| Abstract: | The common used coordinate transformation models are introduced and the ellipsoidal height errors' influence in applying Bursa coordinates transformation model is discussed. Considering the engineering application and detail analysis,the two dimension transformation model in coordinate transformation between Beijing coordinate system and Xi'an80 coordinate system is applied, and the results meet the engineering requirements. |
