 There is already route=piste relations (the colors on the link provided).
 This is something else.


what kind of objects do you propose would be grouped in these site
relations, just the nordic piste or also connected services, hotels,
etc.? I guess you want to group linear features (piste) with areas and
points (hotels, parkings, restaurants,...)? In case the answer to the
latter question is yes a site relation might indeed be appropriate.
Alternatively you could suggest a new tag for belonging to resort
foo, or maybe even reuse an established key (e.g. network).

I think relations are not applicable for this case. To me it seems as if
you want to put everything from inside a village in one relation, because
they are all in that village. That's just not how OSM works. Either that
resort has borders, and you draw them, or the ski lifts and piste have the
same operator and you put operator=* on everything that is operated by
them.

Again, relations are not
categories.http://wiki.openstreetmap.org/wiki/Relations_are_not_categories

if they don't have a common operator and the resort doesn't have a

cannot map them? Btw.: the OP is asking for nordic pistes, so there
won't necessarily be any lifts.

Why not resort=L'Auberson on all nordic pistes? Yvecai says it's error

Re: [Tagging] [Imports] RFC - Adding UN LOCODE tags to OSM

Doug,

Since you're pretty knowledgable about this topic, it'd probably also be
good if you could flesh out the harbor:LOCODE page on the wiki (
http://wiki.openstreetmap.org/wiki/Key:harbour:LOCODE).  It's part of this
big harbour proposal: wiki.openstreetmap.org/wiki/Proposed_features/Harbour

Cheers, Brad

PS--one side question: shouldn't LOCODE be locode (that is, lowercase)?
that's how iata and icao are handled for aerodromes...

On Sun, Feb 3, 2013 at 11:47 AM, doug.fra...@tarisoga.com wrote:

 Followup to my post:
 I am here at the London OSM Hack Weekend and spoke to someone who
 explained to me the larger issues and questions about importing / updating
 metadata like LOCODEs that can't be surveyed - i.e. data where managing the
 process of keeping it current may be troublesome.
 I agree with everything he explained and so now I don't think updating the
 LOCODEs that are present, etc would be the best idea.  Letting the existing
 tags die off sounds like the best idea.
 But locodes are assigned to harbours and they are surveyable, can be
 verified by the public, all that sort of thing.  So the UN list could be
 used to update or verify that cities have appropriate harbour tags
 associated with them.  IIRC, Long Beach (or LA) was one test case I looked
 at and it didn't have a tag that i'd expected.
 So now my idea is to check the harbour tags against the UN data (this
 could also be done for rail stations) and then determine how much data is
 missing and what ought to be improved.
 A related idea is that port terminals (for commercial shipping) are
 becoming prominent features (e.g. they are getting their own locodes) and
 perhaps a new tag harbour:terminal (like harbour:pier) could be created for
 handling this data.  Container terminals are physical features and won't
 arbitrarily change, so they aren't metadata like LOCODEs.
 If anyone has any feedback, I'd appreciate it.  I don't plan on doing
 anything until I fully understand the details of all this, so I can write
 it all up, etc.

 [Imports] RFC - Adding UN LOCODE tags to OSM writes:

 Hi everyone,
 This is a duplicate of a email I sent to the Tagging list:
 The company I work for deals with shipping ports, UN LOCODEs, and
 shipping schedules - I had hoped to use OSM to correlate geographical type
 info and LOCODEs.  The problem has become messier than I ever thought, and
 unfortunately OSM does not have much in the way of LOCODE related data.
 At this point, we have a well maintained list of LOCODEs and other such
 data that I keep track with the UN list as it is updated.  So I thought
 it'd be useful to put all that into OSM and clean up the handful of LOCODE
 tags that I have seen in OSM.  This list also includes IATA data and some
 other port type info - everything has been gleaned from public data sources
 like the UN, so I'm sure there are no license related issues.  I'm also
 confident of the accuracy since I'm the one responsible for maintaining the
 data.
 I will write up a feature proposal on the wiki to outline the details,
 but first I wanted to see if there were any comments or advice people might
 have.  I do plan to automate the updates - none of this is map data per se,
 but just tags, so I assume there won't be any real complications. So I will
 read all about the guidelines around automation.
 The questions I had are:
 1) the UN provides geographical coordinates of these LOCODEs, typically
 the city center.  Is there any standard that OSM adheres to regarding the
 location of cities?  Anyone have any pointers to info I should read?
 2) alternative place names - the UN provides some data and we have data
 from other sources.  The data is good, but is there any consensus on this
 topic about how OSM ought to operate?
 3) locations/cities not in OSM at all - adding these in is a separate
 task entirely so I will leave that till I understand OSM better.  But if
 someone could point me in the right direction, that'd be great.
 Thanks

Janko,  to group a bunch of elements into a relation or add same a tag 
to all these elements is not quite the same. A relation carry a meaning 
(type), while with all these tags, It's seems to me just a collection 
that you can find with a query :)
(Actually, we all know that both are technically feasible, no need to 
fill up the history for testing ;-).


Quoting the wiki page you linked:
Grouping relations really only make sense if the grouping is neither 
geographical (as discussed above) nor exclusive ...


Exclusive you take care of with a semicolon, why not.

For the geography, I think of this 'resorts' as a kind of geography by 
itself, after all (not sure I use the term properly, pretty sure I 
don't, in fact).
When I go skiing to 'Le Risoux', I don't speak about the forest 
(http://fr.wikipedia.org/wiki/For%C3%AAt_du_Risoux), nor the mountain 
(http://fr.wikipedia.org/wiki/Mont_Risoux), but rather of a bunch of 
pistes, along with the 3 entry points and their cabin where people drink 
tea selling you tickets, and so ...


