| Abstract | Abstract. An alternative analytical (numerical) method for computing areas of figures of irregular boundary has been developed based on fourth order polynomial approximation. The resulting formula (called Simpson's 2/45 rule) has been tested with actual field data, small-scale map data, and theoretically exact area figures. The results show that Simpson's 2/45 rule is a competitive, and possibly more accurate, method for area computation of irregular boundary figures. |
