Re: [Tagging] Mapping pergolas/arbors

I would discourage the use of type as a key here as it is used to differentiate 
between relations. Suggest shelter:type or something similar. Cheers Dave

Yes Martin, you're correct.

Based on the discussion here, I will plan to go with amenity=shelter, followed 
by type=pergola.

it can perfectly be both, e.g. a tower is also a building

Fully agree, producing biogas is a function, not a building type.
Such digester would be similar in tagging to a man_made=wastewater_plant.

Further I think that man_made=bioreactor would be easier to understand
internationally than digester.

I think I know to what discussion you refer, and me, too, had some doubts about 
“digester” being a “building”.
But there are more such “mistakes”. To me a greenhouse is NOT a building. Of 
course, it is built, but every "man made" object is built, but that doesn’t 
mean it is to be considered a building.

And as a side note I could say:
Combining man_made=* AND building=* on the same object (as is often done to 
make it appear on the map) is as wrong as using highway=* and waterway=* on the 
same object. It is one or the other, but cannot be both.

I spluttered a bit when I read on #talk-gb that and RichardF has since
corrected it to say that rule only applies in German speaking
countries.

this might be country specific, AFAIK according to the German law, a
station without a switch is not considered a station but a halt (not sure
if we should add this requirement to OSM though, cannot recall that we
discussed this on an international level, so that adding it into the
general wiki definition doesn't seem right).
I agree that even for small facilities a node is rather the preliminary
than the ideal version of mapping. Everything with a spatial extent of
railway infrastructure is likely better mapped as polygon (to allow for
things like A is inside B or A is bigger than C, etc.)

Martin

Re: [Tagging] railway stations as areas / nodes

There does appear to be a fair bit wrong with that page, it says 'Stations 
without switches (should be points) where only passenger trains stop are called 
halts.

A halt should be a station where trains stop on request. The wiki would make 
most stations into halts, including busy stations, such as Telford, which is 
ridiculous.

[Tagging] railway stations as areas / nodes

[Martin Koppenhoefer]

One year ago, as I just noticed, the wiki page for railway=station was changed 
significantly, removing the suggestion to use areas and insisting on using only 
nodes for railway stations:

https://wiki.openstreetmap.org/w/index.php?title=Tag%3Arailway%3Dstation=revision=1140728=1115036

I don't recall any discussion here about this topic, but I believe that this 
edit was not reflecting well the actual situation (at least not around here), 
and should be reverted.

What do you think?

Cheers 
Martin

it could also make sense to add building=pergola to the historic structure you 
linked before. If you decide to add a type tag, use shelter_type. Pergola is 
currently not among the values in use, but similar words are: 
http://taginfo.osm.org/keys/shelter_type#values

As for shelter to protect from the sun but not from rain: the amenity=shelter 
tag doesn't seem to be intended for these cases, as long as you don't consider 
sun shine "bad weather conditions": 
http://wiki.openstreetmap.org/wiki/Tag:amenity%3Dshelter

"The amenity=shelter tag marks all sorts of small shelters to protect people 
against bad weather conditions."
