Re: [Talk-transit] NaPTAN Merging Guidelines
Bryce NaPTAN does not allow the character / to be part of a commonname as NaPTAN rules (not fully adhered to by TfL or LBSL) do not allow composite commonnames. Underground station entrances are included in NaPTAN data ... they are part of the 490 area data (whereas the stations themselves are in a national dataset prefixed 940) Roger -Original Message- From: talk-transit-boun...@openstreetmap.org [mailto:talk-transit-boun...@openstreetmap.org] On Behalf Of Bryce McKinlay Sent: 18 August 2009 01:08 To: Public transport/transit/shared taxi related topics Subject: Re: [Talk-transit] NaPTAN Merging Guidelines Thank you very much for your efforts on this, Thomas, and everyone else involved - I've been waiting for the London import for a while, and it's fantastic to see this data in OSM!

TfL refers to this as Conduit Street / Saville Row, so it seems the / characters are going missing somewhere? The data in NaPTAN does not include the '/' actually, probably because of the work being done to standardise stop naming across the UK in NaPTAN. In particular to discourage stop naming of the form 'street/ cross street' and the use of some characters including /. In this case the slash has gone but the cross street naming remains. Also, I'm curious whether, in addition to the bus stop data, NaPTAN contains precise locations for Underground station exits, and if so, whether there is any plan to import these?

This level of precision does become significant when producing walking maps/directions... Yes there are entrances in NaPTAN. For example there are 8 entrances given for Oxford Street Underground station. There are also platforms information, but no indication about which platform they relate to. Can I suggest we complete the import of bus stops import into OSM first and then go back for another trawl through the data and get more detail?
