| Abstract: | Three gravity anomaly gridding methods are introduced and analyzed in this paper. The computation of the lag distance and the semi-variogram are studied in detail. Three methods are compared with different parameters using real gravity anomaly data gridding computation. Results show that there is no great difference in precision. Comparatively, the Kriging method shows the best precision in this area. |
