| Abstract: | The character and applicability several fitting methods for refining local quasigeoid are systematically analyzed in some examples which have the different area, the terrain complexity, the diverse accuracy of GPS/leveling data and the various resolutions of gravity quasigeoid. Finally,those methods are applied successfully in three typical projects of refining quasigeoid, and the good effects are obtained. |
