| Abstract: | The 2D Vondrak filter combined with the multisurface function was used in the height anomaly fitting.The experimental result shows that it is a practicable method in the height anomaly fitting.Compared with the multisurface function fitting method,the accuracy have been greatly improved to 76.4% at most.The standard error has decreased up to 54.72%. |

| Keywords: | 2D Vondrak filter height anomaly multisurface function least squares mean square error |
