[Tagging] Precisions about tourism=chalet

2016-03-30 Thread sly (sylvain letuffe)
Current tag page is here :
http://wiki.openstreetmap.org/wiki/Tag:tourism%3Dchalet

My questions copied from talk page :
As a non native english speaker, I have no clues about what a chalet is
supposed to be (in french, a chalet is a type of construction found in the
mountain made of wood and does not imply anything about it's possible usage)
Could you be more specific about the differences between a
{{tag|tourism|chalet}}, an {{tag|tourism|hostel}} or a
{{tag|tourism|guest_house}} ? In a "chalet" is the owner sleeping in a
different building ? Does breakfast can be brought by owner ? Is a "chalet"
rented by the same group, by different group ? Can you rent one place only ?
one room only ? Who does the clean up of rooms ? Are bathrooms dedicated
"per groups" ? Is there a possibility of restaurant service ? is that
optionnal ?
Thanks for your answer to help me found what is the french equivalent of a
"chalet"

 It is amazing to see how few people participate in this discussion and

 compared to the number of mappers.

I will only talk for myself : I'm very interested in the outcome of this
specific discussion about tag proposals, and I did my best to make my way
thru the 6 threads on 2 mailing lists + a wiki page for a total of around
100 messages. 
But that is far too much time consuming not only to read, but to answer
while it was probably allready answered in another branch of mail thread
number 5.

A mailing list is not suited for that purpose for the time I'm ready to
invest. I'd welcome a summary somewhere (a wiki page ?) after a first pass
of discussion about the, says, 5 proposed changes of the proposal process
that have met a few supporters.
proposal 1- Voting quorum upgrade to 15 voters
proposal 2- 2 thirds approval required to have the accepted sticker
proposal 3- Voting period extended to 2 month
proposal 4- Remove all words that make people think the wiki process is
somehow an official and only way to accept tags
proposal 5- give free ponies to mailing list contributors who passed the 100
emails mark in the month
proposal 6- disregard any previous proposal and let every one do what they
want

ps: do we have a process for changing processes ?

For information, that proposition was created a few month after the

very_bad/bad/good :

But wasn't accepted as it didn't change the core subjectivity of the

remember that 3 is lower than 4) than remembering intermediate is better
than good

no, because the smoothness tag isn't about smoothness of the surface

If you intend to replace all type=deciduous to leaf_cycle=deciduous send a new 
email with a new title so that people know what you'r up to.
But I'still against integrating that change to a well understood mechanical

 To be clear:
 Initial post to the mailing list involved:  *removing useless fixmes*
 Based on list feedback, the discussion shifted and was focused on one task:
 * remove denotation=cluster along with the fixme* (the fixme was in fact
 recognized as flag for the bad data).

I'm still okay with that. As long as it means removing denotation=cluster as 
it was automatically added with the  fixme=set␣better␣denotation. But not 
manually entered denotation=cluster like :
http://www.openstreetmap.org/node/2919343692/history
If you wish to, please send another email with title : removing all 
denotation=cluster tags on natural=tree

 On the table now: * performing remaining needed cleanup on objects that
 will be edited anyway*

And I'm not okay with that unless discussed on a separated topic

 Hi,

Hi,

 OSM-talk-fr sounds like associating agglomération and speed limit.

I don't think we do. 
A french agglomération implies some speed limits (bellow 50km/h)
But speed limits doesn't imply you are in an agglomération.

An agglomération is more than that, and I don't think there currently is an 
agreed way to tag them...
 
 However, at least in Belgium, the definition of agglomération is very 
 strict 
Same here :
http://fr.wikipedia.org/wiki/Agglom%C3%A9ration#France

 How is an agglomération tagged?

I would suggest something in the place=something format + name=x
And if the wiki doesn't give any clues, it might be that we just need someone 
writing a proposal and start discussing that matter.

 Is my reasoning correct that I should I make a relation containing the 
 roads?

Do you mean roads as member of a relation ? I wouldn't advise to do that, but 
maybe draw an area around the agglomeration, or, before that, start 
discussing it on the wiki.
 
 But how do I tag it so that software recognize it as an agglomération as 
 described above???

When a new tag is created, chances are that no software will reconize it right 
away, but by explaining somewhere how you tagged it in a clear (and 
unambigous) way then everyone doing a software will know how to recognize it.

 Well, if I too consider just the speed limit, I see that Speed_limits 
 http://wiki.openstreetmap.org/wiki/Speed_limits applies to roads, 
 railways! and waterways!!!  Not relations !

