For example http://en.wikipedia.org/wiki/Lake_Butler,_Orange_County,_Florida is a name apparently made up by the Census Bureau. In many other cases the names are real but the boundaries are bogus, often expanded to fill the space between incorporated communities.

Sometimes the actual incorporated community that has jurisdiction over a place is not accepted by the USPS. > McKinleyville, CA (http://en.wikipedia.org/wiki/McKinleyville,_California) is > as much a defined community as Arcata or Eureka to the south of it even if it > only exists on the map as a CDP. It's definitely a defined community, but are the boundaries really well-defined? What makes the south side of Baird Road part of it but the north side not? > Place nodes are worse than useless Perhaps you mean "useless for searching", since if something is worse than useless it should be deleted. > as demonstrated by the associations Nominatim generates from them.

That's partly Nominatim's fault and partly our fault (presumably the trailer park is tagged with a misleading place=* value). A better algorithm might be (if it's not inside a polygon) to give distances to nearby place nodes, rather than choosing the closest. > If you think the boundaries are wrong move them (or even better ask people on > the ground what the name of the place they live is, which is probably how the > census ended up with them in the first place). I have been replacing the CDP polygons in central Florida for a while with better-defined neighborhood polygons roughly based on platted subdivisions and zoning. The CDP boundaries were not useful for any of these, even as starting points. _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
