I, on the other hand, find it easier and also more logical to map the
whole area that has the same surface.

Re: [Tagging] Tag which restaurant or cafe allows bringing your own food or drink?

2023-05-23 Thread Frederik Ramm

Hi,

in my opinion such tagging would only make sense if these rules were 
signposted at the restaurant.


In the restaurants that I frequent, what you describe would basically 
mean a prior phone call - hey, we're booking a table for dinner for 6, 
but one person has to bring their own food, is that ok - and they would 
then say yes or no and it would totally depend on how busy they are, 
whether you are a frequent customer, whom you're speaking to and whether 
they like your voice. Extrapolating from such an instance to some form 
of general claim that things are always like this at this restaurant 
would certainly be wrong.


And I've never seen a restaurant where they signposted that their policy 
was that you can bring your own food. Except of course old-style 
Biergartens in Bavaria.


Bye
Frederik

for the avoidance of doubt you could add barbecue_grill=no as you’ll have to 
bring your own if I understood it well, or could you just light a fire on the 
metal plate?
https://taginfo.openstreetmap.org/keys/barbecue_grill#overview

The barbecue tag is not really used a lot and some values indicate a type of 
barbecue grill https://taginfo.openstreetmap.org/keys/barbecue#overview

There is more use for “bbq” but it is defined as “a bbq grill is available” 
(property) https://taginfo.openstreetmap.org/keys/bbq#overview

I’d use a more specific tag for this feature, or maybe a generic property like 
fireproof=yes/partial on the table ___

Hi everyone,

So if I understand correct most parking spaces are mapped as polygons?


yes
https://taginfo.openstreetmap.org/tags/amenity=parking_space

I don't see the problem to add a width and length tag to a 
parking_space node,


there is no problem except to be aware that this is the least common 
schema and the one that gives the least information, and that 
therefore any contributor can convert a width=A length=B into a 
surface object having this dimension and which will also give a 
position of this object in relation to the others (does the parking 
space touch the neighbouring parking_space, does it touch a kerb, etc)


because this is more detailed info about the dimensions of a parking 
space,

that is actually measured by people on site with a measure tape.
the polygon data is not accurate enough to really use for our app.


I don't understand this argument despite the fact that to repeat it :
a node width=A length=B is not more precise than a polygon
with thoses dimensions



The polygon gives the orientation - could be parallel to the road or at 
some angle.


I prefer the polygon, more trouble to map but you can use imagery to get 
it.





Are there other apps that add info about parking places as polygons and
extract dimension info from the polygon data?


most map style, including osm-carto (the main style on osm.org)

Can anybody recommend a sub-tag that's more descriptive than barbecue=yes?



To me barbecue=yes would imply there is a bbq there not that I would 
have to bring my own?


See

And - more relevant - from the above page

"bring_own_bbq=yes – tag proposed[1] and considered as a good idea[2] 
for places where one is allowed to bring barbecue, but there is no grill 
or firepit provided on site.


    As of 2020, there are >10 instances of bbq=bring_your_own [3], 
compared to 1-digit of bring_own_bbq=yes [4]."

but what's the playing area ?


Yep, good question, with no across-the-board answer!

As you say, you can play tennis from "outside" the court, but in most 
ball games, if the ball (& sometimes player) crosses the marked line, 
that's out!
In cricket and soccer the ball and player can be 'outside' the marked 
line but in the air. Only when the player touches the ground are they 
'out'.


& then for cricket, the "cricket pitch" itself is a small rectangular 
strip in the middle of the field, but the game uses the entire area of 
the field, while the boundaries of the field are an essential feature 
of the game.



Err cricket uses less area than Australian Rules Football and sometimes 
the two cohabit a facility.


So the cricket 'field' will be smaller than that football field.

Where cricket and soccer occur together there are sometimes 2 soccer 
fields with the cricket pitch in between the two soccer fields. The 
cricket field does no take on the outer boundaries of the 2 soccer fields..



Does the 'playing area' of chess include the table and seats?

Then think of water and snow skiing...
