So there you have a city (admin level = 8) that crosses county (admin level = 6) and state (admin level = 4) boundaries. That's odd, but in my opinion is mostly all right, since these things do happen. New York has: 1 Native American reservation (admin level controversial) that, its citizens insist, lies on both sides of the Canadian border. In practice, its citizens do not need to clear passport control to pass the international border within the reservation; non-citizens of the Haudenosaunee nation do. 1 city that is coterminous with five counties (we created a special admin level 5 for New York City, which is sui generis) 1 city that has annexed land in an adjacent county Several counties and towns with indefinite boundaries 1 hamlet that the state won from Massachusetts in a prizefight. (Petitioned 1848, ceded 1853, confirmed by the Congress 1855 and annexed to the Town of Ancram 1857) About 15% of the villages (admin level ? - perhaps SHOULD be 10, but in any case should be below Town/City) cross town lines (in which case the residents owe taxes to the village and to whatever town they happen to live in). Administrative levels do not form a hierarchy. That's simply a fact that we have to deal with. These anomalies are quite common in the US. I sometimes get the impression that mappers in other countries shake their heads and say, "the data model is fine. Fix your country!" Nevertheless, the boundaries are where they are, and we have to do a "least worst" approximation to represent them. Oddly enough, what I proposed for New York does not create any cases of overlap at the same admin level: 4: New York does not overlap the territory of any other State (except for a largely dormant boundary dispute involving a few islands in New York Harbor). 5: Special case: New York City comprises five boroughs (which are counties whose executive and legislative authority has been largely ceded to the city but maintain an independent judiciary). No other entity at level 5. 6: All counties are disjoint. Every point in New York is in exactly one county. 7: All towns/cities/Native American reservations are distinct. Every point in New York is in exactly one of these. Their boundaries usually follow county lines, but the cities of New York and Geneva are exceptions. 8: All villages/hamlets/community districts are disjoint. Every point in New York is in at most one of these; however, many people do not live in a village, hamlet or community district. (For instance, I live in the Town of Niskayuna, which has no signed hamlets or incorporated villages.) The boundaries here are quite arbitrary, and about 15% of villages cross town lines. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
