While creating this map by hand was a fun exercise, I never came around to maintaining it and keeping it up to date – which is arguably the most valuable part of such a project. Fortunately, the late Alexey Valikov aka highsource picked up on the idea and maintained his Verbundkarte at highsource/verbundkarte.
What is this? – I could not find a decent machine-readable(!) map of all transit authorities in Germany (nb, the German Verkehrsverbund system is a rather unique beast, see Pucher and Kurth 1995 for reference)
While Wikimedia Commons has a pixel-based map, I wanted something GeoJSONy that can be used with Leaflet or something like that.
The intelligent approach would have been to supply the Wikidata object of each Verbund with the necessary information to automatically pull all areas of all Verbünde out of there.
Sadly I have no clue how to do this.
So I took the manual approach and
- downloaded the administrative districts
- imported the resulting GeoJSON into QGIS and saved the layer as a Shapefile
- manually merged all districts if they belong to one and only one Verbund
- added additional columns for districts without an associated Verkehrsverbund and to discriminate Verbünde with and without Schienenpersonennahverkehrsintegration (you've got to love German, huh?)
I'd like the data to include URLs to GTFS feeds (if available) and EFA and/or HAFAS endpoints (dito). Also, some Verbünde more or less cut districts in half, which also needs to be taken care of
Do it!
