摘要
利用哈尔滨市区及周边17个水准点GNSS/水准数据,与EGM2008模型所计算的高程异常进行对比,对模型计算的高程异常进行改正,得到精度达到0.05 m的高程异常值。
Using the data of 17 GNSS / leveling points in Harbin and its surrounding,the height anomalies given by the EGM08 are corrected. After the local quasi geoid was built,the height anomaly accuracy can be 0. 05 m at every point.
