only for nodes?

Is there any reason why this tag should be used just for nodes instead the complete airport area? --Etric Celine 01:17, 7 January 2008 (UTC)

In my opinion it should be allowed for areas too. Especially because airports are usually large. The text seems to contradict the ValueDescription-Template in this aspect. --MRQ 18:10, 12 July 2008 (UTC)

I think there are reasons as long as it's rendered from a high "zoom out level".

• In mapnik it's rendered as a symbol at zoom level 10.
• in tiles@home it's rendered as a symbol at zoom level 13 Logictheo 14:36, 6 April 2009 (UTC)

Boundary Ways

I would like to tag an airport with an area, however, there are a number of different ways defining the perimeter in this case - some barrier=fence, some building=hangar, and some are ways of an administrative boundary too. It's therefore not possible to use the existing ways to form a closed node to share the aeroway=aerodrome property. The solution seems to be using a multipolygon relation to gather the boundary sections using role "outer" then apply the aeroway tags to the relation. For buildings that form part of the solid boundary I have created an additional barrier=wall way for their outer edges, as closed ways can't be included as part of multipolygons. --Pink Duck 11:39, 26th March 2010 (UTC)

I have been spending some time looking at how people are modeling airports and haven't been comfortable with how boundaries are defined either. Personally I prefer to use 'aeroway=aerodrome' as a node so that I can position it where I wish it to appear, probably near to, or on the main terminal building. The boundary seems to be a separate entity, indeed I think there are multiple boundaries, including 'airside', 'main airport facilities', 'airport include all related parking, transport interchanges and services etc. Sometimes a boundary can be a simple way, but other times it will indeed be better as a multi-polygon as you suggest. I have also been looking at how one might use a 'site' relation to pull all the elements of an airport into a single container. Possibly the boundary could form part of that over-arching relation. Can I suggest that we discuss this further on the talk:Airports page? PeterIto 22:13, 14 December 2011 (UTC)
