[postgis-users] bounding box

[Jose Gomez-Dans]

Hi Pedro,
> But... how does one obtain a bbox from a set of points?

You can try the ConvexHull function, if you're not only interested in
the extent (as others have pointed out), but in a tight envelope for
your points.

If you mean a list of the different functions implemented by PostGIS,
then Chapter 6 of the docs is useful:
<http://postgis.refractions.net/docs/ch06.html>

Cheers,
Jose
