[Tagging] Tagging parade_ground?

2016-03-26 Thread Warin

Hi,

I have come across a parade ground for Police - thus not military ...
There are a few instances of military=parade_ground ... but this is not 
military..


Would landuse=parade_ground be suitable.. or is there any other idea?

can you describe a bit more what this looks like, and how it is exactly used? 
Is this a piece of city where parades will occasionally take place (but which 
otherwise is just an accessible open space), an area where they exercise their 
parades, an area where people go to see a parade, or ...

[Tagging] setting proposals to abandoned

2016-03-26 Thread Martin Koppenhoefer
I wonder what others think about changing the status of proposals in draft mode 
to abandoned in the wiki. Is this something we want everyone to do after a 
certain time, or should this be reserved to the original proponent?
Would the situation be different if the status wasn't draft but proposed?
If you think everybody should be able to abandon other people's proposals, what 
would be a reasonable timespan?
Does it depend on the actual usage of the proposed tags, and if yes, what would 
be a reasonable threshold?

FWIW, the actual reason for this mail now is this edit, but I'm more interested 
to learn about your general considerations:

Some time ago I set some obviously abandoned proposals to abandoned, I
see no reason for "reserved to the original proponent"

"what would be a reasonable threshold" - no edits in this or previous
year is my typical method to recognise something on internet as dead.

but wouldn't it be necessary to look at actual map edits rather than on a wiki 
page (i.e. has the tag been applied to objects in the last year)? If the 
definition is settled there is maybe no need to make changes to the wiki, you 
can just use the tag.

I vehemently oppose introducing this tag for the reasons given by
Tekim, Gdt and Stevea at the Talk page of your proposal.
https://wiki.openstreetmap.org/wiki/Talk:Proposed_features/Social_path

It replaces a very old, very often used value by another new one and
its only intend seems to hide features from renderers/data users who
have not added support for your tag.

OSM maps what's on the ground. If there is a path, it is mapped as
path. If there is a sign/information board which prohibites using
unmarked trails, people add access=no to "unofficial" pathes.

There is already a discussion about this tag at German forum.
Proposals usually get discussed there when voting starts. Usually
people who hang out there only get notified if the proposal is bad.
Your proposal has been mentioned there today.

First, big thanks for bringing this to the list.

I do think, however, you are mistaken with the above rationale, which
appears to be the sole rationale for the proposal.

access=no is absolutely a core tag within OSM, dating back to the very first
iteration of Map Features. It isn't "easily ignored". Any router which
ignores it is unambiguously bugged. Any renderer intended for walkers'
consumption which shows it as a walkable path is unambiguously bugged.

It is not, however, documented or safe to assume that renderers and routers
will always fall back to "no". There have been renderers which will render
the name for an unknown highway value, so 'highway=social_path;
name=Shortcut' would show on the map as a label saying 'Shortcut'. There are
routers which will assume a default speed for unknown highway values. That
isn't always daft: you can envisage a single typo in one two-node way
('highway=mptorway, maxspeed=70mph, surface=paved, access=yes...') which
would otherwise break routing across a continent if the router was entirely
fault-intolerant.


To widen the discussion, introducing new core path values is bad OSM
citizenship.

Path tagging in OSM is notoriously complex, for one reason: people keep
reworking the core model to deal with their edge-cases.

We began with highway=footway/bridleway/cycleway/track, surface=*, and
access/foot/bicycle/horse/motor_vehicle=*. With these values, you can model
the essential characteristic of 95% of paths (conservative estimate).

Some people identified edge cases which they felt were not adequately
captured by this scheme, and therefore introduced a new, more complex
scheme, highway=path.

Later, others identified still further edge cases and introduced yet more
values: access/foot/bicycle/etc.=designated. Later later, others identified
still further edge cases, and we got access/foot/bicycle/etc.=official.

And so on. Every such change has made the system more impenetrable for
mappers and consumers, and we have, I believe, a collective responsibility
to keep OSM usable. I won't bore you with the details of the Lua tag parsers
I use for cycle.travel's path routing and rendering, but they are insanely
complex - hashes upon hashes upon hashes, special cases upon special cases -
and yet there are still bugs and edge cases. How anyone who doesn't have
years of experience in OSM is meant to cope with this, I don't know.

The best way to map these, without adding further burdens to mappers or
consumers, is to use broad-brush, well-established tags such as:

 highway=footway
 access=no

and then, if you feel this doesn't fully capture your particular edge case,
some sort of _additional_ tag:

 social_path=yes

(The classic example of this is motorroad=yes, which the German community
introduced as a refinement on highway=trunk/primary, and which has since
become a successful and widely-adopted tag without breaking highway routing
or rendering.)