That's the current state of recommendation, but maybe we could start 
discussing it to see if that's a good idea to apply speed limits on roads 
inside a bounding polygon

Hi,

Le mercredi 21 novembre 2012 22:53:53, A.Pirard.Papou a écrit :
 Look at multilinestring, which I see as a swiss-knife way assembly.
 
 In my mind, such a relation is the way to assign the same tags to a
 collection of objects making a whole with regard to those tags.  If we
 add recursion (nesting), which is very easy to do, that's powerful.

You misunderstood the idea/goal behind the multilinestring proposal. It wasn't 
created to factorize tags of all members. It was used to record one real life 
feature made of 2 or more OSM way objects. (like a long river, a boundary 
between two countries all made of hundreds of ways) 

A key sentence has been added to avoid using it badly : 

Do not use it to group loose ways : Relations/Relations_are_not_Categories  
(like all path in a forest) Example : if the name is not the same for all 
those ways, then you'd better not use this relation

What you are looking for is a category thing to group loose ways sharing a 
common property but relation weren't made for that :

[Tagging] What is and what isn't a valid type=multipolygon relation for osm ?

2012-10-13 Thread sly (sylvain letuffe)
Hi,

In response to this change on the wiki :
http://wiki.openstreetmap.org/w/index.php?title=Relation%3Amultipolygonaction=historysubmitdiff=820392oldid=797879
(which I do not completely agree with to say the least)

I think it should be discussed and agreed on. Perhaps with more examples of 
what is valid and what isn't.

Reading this :
http://wiki.openstreetmap.org/wiki/Talk:Relation:multipolygon#Multipolygon_should_consist_of_polygons_rather_than_ways

we can guess that it is hot topic, but allowing the wiki to change what is 
accepted or not every now and then isn't really something usefull I guess.

What about splitting in two maybe :
- what is considered valid/accepted from an OSM point of view

- what is considered good practice/avoid if possible from a mapper/consumers 
point of view

 Strange you mention that.  (...)  Then I noticed that 
 municipality names I wrote were being changed without discussing them 
 and without warning. It turned out that those changes were made by a 
 Frenchman who was also forcing that character upon us (1). 

It wasn't that strange that I mentionned that (it was a test to see if I was 
the only one disagreeing with him)
Yes, I know him too well, and we had an argument on that point (and on many 
others, but I won't publicly extend on it or I'll probably end using not nice 
words) on which he replied that I was the only one arguing against and that 
every one was happy with a — instead of more common characters like / - or 
whatever.
I now know he was/is a liar. 
That particular issue is so small that I won't start a war to change — in 
whatever, but you have all my support if you wish to do so.
Someone has to tell him that he cannot just change that on a global scale 
without consensus.
(Since I also don't care about names on boundary, I won't change things, but 
he is kind of pissing me off... once more)

 When I suggested the route recursion solution (a too restrictive

Such a solution was allready used for France boundaries, and explained on the

And a live example was set up (France).

Re: [Tagging] Naming boundary ways

2012-10-04 Thread sly (sylvain letuffe)
 I had assumed it was constructed differently but maybe it isn't.
ok

It might, but if it does, it shouldn't as it would be an error as far as what 
we have documented for it is concerned.
But since one french contributor has decided against all others's will and 
local practices to change as he see fit several times, your comment raised in 
my mind the idea that he might have tried it again.

 There's  
 a relation in Chile where the admin=4 relation consists of all the 
 admin=6 relations or so, this is what I meant with different concept. 

Spain as well is using those subarea role constructions (in addition to the 
other model)
We spent countless hours in France evaluating the pros and cons of both 
methods but ultimetly coundn't decide wich was better so we sticked to what 
we called the boundary model (in opposition to the surfaces sum model)

But that is off topic.

[Tagging] dispute about how to tag a type=multipolygon relation

2012-06-07 Thread sly (sylvain letuffe)
Hi,

A recent proposal (and change after that) on the wiki has been made, which 
roughly sums up to : relations type=multipolygon's members should only be 
closed ways, not sums of ways making closed rings, unless the way is too big 
that it would be refused by the API

Full discussion is here :
http://wiki.openstreetmap.org/wiki/Talk:Relation:multipolygon#.27outer.27_and_.27inner.27_should_be_.22closed_lines.22_.28areas.29

I think that's an important change to one of the mostly used relation type 
(multipolygon) which should be a little more discussed before validation.

