摘　　要：针对三维空间和高程未知的二维空间之间的七参数的求解问题,提出了一种新的高程趋近法,以真实数据和模拟数据证明了其可行性。For the solution of the seven transformation parameters between three-dimentional space and two-dimentinal space without elevation,a new method called elevation approach method is put forward.The feasibility of this method is proved through processing the real data and the analog data.Elevation approach Method can be used in the data transformation of large-scale in the geodetic datum modernization.
