NaPTAN

Every UK railway station, coach terminus, airport, ferry terminal, bus stop, taxi rank or other place where public transport can be joined or left is allocated a unique NaPTAN identifier.

The ability to identify and locate stops in relation to topography, both consistently and economically, is fundamental to modern computer based systems that provide passenger information and manage public transport networks.

NaPTAN stop points have a number of text descriptor elements associated with them: not just a name, but also additional labels and distinguishing identifiers that will help users to recognise them.

Every NaPTAN point includes geospatial coordinates specified in Ordnance Survey National Grid format, and as WGS84 latitude and longitude pairs where these are provided by local authorities.

The National Public Transport Gazetteer is closely associated with the NaPTAN dataset and contains details of every City, Town, Village, suburb in Great Britain (i.e., UK but not including Northern Ireland).
