Re: [OSM-talk] Subway Routing in Maps.Me

[Martin Ždila]

Hi Ilya,

Just for the interest, Slovak OSM community has beta-version of public
transport routing. Example (in Slovak only):
https://www.freemap.sk/?map=14/48.133788/17.128243=O=imhd=48.111615/17.101250,48.152917/17.136526
.

Still it is not based on public transport relations (yet) and uses external
API for it (http://imhd.sk/ba/public-transport). The benefit is that it
also uses timetable of the public transport.

Best regards

Hello, same issue here: retagging a single, multi-purpose heavy rail line
(out of tens of similar others) to light rail  (which it is not) so that
one data consumer picks up on it? That is blatant mapping for a renderer,
and was reverted by locals who actually have OTG knowledge (in this case,
yours truly).

Also, not related just to that mass retagging: if you're armchair mapping,
great! But please, do respond to changeset comments - maintaining radio
silence, especially on questions about an unusual edit, is somewhat
suspicious (and in this specific case, it was one of the reasons for a
revert).

Other than that, I like the feature - a lot; didn't have time yet to bring
the local metro up to speed, but it's one of my goals for the new year :)

Thanks for your work and best of luck,
Jan "Piskvor" Martinec

why not real rail as well? E.g. in Berlin it is much more convenient to take a 
normal train from the airport (SXF) to the centre than it is to take a light 
rail train (too many stops). Similarly in Rome, most local trains aren’t light 
rail and you’d miss a lot of connections if ignoring railways.

Ilya, it’s great to see intermodal routing implemented in maps.me.

Still this recent concerted action showed yet another time the problems with 
people editing out of their familiar local context, and I’d like to use the 
opportunity of this thread to point this out and invite other mappers to check 
for similar problems in their area (and fix them).
Some months ago a user with a non-local locale had changed a lot of regional 
railway routes from rail to light rail in “my area”. Problem is, those are real 
railway lines, not light rail. You and some people who follow you have then 
used the presence of (only) light rail routes as indication that also the 
stations should be light rail stations. This led to nice consistency, different 
users mapping different objects (routes and stations) in a consistent way - 
just that it was blatantly wrong.

Please, don’t do it. Do not perform edits that require local knowledge in areas 
where you don’t have this knowledge. Do not assume you can deduct missing data 
from other map data, especially in a field like public transport, where few 
mappers are active, and where bugs and errors might sleep for longer than in 
other fields (this point actually might improve with more people using the 
data, and this is of course a very positive aspect of maps.me using this data 
for routing).

Again, great to see this now implemented in maps.me.

Cheers,
Martin

[OSM-talk] Subway Routing in Maps.Me

[Ilya Zverev]

Hi,

You might have noticed an unusually high attention to public transport mapping 
in OpenStreetMap recently. There was a validator, a big proposal that got 
rejected, and another one that isn't yet. You might have seen subway route 
relations in your city edited, to better conform to the PTv2 schema. Why? What 
was all that for?

Last week we have published MAPS.ME 8.0 for Android and iOS. If you plan a 
route in one of 74 cities, it will suggest using a subway or a light rail 
network. That includes London, Paris, Berlin, Milan, Moscow, Yokohama, Dubai, 
Lima and many others. What I'd like to highlight, is that zero GTFS feeds were 
used for that. All the data comes from OpenStreetMap.

http://www.openstreetmap.org/user/Zverik/diary/43020

This is without doubt the first time somebody has used public transport 
relations from OSM for routing, considering the state of these relations three 
months ago. I see the development of the public transport schemas being tied to 
just rendering, and maybe this would make them better. Who knows, maybe in a 
year even overground routes in OSM could be used for anything other than 
highlighting roads.

I'd like to thank you for discussing the proposal and mapping, and to ask you 
for help mapping the rest of the cities. Especially the United States and asian 
countries. I am willing to explain anything that is unclear, possibly improving 
the Metro Mapping page.

Thanks,
Ilya
