[postgis-users] Extent Generation

[Leonardo Mateo]

Hi guys, I'm pretty new with all this GIS thing. I'm gonna need some help.
I need to generate map files dynamically for different spatial
datasets (mostly points) and I don't know how to find out the extent
for each one of these data sets.

For testing, I've been doing this with the help of external tools such
as Quantum Gis or Udig but now I need to do this inside the
application wich will be a PHP web application.

How can I do it?

Thanx a lot in advance.
