Compact text encoding of latitude/longitude coordinates
Methods are disclosed for encoding latitude/longitude coordinates within a
URL in a relatively compact form. The method includes converting latitude
and longitude coordinates from floating-point numbers to non-negative
integers. A set of base-N string representations are generated for the
integers (N represents the number of characters in an implementation-defined
character set being utilized). The latitude string and longitude string are
then concatenated to yield a single output string. The output string is
utilized as a geographic indicator with a URL.
