There's an interesting audio interview with Tyler Bell on O'Reilly Radar about
how to specify geographical location. In the interview, Tyler talks about
In brief, they define a unique 32-bit number to each location: the "Where On
Earth ID" or "WOEID". They also provide a public, restful API to query their
database to extract metadata about the area. Details are available here:
One of the nice features of this is one can express low-granularity
information (such as a city, county or country) without having to specify a
(potentially meaningless) centroid lat./long. ordered pair. This is nice as
they also expose their semantic structure, so one can (for example) discover
that Canada is within the United States.
I propose in the next version of GLUE we add an optional field called woeid so
people have a standard field to include the WOEID, if they choose to do so.
