Yes, I was confused about this. Mea culpa.

So really people should only be linking to and from zones generally.

I've known ppl to do stranger things.

Yup I was confused.

Ok, and if those graphic/@coords are relative to the surface, how do we on the 
surface indicate what unit of measurement they are using?  Surely a surface may 
be measured in all sorts of units (millimetres, inches, metres, 
kilometres,etc.)?  How do I know that one graphic is higher resolution than the 
other?  i.e. they both cover the same area of the surface "0 0 100 100" but one 
was taken with a hi-res camera, and one was taken quite awhile ago with some 
low-res camera.  How is that resolution indicated?

Yes, greatly.  Don't think I've got it entirely.

Best,
