[postgis-users] Build polygons from points

Check out the CGAL lib. It should be able to do what you ask.

Subject: [postgis-users] Build polygons from points


Say I have 500 points that represent an area and I'm hoping to build a
polygon out of those points.  Is there a good function to do this in postgis
or a good program that anyone has written that can accommodate this?
Obviously there is no "perfect" method of building polygons from points, but
a function that accepted some inputs (like concavity 0-10 or something,
similar to the way Simplify works?) would seemingly help me refine the
"perfect' method for my purposes.

Thanks,
Galen
