[postgis-users] convex hull

[Stephen Crawford]

All,

I'm trying to get the polygon outline of a collection of points.  I used 
ConvexHull, and what I got was--hence the name--convex.  Is there a way 
to get a more exact outline?  In my image below, the points are in 
purple and the convex hull is in red.  I want to get a poly that more 
closely matches the points.

Thanks,
Steve
