Hi Fredj
If you take information from DIDOK, yes please provide the source. This could make it easier for future editors to see what the state is.
It should also be acceptable to remove the source tag and provide the source in the changeset as the source= tag
Actually the year would already be 2015, as I imported the list for after the next time table change (which is due in December) I need to document this in a better way.

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

Hello
I imported the newest dataset of public transport stops from the BAV (Bundesamt für 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 _______________________________________________ talk-ch mailing list talk-ch@openstreetmap.ch http://lists.openstreetmap.ch/mailman/listinfo/talk-ch
