[sci.math] Algorithm needed to determine if a point is inside a polygon

jmn@cbnewsh.att.com (john.b.medamana) (07/28/90)

I am posting this article for a friend who works in the field of
Urban Planning. 

I am looking for software which determines whether an arbitrary
point lies within or outside a polygon.  Please e-mail or post
replys.

Thanks in advance.
