Google take a feed of NaPTAN stop point data – and hence something like Piccadilly Gardens in Manchester is a mass of them.
NaPTAN does have the facility to hold stoparea data – but the data is not fully populated (as it is not useful when presenting journey itineraries to the public – or local information systems have their own way of creating such stopareas on the fly without requiring the data to be held explicitly in NaPTAN records). We did experiment with using stopareas with Google – but the need to link the data to Google Transit for specific journey planning meant that you were told to catch a bus at, say, Piccadilly Gardens – rather than from stop 10 at Piccadilly Gardens ... and for itineraries to be useful, the “stop 10” bit is quite important!

Which rendering view are you using? for the main Mapnik view on openstreetmap there are no bus stops until one zooms in to zoom 17 at which point there are certainly lots of bus stops (accesses). It's good to see that we're not the only ones with this problem, though. Google Maps seems to render a huge number of bus stops now that they've imported public transit data for the uk. See http://www.google.com/maps?f=q <http://www.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=manchester,+uk&sll=37.579413,-95.712891&sspn=30.958234,75.234375&ie=UTF8&ll=53.479797,-2.239387&spn=0.005708,0.018368&z=16> &source=s_q&hl=en&geocode=&q=manchester,+uk&sll=37.579413,-95.712891&sspn=30.958234,75.234375&ie=UTF8&ll=53.479797,-2.239387&spn=0.005708,0.018368&z=16 for instance. That view contains two bus stations (by Piccadilly Gardens and the coach station by Chorlton Street), and yet both a rendered simply as a mass of access points, rather than a singular named node (which would be more useful). So if we can solve this problem, we'll be one up on Google! :-) Frankie P.S It's good to see that platforms are now rendering on Mapnik (see http://www.openstreetmap.org/?lat=53.477811 <http://www.openstreetmap.org/?lat=53.477811&lon=-2.243247&zoom=18&layers=B000FTF> &lon=-2.243247&zoom=18&layers=B000FTF), however I note that it's not coping well with platforms that are areas (as closed ways with area=yes). Having blue arrows on the tramlines that are marked with oneway=yes is also a little odd. -- Frankie Roberto Experience Designer, Rattle 0114 2706977 http://www.rattlecentral.com Sent from Manchester, Greater Manchester, United Kingdom
