Hello,
Should the source be updated as well?
The value is:
 "Bundesamt f?r Verkehr (BAV), DIDOK 2009"
should I update it to:
 "Bundesamt f?r Verkehr (BAV), DIDOK 2014" ?
Thanks,
fredj

Hello
I imported the newest dataset of public transport stops from the BAV
(Bundesamt f?r Verkehr), known as DIDOK list, into our comparison tool
at didok.osm.ch
I had a look at the stops where DIDOK and OSM disagree the most in
location (the stops where we have the largest distance between the OSM
coordinates and the DIDOK coordinates)
http://didok.osm.ch/#sw:9:46.903369:8.316650
And I made a few corrections to OSM data. Mostly there were issues with
OSM having a wrong uic_ref number attached to the stop.
For a few stops it seems the DIDOK data has improved, and we still have
the old DIDOK data which was imported in 2009 and was a few kilometres
off. But it seems there is no big potential for automated edits, this is
best done manually. I have found some stops where the new location is at
least as questionable as the old one (example
http://didok.osm.ch/#sc:14:47.491631:8.254766 The new DIDOK coordinates
are on the SW end of the black line. But to me it looks like
"Ennetturgi" is rather on the NE end)
Over all I think DIDOK has improved a bit, but there are still lots of
funny errors in it. For example here:
http://didok.osm.ch/#sc:14:47.491631:8.254766 they mixed up Gonten and
Gontenbad :) Too bad we couldn't motivate them to use OSM to check their
data.
I will follow up with one or two other DIDOK related topics in the next
few weeks. In the mean time please keep using our public transport check
tool. There are still lots of unchecked bus stops
(http://didok.osm.ch/#sc:14:47.491631:8.254766 the red circles) which
are potentially totally wrong data from DIDOK.
Have a nice week
Michael
