I am surprised to hear that the current NaPTAN data (which is continually updated) has errors in it – and I wonder therefore if the problem may lie in the updating of NaPTAN data in OSM. The original upload of NaPTAN to OSM was done about five years ago – and therefore it would not be surprising to find stops missing or ones that have moved in the meantime.
I believe that Brighton & Hove are good at maintaining the data in NaPTAN – but their idea of precision and yours may differ (as for public transport information we can be tolerant of slightly imprecise locations). So you should use the latest version of NaPTAN and I can supply a copy in XML or CSV format if that would help.

The data is based on submissions from each local authority and I think the quality varies. I checked about a hundred stops and ended up surveying a couple of thousand bus stops because the quality was so poor. Locations were missing, in hopelessly wrong places and the meta data was often wrong. The local authorities here don't seem to believe in sharing data so you may have a completely different result. If you plan to survey some or all of the stops then using NaPTAN data as a hint to find them is useful. I suggest you check out a few first to assess the quality before any import. You should email talk-gb and possibly the imports ml to see what people think, this ml doesn't have a wide audience Cheers, Chris On 30 June 2015 10:43:20 GMT+01:00, Stephen Dawkins <elfa...@elfarto.com> wrote: Hi I was just starting to map the bus routes in Brighton, UK, when I noticed that it's missing a whole bunch of bus stops. Is the any objection to bulk importing either the NaPTAN data to fill in all the missing stops? Reading the mailing lists, it seems the NaPTAN data is not ideal, but surely it's better than having no data at all. For stops that already exist, I'd like to enhance them with their NaPTAN identifiers, but I won't attempt to move them (the assumption being the existing data is probably more accurate). I'm fairly new to OSM and was wondering if there is any issue in doing this?
