It appears that I may need to add something more for rectangular areas -

Michael e-mailed me with some comments much the same as Roger for the rectangle area - Unfortunately Michael's e-mail address was not one I could respond to (could not be delivered - so if you need to register send again).

The other thing to keep in mind when using it is either NS-EW in the lat/long or +- for ns-ew designation - that's one nice thing about the geological reference - it helps define this.

So I'll add a few more fields later for the rectangle definition (which I actually like to use too)
