Don,

As you develop the VRML geo-reference model, you will want to 
stay abreast of the same kind of work being done for the SEDRIS
project (www.sedris.org).  As you probably know, Paul Birkel has
written a SEDRIS GRM document, and could provide you some valuable
pointers to the future, as SEDRIS becomes a standard.  You will find
a summary of the SEDRIS GRM on:

Regards, Reed
