Summary: Natural language coordinate systems convey semantic information
	 about the nature of movement or orientation.


In reviewing whether in California the nature of a coorindate system,
whether Los Angeles is north or northwest of San Diego, or whether orientation
is made off highways or mountains, it is necessary to understand the properties
associated with the coordinate system, and the tools available to measure it.

In recognizing what directions in a context specific setting mean, it is
necessary to understand all the relative directions and distances that the
situation supports, and  the concepts of primary significance of objects in
the orientation.

  you believe to be (R,Th) and SHORTLY you will reach the point at which you
  should be able to IDENTIFY Y.
