Re: [Talk-transit] NaPTAN Merging Guidelines

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)

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!

I have one bug to report: Is it possible that special characters are
being dropped from the stop names during the import? For example:

 node id=469789137 lat=51.5122005 lon=-0.1420652 version=1
changeset=2177128 user=NaPTAN uid=104459 visible=true
timestamp=2009-08-17T13:40:06Z
tag k=name v=Conduit Street  Saville Row/
tag k=naptan:CommonName v=Conduit Street  Saville Row/
...

TfL refers to this as Conduit Street / Saville Row, so it seems the
/ characters are going missing somewhere?

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? OSM often contains only one
node for stations that have multiple exits, and in some cases the node
is ambiguously placed such that it isn't clear which street (or which
side of the street) an exit is on. This level of precision does become
significant when producing walking maps/directions...

 Now that we're importing the data, we really need to get our

 It really needs to be tidied and beaten into a useful document before
 we let more people loose with the data.

tag k=naptan:CommonName v=Conduit Street  Saville Row/
 ...

 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? OSM often contains only one
 node for stations that have multiple exits, and in some cases the node
 is ambiguously placed such that it isn't clear which street (or which
 side of the street) an exit is on. 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?
