| Abstract: | Combining GPS surveying data with leveling data,the height fit is made separately by polyhedral function and conicoid function.The results show that the precision is higher when the height anomaly is fitted by polyhedral function in the area that the change of the height anomaly is larger. |

| Keywords: | height anomaly leveling height fit polyhedral function conicoid function fit precision |
