This sounds reasonable. Round here (Oxford), there are three types of on-the-ground signs for the local cycle network: Numbered signs that appear to meet the Traffic Signs Regulations and General Directions 2002 (TSRGD 2002) - I think these have only been used where the local network follows a route also on the national network, so they're all double-labeled, EG: http://cycle.st/p34892 Numbered Oxford Cycle Network signs, EG: http://cycle.st/p34893 Unnumbered TSRGD 2002 signs, with just the route's destination on them, EG: http://cycle.st/p34890 Obviously, the first two are enough to justify lcn_ref= and in general the last gets at least lcn=yes. However, knowing the numbering scheme of the network it's possible to infer the lcn_ref even when it's not on the sign: Route 1 (which numbered signposts) follows NCN 51 roughly North-South to the city centre, then there are 8 more spokes, numbered clockwise, and finally 10 is the ring-road cyclepath. This used to be displayed as a poster on information boards around the city, and was the source of of the numbering when I've used lcn_ref= for unnumbered routes in the past. I don't think the poster is on display any more, but that doesn't mean it's bad data! - Cycle networks that are not significantly verifiable on the ground, but are proposed for official adoption and are under active discussion with the transport authority, are tagged as lcn=proposed. I'm much more nervous about this - OSM is not the place for planning data. I think =proposed should only be used in the case SomeoneElse mentions.

This highlighted to me a general problem with the scheme. For rendering the scheme is perfect - drawing a bus stop or a cycle lane on one side of a road is exactly what is needed. However, for routing you need to know which direction a bike may travel along a cycle lane, or which direction buses from a stop will be heading. To derive a travelling direction from the Left/Right terms a routing engine is usually going to need to know the local rule of the road - do we just leave this to the routing engine to factor in (needing to work out where in the world it is), or is there another simple solution I've missed.

This sounds great until you start listening to Cyclox member opinions (see that post refered to above for example) when you find there's a subtle conflict with... * OSM who only want facts in the database, not subjective opinions. I'm not sure what would go into making a really useful local cycling map, but I think at some point it's going to need some subjective tagging. When this has cropped up before some people have said we just need to add lots of factual tags and the rest can be calculated from that. This is good theory, but imagine how hard it would be to render the current map if instead of highway=motorway we instead had car=yes, lanes=3, oneway=yes, hard_shoulder=yes, foot=no, bicycle=no, horse=no, learner_driver=no, etc! highway=motorway is great for a traditional road map, because the classification of roads for motorvehicles by officialdom is generally quite sensible. Sadly the same is not true of classification for cycling.

I'd probably not use the colours they've suggested, but that seems to be the first comment from everyone who sees it. I particularly like the healthy disregard it has for official cycle facilities - cycle lanes/etc are simply taken into account when assessing the level of any road, rather than being depicted on the map themselves. The problem is, and remains, the subjectivity - we can probably get good agreement in and around Oxford on what roads are what level, but if someone else tries to tag somewhere else, they might have a different baseline. The stuff you've added to the discussion page of the wiki page you refer to above is a good start to helping everyone use the same baseline, so lets keep working in that direction! s ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Placing an Area's Nodes near the adjacent Way's nodes helps make the map easier to maintain. I will often abut adjacent areas that are separated only by something thin and make their nodes share, however. Putting the other side of the argument, as Andrew I'm sure knew I would: A road is represented by a single way. Although the way has zero width in the database, it represents the whole width of the carriageway (pavement) and well as the pavement (sidewalk). If a minor road meets a more important way at a T-junction, we do not put the last node where the minor road ends, instead we extend it to the centre of the more important one. In the same way, if an area comes right up to the edge of a road (including its pavement, etc), we should extend the area to use the same defining nodes. If we do not do this, we have an undefined space between the area and the road. This undefined space is of variable width and, without knowing how every renderer is going to treat the highway, there is no way of knowing if it will appear or not, unless it is arterially small (aka 0!). There is some merit to the argument that seperation would help with routing. We could have a convention that if an area is accessible from any point on the highway they should share segments, but if that's not the case (there's a fence between, for example) they should be seperated. While I can see how this would work, it feels like an ugly hack. It's not my itch, but there's got to be a better way of expressing the boundary between highway and area - I guess with a relation. Rectilinear buildings in particular should be kept rectilinear: there's no excuse for trapezoidal buildings with the new extrusion stuff now in JOSM :) I agree with that as a potential stumbling block, and was concerned about this until I actually started mapping buildings. In practice, the resolution of accuracy in OSM is such that you can make a fair representation of the shape of the building and still share nodes with the highway it abuts. However, rivers are Interesting: quite often an Area whose edge is defined by a river may change over time as the river meanders... In that case, it probably does make sense to abut a Way to an Area.

I cycle a section of the Thames Path on my daily commute that comes into the latter category, and apart from the puddles tending to get larger each time it rains, it's just as good as the asphalt sections. The cycle paths in the New Forest are somewhere in between these two categories - while the Thames Path one could reasonably be labeled surface=dirt, the New Forest ones are definitely gravel, but it's well compacted and many of them will be cycled on by hundreds of people a week during the summer. http://www.geograph.org.uk/photo/35904 http://www.geograph.org.uk/photo/388784 http://www.geograph.org.uk/photo/35915 http://www.geograph.org.uk/photo/87018 http://www.geograph.org.uk/photo/381057 http://en.wikipedia.org/wiki/Image:New_Forest_Cycle_path.jpg From these photos it can be seen that there's quite a variety even within the National Park and depending on your style of bike you might want to avoid some or all of them. s ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk

The expected traditional solution to this is toothpaste stripes - the colours of each route running alongside each other, but I don't know of a renderer that can do this automatically. I'd also like a quick and easy way to render printable streetmaps with street and point of interest indexes refering to an overlaid grid.

Seriously, this feels like the OSM way, and therefore is right. 1) Existing tags are already dirty with respect to units - they can, and *do* contain mixed units. 2) This is analogous to the language keyspace - the unspecified key contains the local what's on the ground data, but specific languages are in the approriate key.

Hi Gerv - I've snipped lots below - if I haven't commented on any part, I pretty much agree. On Mon, Jan 21, 2008 at 06:36:48PM +, Gervase Markham wrote: Narrow sections are denoted by maxwidth. One narrowboat (just over 7 feet) is given as 2.5m. Two boats is 5m. It's not necessary to mark a two-boat width restriction for bridge holes, which are implied narrow. I don't mind there being an assumption that unspecified units are metres, but the UK canals are done in feet, and if I'm going to put any dimensions in, it'll be in feet, so I'd need a way to specify that's what I'd done. boat=private is used for private parts of the canal. I see no reason not to use access=private, myself, since the towpath can have a seperate access tag. The lock=yes way(s) takes various lock-related information, including: - the lock name, if it has one, with name=foo. since this way is also part of the waterway, name= is already in use for the name of the waterway - we need something else for the lock names. A flight of locks with a unifying name (e.g. Hatton Locks) is denoted with a node placed in an appropriately central position with new tag value place=lock_flight and name=name. Better to group them with a relation, I'd have thought. Moorings Mooring info should be attached to the relevant stretch of towpath [...] On UK canals, mooring is generally allowed everywhere, except where explicity signed otherwise - do we need a tag for mooring-not-allowed?
