[postgis-users] showing the distribution of locations from a table on a world's map

[XorX xorx]

I've a table with locations from around the world, I'd like to show a kind 
of "index map" that allows users to see the world with an overlay of 
rectangular areas on it showing the number of locations existing inside each 
area. I was thinking in drawing the gist index bounding boxes as those 
rectangular areas and write some SQL to count the number of locations that 
fall within and then draw each area and its number of locations on the map.

Do you think this is a good approach or are some simpler or better way to do 
that? Actually I don't know if getting the gist bounding boxes is possible.

Thanks much.
Jordi
