What happens when people don't agree on the what makes up each of those elements?
What happens when different groups have conflicting requirements for specificity?

GIS coordinates
Map coordinates
Street address
Region name
A polygon on a map.
Any of the above plus relative coordinates:
10 paces north
a depth of 10 meters
from 10-20 meters in the canopy.
