| Abstract: | The paper discusses transform between Bejing54 and Xi'an80 coordinates system based on the whole differential equation of geodesic. And some improvement has been made in the 3 parameter method and 7 parameter methods. And some requirements to gain the best transforming precision have been gained through the experimentation based on the control survey production in Hubei province. |
