| Abstract: | The grid resolution of the height anomaly surface simulation based on High Accuracy Surface Modelling(HASM) has been computed in the error theory,thus we can avoid the complicated Taylor expansion and solve the location differences between sampling points and the central points of grid of the simulation surfaces.A certain area was employed to compare the simulation errors between HASM and the classical methods of height anomaly surface fitting.The results show that HASM is much more accurate than the classical methods. |
