Yes, the discussions and proposals are endless for this. Suggestions are usually that you should deduct the importance by analyzing the map dat (e.g. surface of the runway, length of the runway) and combine OSM data with external sources (numbers of starts/landings a year, number of passengers a year, freight volumes, ...). Personally I think that to get a rough estimate it is sufficient to tag the most important ones with aeroway=airport this renders nicely and is suitable IMHO, even if it is not the ultimate level of detail. cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Seems pretty simple to me, importance is going to be partially subjective, even if 2 airports have similar number of flights, some will have 747s & 380s and some won't. highway=* classifications seems at least partially subjective as well. I see the need for at least 4 or 5 airport types, major international airports, minor international airports, regional airports, tiny airports and airstrips. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

I'm a fan of subtagging :) So I'd be more likely to do something like this: aeroway=aerodrome aerodrome=[major|minor|regional|airstrip] ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Looks like this tag is already in limited use. There are 30 objects with aerodrome=international and 15 with "private" so those could probably be easily converted to major and airstrip, respectively plus perhaps an access=private.
