Related, but not in answer to the recent post by Xiandong Liu on map
projections.

Are there any publicly available datasets like that used to describe
countries in WorldMap? Where, for instance, could one find the map
coordinates of the US that included the state boundaries, or even described
the perimeter of Long Island in at a finer level of measurement? And
continuing on this topic, just what level of measurement *is* used to
describe the fractal boundaries between countries in Mathematica? ... and is
the same "ruler" used to measure the border of Gibraltar as, say, Australia?
(I assume that the answer to the latter question must be YES or it is a bit
hard to see how bordering countries are going to fit together nicely in a
combined plot.
