :) As an example of somewhere this hasn't happened look at the current mapping around St Peter's Basin in Newcastle. It shows and extra spur of the NCN72 along Bottlehouse Street, but actually the NCN72 runs along a parallel road to the north (Saint Lawrence Street). http://www.openstreetmap.org/?lat=54.96592&lon=-1.57369&zoom=17&layers=C I suspect the original mapper was misled by the NCN signs in Bottlehouse Street, which don't have brackets on them. I'll survey it sometime soon and fix it as suggested. -- View this message in context: http://gis.19327.n5.nabble.com/England-Cycling-Data-project-DfT-cycling-data-now-available-for-merging-tp5713108p5713631.html Sent from the Great Britain mailing list archive at Nabble.com. ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

The bracketed NCN number is a relatively new thing from Sustrans. Basically any "route to" or deprecated "braid" should have a bracketed number, though in many locations this may not have happened yet. The number alone without brackets should only be used along the primary NCN route itself.

That's true, and that's why I arranged to have these widths in the "est_width" tag rather than the "width" tag. For the curious, here's the numbers across the database: est_width | count ---+--- 0 | 6 1 | 9 1.25 | 9505 1.5 | 4 1.75 | 25209 2 |18 2.5 | 27090 3 | 2 4 | 3 6.5 | 1 If there's any other questions regarding the data, feel free to ask!

Hmm... would make a degree of sense - but as noted earlier, most NCNs (and other routes) are stored as relations. I guess that ways signed as leading to an NCN could still use ncn_ref=(xx), but we'd probably want to carefully note this approach somewhere on the wiki (probably http://wiki.openstreetmap.org/wiki/Cycle_routes ) -- View this message in context: http://gis.19327.n5.nabble.com/England-Cycling-Data-project-DfT-cycling-data-now-available-for-merging-tp5713108p5713607.html Sent from the Great Britain mailing list archive at Nabble.com. ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb

And I can't think of anything better myself. Given that there is a potential clash with road reference numbers (which rightly should take priority) and there are definitely cases where this arises, then perhaps it would indeed be better to use a different key for the footpath etc numbers. If we do make a decision to go with prow:ref, then I think we should try to bulk change the existing uses of ref for PRoW numbers. It would probably be relatively easy to semi-manually review all 7,000 uses of a ref value on a way with a designation. For example, we should be safe with any values that contain only letters and numbers (so is unlikely to be a combination of two different refs separated by ";" or "/") and ends in "FP n", "BR n", "RB n" or "BY n" where n is any number (so looks like a PRoW number). This will probably cover any that I've added, and I'd be happy for them to be changed automatically. If there were any other common formats, we could probably match them too, and then only have to manually review the much smaller number that's left.

I use "admin:ref" for refs that are predominantly intended for administrative usage, rather than public-facing usage. Now that sounds like tagging for the renderer. The problem in the stated case, is that there is potentially a footpath ref and a road ref. I would want to suggest something like footpath:ref=B64 or prow:ref=B64, but I don't think either is used or documented anywhere. Thanks everyone for the comments I like the idea of prow:ref. I think footpath:ref a bit too specific, we'd then need bridleway:ref, not to mention boat:ref (for byways open to all traffic) which could be just TOO confusing! I've also found one instance of where the problem mentioned by Andy, of a way needing both a road ref and a prow ref, see http://www.openstreetmap.org/browse/way/28919456 which currently is tagged "ref = A49;Cuddington FP 24" Certainly here on the Isle of Wight, I think the use of the reference number has gone beyond just administrative purposes. A large majority of the footpath/bridleway signs have the ref on them (and I think all the more recent ones do). Walking guides and trail leaflets commonly refer to paths by using their reference number. In the UK at present there seem to be 7,004 ways tagged with designation =* and ref = *, of which 941 are on the Isle of Wight. I'd be quite confident about changing the relevant Isle Of Wight ways to prow:ref , but would not want to mass change all the UK ones.
