| Abstract: | The methods of continuous curvature splines in tension,minimum curvature and Shepard's method were compared and analyzed using isostatic anomaly data.The results show that continuous curvature splines in tension method has better global properties,higher precision and good result of interpolation or extrapolation in poorly constrained regions. |

| Keywords: | gridding continuous curvature splines in tension minimum curvature shepard |
