[postgis-users] Problem finding the center of an irregular polygon

[Mikhil Masli]

Thanks a lot, Ben. I was looking for a more algorithmic solution. May be,
the way ST_PointOnSurface is implemented would help? I want to implement
such a solution in a clientside utility like, say, Flash. I was wondering if
GIS folks on this list would know of a solution.
