Hedge requires area=yes when used on an area. 

I use it for median and sidewalk hedges all the time.

 leisure=track, (With area=no because leisure is a key which suggests an area

No problem with platform as way (line) but as closed way, really.
Wonder about platform building a "ring" but no area. All the the ones I
know at least have different ref=* and therefore need to be splitted.

Could you show us a real world example, please ?

Same problem as highway=*, you never know if a closed way tagged with
aeroway=taxiway is an area or a loop.

As far as I can judge a clean separation would be the best:

for highway and aeroway representing the area as area:highway=*
respectively area:aeroway=* and only tag ways with highway and aeroway.

Hi

I thought it was required for platform as some were being drawn as a 
single line & as OSM has no specific closed polygon entity, renderers 
can't tell if it's an area to be filled or an extremely squiggly platform.


Ah, I forgot about aeroways. I'm surprised the conclusion was the width 
tag. With locations that have aerial imagery it's much more accurate to 
trace its width. Couldn't the renderers adapt to both? If it has area 
then fill it, if it has width render it as such.

 From memory the only two I know that can require it are railway=platform
& highway=pedestrian when drawn as closed ways. Are there any others &
do other renderings have different rules regarding this?

railway=platform should not need it but renderer are sometimes dumb.

highway=service are often drawn as area and I have also seen
highway=path/footway

Another subject are aeroways=* though the last discussion ended in
preferring lines and have the renderer interpret width=*

There are some barriers like wall and retaining_wall (city_wall ? )
where an explicit area=yes makes sense.

In the end we could always use a multipolygon for areas where it might
make problems to distinguish between closed way but line and closed way
and area and could get rid of area=yes.

[Tagging] Which entities use area=yes

2015-04-07 Thread Dave F.

Hi

As I was tidying up some data in my locale I noticed area=yes sub tag on 
natural=wood which, AFAIK isn't required.


From memory the only two I know that can require it are 
railway=platform & highway=pedestrian when drawn as closed ways. Are 
there any others & do other renderings have different rules regarding this?
