If you find any NaPTAN data that doesn't match the real stops I suggest you 
drop an email to the council transport team. It might help them improve the 
next pass of data. I did that with both Hull and East Yorks when they were 
imported originally about 10 years ago. After some skepticism they did use my 
info.

That's always an issue with imported data, the tag naptan:verified helps 
in this respect.


In the Lancashire dataset there are HAR (Hail and Ride) and  CUS 
(Customary) stops which I think are virtual - there is no mark on the 
ground, these will not be imported, so I think we have the main 
variations covered.

To clarify, I mean stops marked as active which are no longer 
physically there (implying the NaPTAN record is outdated).

No objections from me obviously!

I like that you included handling for records marked as deleted in NaPTAN.
Not something I considered until it was brought up after my import.

It might be worth mentioning handling for stops present in NaPTAN which no
longer exist. I've been following the original import surveying advice (
https://wiki.openstreetmap.org/wiki/NaPTAN/Surveying_and_Merging_NaPTAN_and_OSM_data)
to remove the bus stop tags and add `physically_present=no` (example
https://www.openstreetmap.org/changeset/72305337). It makes sense to me to
do this rather than delete the nodes so that if re-imports take place they
can be matched and the stops won't be accidentally re-added if they're
still not updated in NaPTAN.

Along those lines, you may want to update the overpass conflation query to
include such features:

> [out:xml][timeout:25][bbox:{{bbox}}]; (
> node["public_transport"="platform"]; node["highway"="bus_stop"];
> node["naptan:AtcoCode"]; ); (._;>;); out meta;

 We could perhaps update much of the wiki pages to reflect that they are
historical from the original import and establish a new page for best
practises dealing with NaPTAN data in OSM.

[Talk-GB] NaPTAN/Lancashire import

[Tony Shield]

Following on from SilentSpike's import of NaPTAN/Aberdeen I am planning 
to perform a similar import for Lancashire.


I've created a wiki page 
https://wiki.openstreetmap.org/wiki/NaPTAN/Lancashire which I have coped 
from SilentSpike Aberdeen and changed the areas, also slightly altered 
the process to use csv files.


I have performed several dry runs, there are approx 8,000 bus stops in 
Lancashire with about 4400 reported by overpass-turbo.


Importing on a town by town basis is the plan.

Comments please.
