| Abstract: | Refinement of quasigeoid is a hot question in surveying and mapping.And the selection of known points has significant influence on the result of refinement of quasigeoid.So the selection of known points is studied.The traditional manual method,combination of france method and one-by-one elimination method were analyzed and compared.Then it verified the strong points of one-by-one elimination method in practical example.The conclusion has some reference value for practical engineering application. |

| Keywords: | refinement of quasigeoid one-by-one elimination method consistent accuracy selection of known points |