Your opinons are welcome.

Is it a necessary simplification to those relation ?
Is it for the sake of some badly made software ?
Does supperposing ways to avoid factorising any type of area boundaries is 
much better, and if yes, for who ?

Re: [Tagging] dispute about how to tag a type=multipolygon relation

2012-06-07 Thread sly (sylvain letuffe)
 Let me first point out that these edits don't affect the definition of
 the multipolygon relation per se. 
 No relation would become invalid, so 
 this doesn't break anything. 
To be honnest, by what I read of the change, it wasn't so obvious.
When reading :
Use multipolygons only if there is no other way to map something
Don't split highways into shorter segments, to create an outer-ring for a 
multipolygon

Does seams order like to me, maybe some sentences like :
Sometimes it is better to avoid spliting short segments for ease of editing
or
Both spliting or superposing ways is supported to build 2 touching areas 
represented by multipolygons, and you can choose the one you want that fits 
you better
whould have had my preference ;-)

 It is about which of the alternative 
 mapping styles is preferable when either would work from a technical
 point of view.

I understand that, and I think there is no one answer to all because it 
depends on the editor used, on the real case, on the tags we want to add to 
ways (if any)

 My opinion here is that multipolygon relations should not be used
 unnecessarily. So if a closed way is possible (no holes, small area),
 then it should be used instead of a multipolygon.

I share that opinion on small area as well, although my small isn't 
probably your small, but whatever, I think people should be let to decide 
with both solutions explained on the wiki at equal, not expressing it some 
ways one could think it means can't or don't

I do personnaly use multipolygons every now and then, but not for isolated 
areas, because I don't need them in that case, but whenever there is a common 
border of say... more than ~30 nodes between two areas (a forest and a lake, 
forest clearing, lake and beach) I find if more convenient to re-use the 
border in a multipolygon that re-drawing two ways on top of each other.
 
Still, I use both method, even the extra simple one without multipolygon at 
all, which is my prefered for small and isolated areas

Hi,

I'd like your opinions on the following proposal :

http://wiki.openstreetmap.org/wiki/Relation:multilinestring

You are wellcome to discuss it either by replying to this email or by 
commenting on the wiki.

I'm also willing that this proposal is used, as a first step, to replace 
http://wiki.openstreetmap.org/wiki/Relations/Proposed/boundary_segment
which I previously proposed without public audience.


As a independant side note :
I am willing to activate the wiki voting system for this proposal as it seams 
most relation proposals never used it and have a tendancy to evolve in a way 
making them incompatible with their previous definitions

 In the proposal it says:
  If you have one way making up the line string ring and it does not
 describe something in its own right, you may also put these tags on
 the relation and leave the relation untagged. - that does not really
 make sense to create such relation (one way tagged relation would make
 splitting the way easier).

Oups, looks like a copy paste error, there are no reasons to have rings for 
those relations and instead of relation read way for the 2nd relation, 
I'm changing it in the wiki.

 
 The order of the relation members does not matter (but properly
 sorted member lists can help human editors to verify completeness). -
 I believe it should be always sorted, yet routers/renderers should not
 rely on it.

Well, I'd say it's better if but since it will not always be the case, data 
consumers should not rely on it.
A API server side re-ordering whould be cool, but that's not part of the 
proposal

 How would it be used in this situation?: border of two countries (A,
 B) is also border of lower administrative divisions (AC, AD in country
 A and BE,BF in country B). going along the border you go through
 different combinations (A-B all the way; AC-BE-AD-BE-AD-BF; see
 image). In reality there would be more than two levels and therefore
 much more combinations.

Either you keep this model for the higher admin entity (country) like it is 
used now sometimes with type=boundary_segment, or, at your option, or your 
local community's, goes as deep as you want. That's also why this 
proposition, unlike the type=multipolygon one, expressly states that it can 
be used recurrently with other type=multilinestring as members

 How would it solve the case of river bifurcation if the river merges
 together (river island, the same river flows on both sides)?

It will not.
However, it can be used for the main line river, wich, in turn, could be 
member of a type=river relation.
I designed type=multilinestring as a geometry model, not as a fancy 
ever-changing relation with roles or nodes. It can be used as being the 
member of other complex relation grouping several features, but building it's 
geometry is meant to be as stable in time as possible.

 How would it solve similar case of streets (lanes for different
 directions split for some time and later merge together)?

Same, it will not.

