Dear Ralph, thanks for responding; you wrote:

Thanks; I thought it would/should be easy, and
your explanation is in line with my thought
experiment for this project.

Hm, already tried that, but my search criteria 
gave a lot of junque, including one spoof paper 
(that I think I may enjoy reading) by an Oleg 
McOleg.  Would you recommend a specific search 
phrase ('"region tree"+temporal+spatial' didn't 
help) or do you have direct links?

Thanks again for taking time to answer my
questions.
