Having a look at them & some possible issues?

https://www.openstreetmap.org/way/957372815 &
https://www.openstreetmap.org/way/919594591 may be duplicates of the same
spot, especially as there are markings on one & not the other?

https://www.openstreetmap.org/way/929622888 has included the runway
alignment ref in a note, as the ref is the Hwy number. I guess that should
be fixed by having a separate runway drawn over the top of the highway?

https://www.openstreetmap.org/way/975224506 may be a private strip, but
certainly doesn't look like a highway!

Thanks

Graeme

Should it be layer=1?



Err no.


There are some 9 aeroway=hightway_strip in Australia... they do not 
render on the standard map. Some 120 world wide.


The aeroway=runway does render hence there would be some who would use 
it in preference.



My thoughts are to map the area cleared for the aeroplane wing as an 
aerodrome .. this renders.

There are more than these 9. Searching for runways gives a great number 
.. many of them on outback stations.

Thanks Andrew. That tag is not on the aeroways page .. I have added it

https://wiki.openstreetmap.org/wiki/Aeroways

It was out of sequence on 
https://wiki.openstreetmap.org/wiki/Key:aeroway - now corrected. But I 
wounder how I missed it here?



I'll keep the area mapping (aeroway=aerodrome) so as to indicate the 
cleared area

Hi

How do we tag emergency highway airstrips, as used by the RFDS? I
thought this was documented on the Australian tagging guidelines
but I
cannot see it..

I have used this as an example

https://www.openstreetmap.org/way/493146070

for a rough area cleared for the wings and a turning area.

aeroway     aerodrome
military     airfield
name     Royal Flying Doctor Service Emergency Airstrip Stuart Highway
wikipedia     en:Highway strip#Australia


together with


https://www.openstreetmap.org/way/493146071

for the centre line of the runway itself. Note the highway exists
as a
separate way.

aeroway     runway
ref     13/31
source     survey
surface     asphalt


-

Anyone have thought on this? I'm not certain of

military     airfield .. may not always be military though this
area is
surrounded by it.

name     Royal Flying Doctor Service Emergency Airstrip Stuart
Highway
.. more of a description possibly operator???


Once this is discussed .. then I'll put it in the Aust. Tagging
Guidelines thingy.

use simple tools to filter the list for specific tags, most often
informal=* being missing.


Don't recurse down from your search results "(._;>;);", rather use out 
center; eg: https://overpass-turbo.eu/s/1C3T This will return a lat and 
lon that is the centre of the bounding box (which will mostly be OK 
except for the usual doughnut and snake cases).
