[OSM-talk] All the subway systems in the world

[Ilya Zverev]

Hi,

I have made a script that parses and validates subway systems. It prints the number of subway lines and stations that an automated system can extract from the OpenStreetMap data. See the latest report here (these are updated manually for now):

http://osmz.ru/subways/

It is still in beta: it doesn't use networks and omits many non-european cities. We plan to employ it for maps.me, so it would be the first app that does world-wide subway routing using only OSM data. To make tagging subway systems uniform and usable, I've compiled a list of practices on this page:

https://wiki.openstreetmap.org/wiki/Proposed_features/Metro_Mapping

Some questions are answered on the Talk page there. Next week I'll open a voting, so that tagging schema could be made official. The validator of course expects that kind of tagging, though it allows for some omissions.
