Are you simply trying to prove Waldo Toblers' First Law of Geography,
"Everything is related to everything else, but near things are more related
than distant things."?

	     I was thinking a problem: Is there a rule: the same spatial
functions using the same spatial objects are performed regulaly, at least
queries from people living  same area will resulted in such scenes.eg
<http://scenes.eg/> . people in New York will often query area size of
someting in New York, and They are also  more interesting in postion
relationship of buidings in NewYork. I think this conforms to rule of thumb.
But now I hope to approve it with facts. Do you have ever think about this
quesiton and have some statistics on such problem. Can you give me some GIS
trace and I use it to confirm it. 
	bless you!