Re: [Tagging] Proposed feature : World wide place=* standardisation only based on population

2010-06-01 Thread sly (sylvain letuffe)
(Multiple answers)

First, I'm aware that full classification of every populated places is not 
possible world wide with one tag only, the proposition states that clearly.
administrative, interest, tourism, local concerns need to be recorded with 
other tags. The problem I see with actual place usage is that it is not 
standardazided world wide and serves merly for writing a label on a map.

It makes it quite hard for newcomers to guess in wich case they should use 
wich place, and that proposal tries to help have a first easy step to record 
at least a population estimation.

 tenths of cities and smaller countries - say, dunno, Uganda - get
 none.
Well, this is the truth ;-) based on such a scale. I don't see any problem in 
uganda having no megacity, because it's what is.

 I like your motivation. But maybe it's not necessary. Using
 population=* achieves the same goal.

Yes it does, and it does much more precisely, this is the utimate solution. 
Unfortunetly, having access to this information is much harder when you are 
driving your car thru, than a rough estimate that gives you the approximate 
size of a hamlet (I have to admit that the upper part of the scale is kind 
of useless as population data is much easier to get in those cases)

 +1 I doubt you could ever standardise cities, especially not based on
 population alone.

That proposition is not about standarisation of cities around the world, it's 
about standardisation of the place tag usage in the osm database. I don't see 
any problem if a place=city is actually a town in the local language usage, 
(let's add a common_denomination=town) just like in france we dont care that 
our villes are tagged place=town. I'm concerned about database storage and 
meaning of the data, and key values could just have been numbers, but it's 
harder to remember.

 consequence, while it is good to see the map of France showing five
 cities, Italy's map should instead contain a few tenths. Of course,
 this cannot be achieved if we only look at population - especially if
 we want to use a world-wide population criterion.
 
 I hope the idea is clear.
Unfortunetly, I think I get it, you have invented/searched perfect Italian 
thresholds in order to make the map...@osm.org map look what you are used to 
see. Maybe you endeded to 47000 people max for a city In order that city X of 
46999 isn't shown, because it's administrative role is not enough to apear at 
zoom 10 ?
Wich, in other words is a way to say you addapted the tagging of places to the 
actual mapnik style sheet at osm.org. Is osmarender rendering the way you 
want ? maybe no... Will it survive the next map...@osm.org stylesheet 
update ? maybe no... 
I don't blame that need, of course, map...@osm.org is the perfect portal of 
the projet, and it needs to bring a decent map that every country is happy 
with, but that's tagging for the/a renderer.

What I'm looking for is go thru a first step where maps won't be as perfect 
has we want them to look (population based representation of population) 
before we consider the need of other tags in order to render correctly.

[Tagging] Proposed feature : World wide place=* standardisation only based on population

Here is another try for world wide standardisation of places in order to 
hopefully try to create a consistent database and not a renderer work around 
font label positionning system

  +1, I agree. Inside a landuse=residential we could than map the
  different surfaces. I'd suggest to use the key surface for the
  ground-cover, or is there a problem with it?
 
 
 Having a ground-cover tag would be perfect.

What about 
every thing but boundary is ground-cover surface ?
(I haven't checked the whole map features)

 no, this is not the case. Multipolygon says: the inner part is NOT

I didn't say that ;-) I said : 
an area representing something inside another area would still be part of a 
multipolygon relation (I assumed people discussing this with me are familiar 
with the (advanced) multipolygon proposal and have assumed I was talking 
about an inner role in this case.)

 let the mappers decide.

So we do agree. My point was to stop or not to stop harrassing mappers that do 
not include inner polygons.
and/or not updating the wiki acordingly, giving the choice, mentionning that 
solution. We could let decide, but give clues about what's for what.

 For the lake in the forest: do you agree that someone would say: the
 lake (pond) is in the forest? Like a way in the forest, which doesn't
 have trees growing on it, but still is in the forest. It is not
 excluded.

That's a human language matter. I don't think it's good to stick a data model 
to verbs and words.

Between them, there should be interpretation, understanding, and questions 
answering. That is to say, programs. 

The data model should be able to answer maximum human questions (with 
programs)

Case of the lake in the forest, you could imagine multi-question to answer :
- what surface is this forest ?
Suppose I'm a wood lumber producer, I've got statitics about mean trees per 
square km. I'll surely want to exclude the lake's surface, as well as any 
road's surface going thru.
- is the lake in a forest ?
I suppose here I want to know if I can reach the lake by transporting my boat 
through grass fields.
