Abstract : Methods for calculating the moments of an arbitrary polygon and for determining whether a point lies within a polygon are discussed. The methods are efficient, robust, concise, and easily programmed in any computer language. A FORTRAN 77 subroutine which calculates the first three moments of an arbitrary polygon is also included, as is a subroutine which determines whether a point lies in an arbitrary polygon. Keywords: Polygons; Computer programs; Panel methods; Canada.
