| Abstract: | Taking the quas-igeoid model establishment of some certain borderland as an example,we study the Stokes' removing and renewing method and the frame restrict spherical harmonic expanding model.The compution of the area with sparse and unqualified data analyzed.We proved that the realized restrict spherical harmonic expanding model is better than the general Stokes' removing and renewing method in precision. |