But please don't extend existing core tagging, such as highway=, in new and
exciting ways. It doesn't necessarily solve the problem in the way you think
it will, and it makes it harder for everyone to use OSM.

cheers
Richard

Yes but one thing is the proposal, the other is the actual usage of tags.

While the actual map usage should be documented on the tag page,
still the proposal can be considered abandoned.

The typical thing about Abandoning is that the proposer has "ceased to
support or look after" [Oxford], the active role of the proposer would be 
Cancelling.

There is a wiki page about the proposal process, which recommends abandoning
after 3 month, which I think is too tight.

In the specific case, the proposal was to fully replace 'kindergarten' with 
'childcare',
which was proposed 28 months ago, and has also not happened in practical 
tagging.

This is quite in contrast to successful changing schemes, such as nursing_home
to social_facility + sub-tagging.

The unfortunate issue with 'childcare' was the insufficient differentiation from
other tags in the first proposal, and the unnecessary attempt to replace an 
established
tag in the second. The tag page is extremely vague, so at the end of the day
nobody knows what an object such tagged is in reality.

The status should in some way make it clear to people who use the wiki
as a tagging reference whether the contents of the page should be taken
into account or not. If the proposal has been "abandoned" but what is
suggests has nonetheless entered wider usage, then it is de facto
accepted by the community, and you could not easily make a case to say
it should not be followed. If the main wiki has not (yet) been updated
following the proposal, then labelling the proposal as "accepted de
facto" would be a simple way of confirming that it is still relevant.

This is fine when there is one clear proposal and people just started following 
it.

In the specific case cited, it is unclear which of the two proposals the users 
of the tag follow.
The tag page is there however, and the users can document what they do.

[Tagging] service = parking_access for main ways on a parking lot

2016-03-26 Thread Tom Pfeifer

The qualifier service=parking_aisle was originally introduced [1] to
structure car parks with a few main access ways and lots of small aisles,
to avoid clutter in lower zoom levels.

It is highly successful with over 2 Mio uses.

The description says that, however "The main way(s) on the parking lot,
for entering and connecting multiple parking_aisle, should be mapped with
highway=service, only."

Apparently, mappers feel a void in tagging highway=service only, without
a qualifier, and add parking_aisle to all ways related to parking, thus
losing the structure.

Thus I would like to use a different qualifier for those ways entering
the lot and connecting the aisles, e.g. service=parking_access.

This does not break any consumer, is not used so far (ok, once, exactly for
the purpose), and also solves a recent question in the wiki for a related
problem, a separate parking road parallel to a main road.

Opinions?

I agree with the intention to have 2 different classes of service.
sometimes, not too rarely, those ways are not only for access to the parking 
but also to pass through, to go to the main entrance (e.g. for the boss, for 
honorable guests, for disabled, etc.) or to go to another site. Would we have 
different tags for all those possibilities? I think I prefer service without 
additional qualifier for the second class, but if you come up with something 
more neutral that still bears the hierarchy connotation, I could support it.

Interesting perspective. So we have currently
('parking_aisle', 'drive-through', 'driveway')
which are treated as the minor class in Carto.
'alley' is another minor value not considered there.

So what would be a good value to be wider than just parking?

- access is more general than parking_access, but
  not very self-explanatory. Used 500 times,
  predominantly with highway=service

- main implies some importance, is used 450 times in
  the railway context.

I had no idea that it said that.

What I do is

  * highway=service service=parking_aisle
ways that are basically only to get to parking spaces

  * highway=service service=driveway
ways connecting to the real roads and sort of going near where you
are trying to go when you want to park in the parking lot (carpark),
just enough to be connected, and trying to pick  the places that are
more important/through roads

The latter is more or less what your service=parking_access is trying to
do.   But if for example you want to pick someone up at the front door
of a supermarket, and not park, you'd use them.   So parking_access
really isn't quite right for most of these ways.

I too have been using service=driveway for the non-parking highway=service 
roads found in parking areas. It wasn’t until this discussion came up that I 
realized the wiki said there should be no service=* tag for those.

It seems to me that any highway=service ought to have a service=* tag. Whether 
the specific case being discussed needs a new service=parking_access tag or if 
service=driveway is okay would be the discussion I’m interested in. To Tom’s 
point, I think a roads for many commercial areas would have a big grey area in 
deciding between driveway and parking_access as often the route to the main 
entrance and/or loading docks is indistinguishable from the other roads in the 
area that simply service parking.
