-1, what is the point of this? The key: capital already tells you, if it's a capital or not, and whoever makes a map can decide based on this information how to display them. If every capital became a Metropolis, the new key would be much less valuable. Cities in Europe that might be candidates for metropoles: London (several reasons, capital of the empire ;-), finance, infrastructure, art, culture, ...) Paris (several reasons, capital of the french empire ;-), art, culture, ...) (Marseille, infrastructure) Barcelona, Madrid Berlin, (Frankfurt, Hamburg, Munich, Cologne?) (Lisboa) Napoli, Roma, Milano, (Venezia) Vienna (UN) Bruxelles (EU) Warszawa (Budapest) (Praha) Москва́ (Минск) Istanbul Zürich, (Genève) and some others ... This list would have to be discussed and amended/shortened (sorry to everyone I forgot), some cities play an important role on a global level (like London), others are only of regional importance but can't compete in a Tokyo, New York, Los Angeles, Hong Kong, Rio de Janeiro-League. We would have to decide if our classification is meant to be relative to the region (read: continent / e.g. Europe) or at a global level. I agree with you though, that there might be cities worth a tag even not beeing in the multimillion-inhabitants region, so this should not be judged merely by the population but other factors would be important as well (infrastructure (port/airport), culture, economy, seat of international organizations) Population does play an important role though. It is not easy to compare the numbers, as they sometimes refer to the city limits and in other cases to the whole region around. When looking at the city limits one should be aware that those are not "naturally given", i.e. they are man made and can change / can be used to make the numbers seem bigger or smaller (besides other factors, like in less developed countries the numbers might be mere estimates). I suggest to refer generally to the metropol region and not to the city boundary when doing this comparison. Fortunately there is an incredible amount of research and publications on this ;-) some selected publications / sites: http://esa.un.org/unup/index.asp?panel=2 http://demographia.com/db-worldua.pdf http://www.unhabitat.org/ cheers, Martin _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
