All that runway 'way' XML contains is one tag that says it's a runway. The problem is there is no easy way to correlate a runway to its airport.
The wiki convention does not create any problem for visual map style applications, because they have spatial awareness. The problem is for non-visual applications, especially the one am working on. I created an OSM file/table that contains only runways in the world. Another OSM file contains only airports. Am looking for an easy locate the airport for a given runway. For eg. Entering 30L in a search window should bring up "SJC" as the result. Note there can be multiple runways named 30L. Hope that clarifies the issue.

In the example you gave, it looked like two clearly marked runways. I don't see any problems with them. The "aeroway=aerodrome" tag can be used on either a node or an area. Most of the time it is a node placed near the center of the airport. When it is used on an area, it marks the grounds or boundary of the airport. For example: http://www.openstreetmap.org/browse/way/5024354 I don't think it is a good idea to put the iata or icao codes on the runway, because they really apply to the whole place. They should go on the aeroway=aerodrome item (node or area) like the wiki says. - Alan _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
