b) splitting the pages down into smaller components - eg railways,
bus stops, train services, train stations, etc. Whilst it's good to
have an overall conceptual model, I think most mappers will be more
interested in understanding how to tag at a feature level.
Umm.. I think it is important to have a page for the conceptual
model and then when we are happy with it, we introduce it into the
other articles in the context of that transport mode. A description
of a Stop Place for a drag-lift will be pretty different from that
of an airport, but I am keen that there is a consistency across
modes from a programming and tagging perspective.
I think I more-or-less agree. I'm mainly just keen that we keep the
discussion embedded in the context of actual usage (with plenty of
real-life examples) rather than being too abstract.
Ok, I completely agree that someone who wants to model a railway
station should have to look no further that the train page (or railway
station page) and should gets lots of great examples of how to model
stations (and nothing about drag-lifts!).
However... I also want there to be a good robust general purpose model
behind it (what I call the Stop Place) and that also needs a page that
the developers look at when wondering how to model the world
efficiently (including drag-lifts and Manchester Airport!).
I think we should also remove the redirect from http://wiki.openstreetmap.org/wiki/Key:public_transport
and turn that into a standard Key page (with the KeyDescription
infobox) documenting existing and proposed usage of the key.
Likewise, it'd be useful to have the relevant tag and key pages for
all the other tags and keys that are in use or proposed.
It is certainly not appropriate for it to redirect to a user page.
For now I have redirected it to the Transit article until someone
fancies adding some content, however.... I am not clear if we even
want a key of that title, should we not standarise on Transit rather
than public transport. The proposed use of the tag is something I
would prefer to call stop_place anyway.
I agree that whether we need the key or not is unclear. However,
since there's at least some usages of it currently, I think it's
worth documenting what the existing practice is at least (same for
other tags with significant usage).
fine by me
This reminds me - I think it'd be worth encouraging people here to
share links to OSM for public transport stops/routes/etc that
they've mapped, for feedback and discussion. I did this a while back
on the discussion page for the unified_stoparea proposal (see http://wiki.openstreetmap.org/wiki/Talk:Proposed_features/unified_stoparea)
In this spirit, here's what I've mostly done so far:
Oxford Road train station (http://www.openstreetmap.org/browse/relation/78910
)
- mapped the platforms as areas (railway=platform, role=platform)
- mapped all the tracks, and the stopping points (role=halt) with
one of them marked as the 'main' one with railway=station and a name
tag.
- station building outline (building=yes, no role)
- footbridge and steps (not part of the relation - wasn't sure
whether they should be?)
Have started to map the tram system in Manchester as two separate
tracks (http://osm.org/go/evgo1FaS--) though this is complicated by
the sharing of ways with the highway, and the current part-closure
of the system for track replacement.
Mapping UK tram system routes as relations (see
http://wiki.openstreetmap.org/wiki/United_Kingdom_Trams)
Mapping UK 'minor railway' routes as relations (see
http://wiki.openstreetmap.org/wiki/WikiProject_United_Kingdom_Independent_and_minor_railways)
I suggest we have a list of 'examples of good practice' associated
with each page. the Tram page should like to good examples of Tram
modelling and also all the tram related projects and email list around
the world. Similarly the Train / Railway page would do the same for
trains. I suggest the Stop Place page might give some examples of a
few of each sort of Stop Place, including a real monster multi-modal
interchange (JFK, Heathrow or Schipol).
Regards,
Peter
Would welcome comments on any of those - and would love to see which
bits of the map other people are working on!
