Unfortunately the official standards do balloon. Some of the fields
will not be populated, and some are not very exciting for us.

The letter 'C' should be in Indicator'
The code J517 might be in private code or plate code, not sure - it
isn't used in public facing services.

I suggest we do a first pass where we extract the core information and
then we can do a second pass at some point in the future and get all
the details out of it. I will add a comment to each field in the page
you have constructed to say if I think it is normally populated and if
we should bother with it.
Here is a Stop Point on Tower Bridge Road heading north. Here it is on
The information OSM has for this is just 'highway=bus stop'
NaPTAN has this stuff:
Full Name: The Borough, Abbey Street Tower Bridge Rd (---)
Location: 533405, 179535
Locality: The Borough
Common Name: Abbey Street Tower Bridge Rd
Stop Area: Abbey Street Tower Bridge Rd
Street: TOWER BRIDGE ROAD
Atco Code: 490003035N
Nat Gaz Id: E0034790
Stop Type: BCT - MKD
Admin Area: Greater London
This list doesn't include the NaPTANCode which we should import and
possibly some other minor or blank fields.
The Stop Point is part of a Stop Area together with the stop on the
other side of the road.
The Stop Point is in 'The Borough' which has a bunch of other stops
included and a centre.
Give me a the exact bus stop position for one you would like data for
t I will say what it contains.
