RFC 1876 already has a -very- cool method for injecting ambiguity.
>From the RFC:
SIZE The diameter of a sphere enclosing the described entity, in
centimeters, expressed as a pair of four-bit unsigned
integers, each ranging from zero to nine, with the most
significant four bits representing the base and the second
number representing the power of ten by which to multiply
the base. This allows sizes from 0e0 (<1cm) to 9e9
(90,000km) to be expressed. This representation was chosen
such that the hexadecimal representation can be read by
eye; 0x15 = 1e5. Four-bit values greater than 9 are
undefined, as are values with a base of zero and a non-zero
exponent.
Since 20000000m (represented by the value 0x29) is greater
than the equatorial diameter of the WGS 84 ellipsoid
(12756274m), it is therefore suitable for use as a
"worldwide" size.
You don't -have- to go to the nearest coordinate intersection for ambiguity.
