An idea . . .
Sort the database return by the area of the BBOX, with smallest area
first, the first row returned with be the smallest, reverse the sort for
the largest BBOX.
If you are using a Imagemap in the client, the sorting still matter,
since you can effectively stack the output of the imagemap in the same
way. The first item in the imagemap stacking that satisfies the browser
will be read and displayed.

Hi folks,
I display several boundingboxes on a map from a PostgreSQL database.
There is a big boundingbox which contains several
smaller boundingboxes.
The User can click on each boundingbox to retrieve further information
of the boundingbox.
The Problem now is that the user also retrieve the information
of the big boundingbox and not only this of the small ones.
Maybe someone can help me solving this problem?
Thanks a lot,
Florian Thuerkow
