didn't you use a subtag for continuous/discontinuous? Could have been helpful. > But perhaps we could have something more accurate for city centers that > would be near Continuous urban. IMHO not all continuous urban fabrics are centres, or I don't get the meaning of this term according to my unsufficient English. > Why not a landuse=city_centre (according to the English spelling) if it fits > many situation throughout the world ? it is fitting for all historic European cities and might fit in other parts of the world as well. There is still some problem with it: there are mixed landuses in different parts of the city and some of them are very dense (usually the historic centre(s)), others are less dense (might be subcentres or too small/ not dense enough to form any kind of centre). And it is exclusive (not combinable with current landuses, but there might be specific landuses like purely residential or even industrial in the centre as well). If you like a taq like this, you could just as well use http://wiki.openstreetmap.org/wiki/Proposed_features/centre_zone which avoids "city" because centres occur in villages and other settlements as well. Still I think that an attribute to assign additionally to the landuse would be a better approach than using an exclusive landuse term for this. If we can find some consensus here how to tag centres I would change the proposal to fit. What do you think about centre_type (quoting from the proposal): centre_type=sub_centre - use this for local centres, that are not considered main centre of the whole city/town/village. Probably exists only in bigger cities. centre_type=main_centre - use this for the main centre, in big cities there could be several main centres, while in villages and smaller cities I wouldn't expect more than one main centre cheers, Martin _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
