I recall reading that the US does indeed have a much higher density of airfields than most countries. That said, there's no doubt that the imports brought in some airfields that are no longer in use or don't exist. Sometimes this is obvious by just looking at aerial imagery or a quick survey from the air, but sometimes it's hard to say whether a field is being used as a private airstrip. AFAIK the FAA doesn't keep track of such private airstrips, or, at least, many are not on the charts or in publications like the FAA Airport/Facilities Directory. Anyway, I've been trying to clean up the airports a bit in my state, and I would very much like to see some form of classification like what you originally suggested. -- Lars Ahlzen l...@ahlzen.com _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
