Latitude and Longitude are problematic as identifiers for position, since everyone must agree on rounding and allow for truncation.  There is a systematic way "around" this, if you'll excuse the expression.

The calculation is simple.  The java script is here[1], made for my Australian friends.

Mathematically, it's a useful cheat.  One cannot normally sort timestamps, or rather to do so invites multiple realities, something best avoided before morning coffee.  This algorithm calculates a decimal value of the code used to represent a place, and does a linear transformation of scales to generate a unique HH:MM:SS value for the identifier (a scale of integer seconds).  This method is not statistically valid, but it is *graphically" valid, which is all that is required to solve the problem from an engineering perspective.

The Semantic Web will be unnecessarily complex if the symbols for things have to be translated to the concept for things on the fly.  See also[2].
