Thanks Kevin.

That same geographic area/named place overlap/under-lap occurs worldwide.  I think that the Ordinance Survey has it right approach with the distinction between Spatial Thing(vocabulary) and Spatial Object(geography).  Eventually the geometry you want is that of a Cell Phone System (Tiled Hexagons, with a Point of Interest in the middle) as opposed to a Cartesian Coordinate "Wet Blanket".  You just have to make the Hexagons small enough to limit the radii of equi-error (isotherms, isobars, isotimbls maybe?).  The philosophical problem is that in a Cell Phone System signal overlap enables triangulation and tracking, the cells do not overlap.  Content negotiation between cell towers is automated.  So to put it another way, the tracking data channel is always open, but there is no mission critical systemic imperative to process the data in the channel. Angry Librarians, seem to have some company ... gotta go, if you need me I'll be on Earth.

-- No need.  Just curious if there was something we could do to help you more easily get to the data.

Should you continue to use ID.LOC.GOV data (and please do!), when it comes time to tackling national (and international?) divisions, I'll be interested to know how it turns out (and assist however I can). As I'm sure you've discovered, the Names scheme [1] at ID contains most geographic entries.  We do have a number of levels of (national and international) subdivisions, but unfortunately the source data does not necessarily record relationships (broader/narrower) between geographic areas.  For example, you can look up the individual components for "United States--Virginia--Spotsylvania County", but you won't find the relationships between those geographic areas expressed in the data.  

http://id.loc.gov/authorities/names/n78095330
http://id.loc.gov/authorities/names/n79022909
http://id.loc.gov/authorities/names/n80044566

In this sense, we certainly have a lot of work cut out for ourselves.

Cordially,

Kevin
