And physical rehabilitation, dementia care, psychiatric counseling...
the list might be quite a long one.
I'm coming round to the opinion that the different kinds of surgeries
are all just really kinds of what's being proposed in the rather
stronger Clinic_(Medical) proposal. But it is probably wise to
distinguish a dentist from a chiropodist somehow if they might be the
only ones occupying their respective buildings.
I think we should merge everything into Clinic_(Medical), either before
it gets accepted or after. Make that mean anything from a huge
polyclinic covering many disciplines to small doctors' surgeries and
dental practices.
So how to distinguish one sort of treatment or care from another?
Perhaps a merged proposal for "small to medium medical facilities"
should be something like:
amenity=clinic
medical=
emergency=yes|no
where is a semicolon-separated list of values from
{dentist, doctor, chiropodist, physiotherapy, minor_surgery, ...}.
Opticians in the UK are more like high-street shops than medical
facilities. It would feel strange to call an optician a clinic too, even
if the upstairs consulting rooms are all separate and have something of
the doctor's surgery nature. Hmm.

Hi everybody, let me introduce first: I am doing a similar work as openstreetmap does. Actually I wanted to start something like this in 2003, when I didn't have a job and lots of time - but no money to get it up and running. Well, having just ISDN I didn't catch openstreetmap.org and did my own thing. My focus was on sports - such as calculating route-lenghts and the like. In 2003 I bought my first GPSr an started a bloody hack to visualize the tracks. Currently I have two major maps with about 100.000 WPs each that are categorized in terms as area (mountain, forest, in-town, ...) and WP-Types like Roads (gravel, small road, highway, bridge ...), service (Restaurant, cash-dispenser, gas-station), ways (path, fixed path, stairs, ), area (picknick, park...) hospitals ... To make a long story short: How do I get all these into the map? Is there a forum to discuss things? I won't have the time now to re-edit 200.000 WPs, but I would take the time to write a convert routine to make a bulk upload - if it doesn't require editing afterwards. I'd be glad to be a part of the community, and as far as I can tell after a few days of looking around at least 150.000 WPs of my collection are not in openstreetmap.org - yet. Any ideas? P.S.

[OSM-talk] [tagging] Medical centres, clinics, doctors and dentists
What are peoples' thoughts on medical facilities that can't really be
represented as either hospitals or pharmacies? For example small clinics
for minor surgery, doctors (UK: General Practitioners' surgeries) and
dentists? There are a few proposals out there already (still):
http://wiki.openstreetmap.org/index.php/Proposed_features/Clinic_(Medical)
- AFAICT, all those votes are merely opinions :/
- I like this one. Healthcare provision in the UK can be rather...
distributed.
http://wiki.openstreetmap.org/index.php/Proposed_features/GP_Surgery
- "work in progress" since a very long time ago
- It'd be nice if there were an actual tagging proposal here
- medical=doctor and medical=dentist would be my first suggestion; I
might warm this one up myself. However, I'd accept amenity={doctor,
dentist} too.
amenity=pharmacy, dispensing={yes|no}, amenity=hospital, and
emergency={yes|no} were accepted ages ago, so at the very least I'll
tidy up this area of the Wiki tonight. Should I pull in any other pages?
(What sort of tags should we use for land belonging to, say, the NHS and
within the bounds of a hospital proper which doesn't have wards or
clinics on it? For example, there's everything from supply sheds serving
the hospital to nurses' accommodation, playing fields and gardens on one
of the sites 'round here.)

It isn't in a tunnel though - if it was, it would have tunnel=yes. layer=-1 is often used for waterways for a couple of reasons: 1.
