[Talk-GB] NaPTAN (stop) import

Just to remind folk, the West Mids volunteered as a pilot area for the
original NapTAN import. We asked that the nodes were NOT tagged as
highway=bus-stop as we wanted to survey them before they got rendered. We
still haven't got round them all! And given the accuracy we're glad we
asked for the "silent" import!  In the meantime there have been so many
changes , many of them major like the regrouping and renumbering of ALL the
bus stops in Birmingham City Centre when all bus routes moved out of the
centre in order to make way for the metro, that the original data is even
less accurate. There have been at least 3 new bus stations in the region
opened since then and I've lost track of the bus routes removed or changed!
In short it's  a MAJOR effort to keep this data maintained in OSM. Not that
it's not worth it -  just that with the current population of active
mappers I can't see us staying on top of this. Anything serious is going to
take a lot of outreach work to enthuse new mappers, and also some
co-ordination with the transport folk - we gave up reporting discrepancies
very quickly because of the ensuing deafening silence

Regards

Brian
