The problem with this kind of tag is that while it can be in principle a verifiable tag - provided that the suggested values are clearly defined this way it is still an aggregate score designed for usefulness for certain data users rather than for good mappability. An example: In Germany civil airfields are classified by law into "Verkehrslandeplätze", "Sonderlandeplätze" and "Segelfluggelände". "Verkehrslandeplätze" is pretty much the same as aerodrome=general_aviation - i.e. can be used by pilots without prior permission by the operator. However "Sonderlandeplätze" is not the same as aerodrome=private - there are SLP that qualify as aerodrome=commercial because they have regular commercial flights. In short: Many of your suggested values are based on properties that are independent of each other. It would be more useful for the data user and easier to map for the mapper to document these separately. Specifically i see: * presence and nature of regular passenger flight service * openness to public from the air * access restrictions on the ground * presence of services for airplanes * surface and length of the runway And not in the proposal but a useful property: * restrictions to certain types of planes (like non-motorized gliders) -- Christoph Hormann http://www.imagico.de/ _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