Now, my 'rationale' :
As I go skiing here and there for mapping, I more than often go to place 
I don't know yet. I check websites and forums about snow and skiing and 
resorts and try to find out how I go there on low-res scanned maps. It 
took me quite some icy road to find 'Le Risoux', and I first found these 
pistes by the longest road. I'd like to be able to find it more easily.


When I look for 'La Seigne' in nominatim, I found 'Locality La Seigne, 
Les Hôpitaux-Vieux, Doyenné du Haut-Doubs forestier, Doubs, Freie 
Grafschaft, France

Although geographicality close, it's not the same as the  'Resort La

general tagging guidelines say: no abbreviations, no capitalization,
underscores instead of spaces

this would mean the key should be:
united_nations_code_for_trade_and_transport_locations  ;-)

but this is not very handy. There are a few exceptions to the general

united_nations_code_for_trade_and_transport_locations looks absurd

You may want to read this wiki page:
http://wiki.openstreetmap.org/wiki/Semi-colon_value_separator

It gives you a lot of reasons not to use semicolon delimited values. But
admittedly it doesn't give relations as an alternative.

While I also see that skiing resorts are kind of geographically and
therefore could be expressed as an area instead of a relation, I'm having
trouble with how anyone would be able to determine where to put that border.
They are, for the part I know, mostly defined by the pistes/lifts/amenities
that belong to it instead of  a border on the map. And I'm somehow not
comfortable with an area which borders are defined by a mapper at his own
discretion instead of a survey-able feature on the ground.

My favorite therefore is still a relation, but I'm cutting out of this
argument now, as skiing definitely isn't my area of expertise.

Only the design outline has thus far been discussed. In summary, any

which will overlay an invisible button over that position in the

I would like to disagree partly here.
You're right: a relation should carry a meaning, but if all meaning is 
these piste routes belong to the resort X, then a tag resort:name=X 
would carry exactly the same meaning.
IMHO to make sense out of a relation here, there has to be more meaning 
due to the relation, like e.g. the office of the resort (if it's 
organized centrally somehow), information signs with maps of this 
resort, a common website for the resort and the like.

This way it's more feasible to use a relation for a ski resort.

The tag resort=X only is not a good argument IMHO, as with that you 
would get the very same result by querying all piste routes tagged with 
resort=X by grep from a planet or using overpass.


The issue that one route may belong to more than one resort is a 
slightly better argument, but there was an overpass solution for that as 
well in an earlier mail.

Quoting the wiki page you linked:

but you could even describe it by the resort Le Risoux roughly 
at/around Mont Risoux which could be translated to a nice overpass 
query using a bbox around Mont Risoux (or a around statement) and the 
resort='Le Risoux' as a filter.


IMHO you should keep in mind what belongs to the resort. I'm not 
skiing, but I guess, there are

- the pistes
- the lifts to transport people uphill again
- signposts with hints about routes, probably difficulties...
- probably lot more.

If you want to go for a relation, think about how to tie that together, 
and why it's useful to put that into a relation.
Relation is not Collection. The verb of relation is to relate to 
[each other].
How does the bus stop relate to a street segment? they are related by a 
bus route where the bus uses that street to serve that bus stop.

For a ski resort this might be something like:
- lifts and the like have the role transport_upwards
- pists and the like have the role piste
- the resort as a whole might have a fee=yes if not the single pistes 
have to be paid but you can pay one bill for the whole resort


I'm sure there's more which could be incorporated, but find reasons for 
the relation, and what value the relational concept adds to the tagging 
solution alone.

There is always an overpass query for every need :)

Anyway, these site=piste relation members would simply be related by ...

Minimal tagging would be:
 type=site
 site=piste
 piste:type=nordic

or

 type=site
 site=piste
 piste:type=downhill

Then, optionnally, name, operator, url.

Members would be the ways described in the pistemap tagging scheme, and 
relations route=piste or route=ski.


I'm not sure pistes ways or relation should be given the role 'piste' as 
it is implicit. Same for upward lifts :)
The only role that came to mind are the role 'entrance', 'link' (to 
another site),'perimeter' (if avail.).



I came here about this idea when I was shown this: 
http://taginfo.openstreetmap.org/keys/piste%3Aamenity#values
Maybe these cafes, shelters, ... could be members of the site relation, 
maybe not, but there is apparently a need here to link them to the 
nearby pistes.

aren't there resorts which offer both, alpine and nordic pistes?

by looking at what wikipedia writes about resorts in various languages
(en,de,fr) it seems as if the piste is more an extra for one or more
hotels, and that it might actually be the hotels which constitute the
main part of the resort. http://fr.wikipedia.org/wiki/Resort

Martin : that's where the type 'site' make sense, it could either be a resort 
or a 'domaine skiable'.

For nordic and downhill, two sites or a semicolon ? That is the question.

IMHO put the piste:type on the route relations and put those route relations 
into a site relation (or group with tags) but don't repeat the piste:type on 
the grouped object

[Tagging] Re : Re : Re : Ski resort (once again)

2013-02-04 Thread yve...@gmail.com
Remains one question, site=piste or site=ski ?
The former is consistent with pistemap tagging, the other easiest to find in 
the wiki.
The rationale about route=piste covering also snowshoeing doesn't really apply 
here. Is there sites dedicated to this practice only ?
