Independent from this particular problem manually tagging importance ratings is a really bad idea. Importance of a feature is nearly always a multi-criterion quantity. To make such a rating verifiable would require to have a recipe to calculate it from other observable facts - and then it is better to tag these facts rather than the combined rating calculated from them. As i have said on github the runway length would be a fairly good criterion for importance and it is very widely available already (35551 nodes aeroway=aerodrome with 31752 ways aeroway=runway). The problem here is not having this information mapped i think but querying it from the rendering database. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
