The traditional geographic data, which belong to different geodetic datum frames, make it difficult to manage and share in a common frame. In order to realize the conversion and unification of the data in different datum frames, converting parameters through robust estimation is put forward when the precision index of the two different coordinates cannot be obtained. Through arithmetic analysis, it is proved to be advantageous than the traditional method.
