Yes. For info, stations are regarded as “national” and so have their own 910 prefix. So 9100LHONSEA is Leigh-on-sea (OK, it’s not in London but that’s the one I know). The alpha code on the end is a match to the rail industry TIPLOC codes, which throws up some oddities (such as London Victoria and London Bridge having two TIPLOCs each, and Clapham Junction having four).
Metro stations are also regarded as national, and so have 940 prefixes. In the cases I mentioned before, 9400ZZLUBNK is Bank, and 9400ZZLUTWH is Tower Hill. In both rail and metro cases, these codes represent the entire station. Then, each rail station or metro station has one or more entrances. These, for historical reasons, are always defined locally and have local codes. So they have the local prefix (490 for London) instead of the national prefix, but use the same identifier for the station. There is then a numbered suffix to distinguish between different entrances, although Bank has so many that it needs alpha as well. So: * 4900ZZLUBNK7 is Bank Station, Entrance 9, on the corner of Threadneedle Street (there isn’t necessarily any direct correlation between the suffix and the entrance number) * 4900ZZLUOXC7 is Oxford Circus, Entrance 7, on Argyll Street * etc The final oddity is that there is a hierarchy. So rail stations can contain metro stations, but not the other way around. But each different entity is expected to have its own entrances. So at Blackfriars, for example, the rail station has two entrances, north and south, and the nominal “entrance” to the underground is actually set on the gateline inside the station building. So there are some things to be aware of, but positionally the entrances are all in the right places (more or less) and you can get a “big bang” from the NaPTAN data even if you later on wish to refine the entrances by survey.

The tube entrances all begin 4909ZZLU followed by a three letter code for the station plus a digit to distinguish between different entrances. For example, 4909ZZLUBNK0 would be an entrance to Bank, while 4900ZZLUTWH0 would be Tower Hill. While these do not give you accessibility information, they are all maintained by TfL and should give you accurate positional information.

We have something UK wide, but doing it a local way makes a lot of sense (and easier to complete). Happy to do this "fix the tube network" thing over a few weekends (After the General Election that is). cheers, Derick On Thu, 4 May 2017, Bjoern Hassler wrote: Dear Grant, dear all, thanks for putting on the meeting, and thanks for the sponsored pizza! Good meeting last night, and god to have met you all. Following up on the "Missing Maps London" idea, I thought we could may do some "map challenges" that look at specific things that need work. It might be a nice community building activity, and provide some continuity between meetings? As an experiment, I've formulated one such challenges here https://wiki.openstreetmap.org/wiki/London_public_transport_tagging_scheme/Map_Challenges and added images / interactive maps / help for new mappers. See what you think and let me know whether there's interest. Results could be announced at the next meeting?

We'd love for you to come along: https://www.meetup.com/OpenStreetMap-Q-A-Meetup/events/239366249/ New to OpenStreetMap and want to learn more or need some help getting started? Already mapping or using OSM and have any Questions or Challenges or want to see what others are up to? This is the event for you. We already have 3 great speakers lined up for the evening: * Andy Allan - OpenCycleMap / Thunderforest * Astrid Thorseth - Missing Maps * Derick Rethans - London Mapper We have a great venue (bias, I work there), there will be pizza and soft drinks provided. I'd love to hear any suggestions on how we could improve the event or what works elsewhere.
