| Abstract: | The boundary integration of the gravity anomaly is derived from the gravitational potential by using Gre'en's formula. The boundary integral equation is discretized by the boundary element method.The computing procedure is facilitated by the technique of the co-ordinate system transformation on the cell elements.The modeling results show that the method presented in this paper is valid. |
