Simpson’s Rule Sum of Grids Method Trapezoidal Method All assume that the land is a straight line between the spot heights

Simpson’s Rule Simpson's Rule attempts to allow for the natural shape of the land.

AN ISOMETRIC VIEW

Trapezoid Rule If there were an even amount of spot heights the next best options would be to use the Trapezoid rule to finish of the calculation as show on the next page.
