I was looking at "college" and "university", I thought "school" was just
another variations so I missed that...

it's listed on the Key:barrier page, but without any description. Though

The tag amenity=school is intended for the whole area of the school and 
its grounds. You can also map the school buildings, sports pitches etc 
within this.
This is clearly stated on this page: 
http://wiki.openstreetmap.org/wiki/Tag:amenity%3Dschool
So I'm not sure which examples or documentation you are referring to.

Maybe, I don't know if there's any better tag for that. You can also 
specify how high it is with the height=* tag.

[Tagging] More tagging questions

2010-05-07 Thread Jonas Minnberg
In Sweden we have special barriers in the ground that only larger vehicles
can pass, meant to allow buses but not normal cars - is there a tag for such
a thing or should I make one up?

Is there a a good way to define the area covered by school grounds? The
examples and documentation about education tags seems to only apply to nodes
or individual buildings - I would like something like landuse=school, which
would also be a good place to put the name of the school.

Should the cliff-tag be used even for smaller drops? I've seen it used in
residential areas where bare rock can be seen, but where the
height-difference is small enough to jump up on it without using your hands.

That's what access=private says (that it is a private property). If
you want to deal with the "around family house"-fact: draw the house.

well, then simply don't tag it like that.

Yeah, but as the thread says - we are talking about the green ones ;-)

You missed the point - I don't want to add the information about the
surface, I just want to say that this area is a backyard/garden around
family house.

Well, the first problem is that the surface may change during quite a
short period of time, so it doesn't really make much sense to try to map
it all and the idea of keeping that data up to date is crazy.
Second problem is that, personally when I look at the map, I would like
to know that "here" behind the fence is grass, maybe some plants or
trees, but I really don't care if it is a bed of carrot, roses, or
tomatos... or it's only plain grass.

I would like to see a difference in tagging the grassy area with small
basin (I wouldn't call this garden and neither would anyone who follows
description on OSM wiki) and "real" garden, both can be the same size.
Furthermore, it's not really true that you can with certainty
differentiate large gardens from a family house backyard, because it's
common practice to tag the whole block of these properties together with
leisure='garden', so that a lot of small "gardens" is joined into one
polygon.

I've probably mapped some as weighbridge already. Could someone use one of

Isn't the english language wonderful, you ask people from different

Hmm, to me there are three levels.

Crazy Clarks is bargain/discount
Target, KMart are downmarket
DJ's etc are upmarket

How should we tag a factory outlet type store that sell's upmarket
stuff at lower prices?  I can easily find stores that sell every
product at a very reduced price, but still don't sell anything less
than $100.  It's just that normally it would be $300+.

"don't map it" is a bad advice, lets say it's already mapped by e.g.
me as a leisure=park even though it isn't.  So the question is how do
you handle the edge cases, that someone as scrupleless as me would tag
as a park.

I would tag it as leisure=park, access=no

There are buildings which don't have atriums.  One could map it as
leisure=private_yard_between_houses  + surface=[green_stuff |
mostly_concrete] perhaps defaulting to render green  as a park.

Maybe it's hard to decide because there are so many words for semi
private yard, other words can be:
http://en.wikipedia.org/wiki/Atrium_%28architecture%29
http://en.wikipedia.org/wiki/Quadrangle_%28architecture%29
http://en.wikipedia.org/wiki/Courtyard
http://en.wikipedia.org/wiki/Patio_garden
http://en.wikipedia.org/wiki/Backyard

And that's not even counting what Petr wants, front side garden.
