建立抵偿坐标系统解决长度变形的探讨

Establishment of Compensating Plane Coordinate Sytem to Tackle Length Deformation

根据测量中长度变形的具体情况分析引起长度变形的因素,阐述了建立抵偿坐标系统解决长度变形的方法,主要有确定抵偿投影面高程和新椭球参数,将原坐标换算到抵偿坐标系等.进行了算例分析,并验证了该方法的正确性.

Based on the specific situations of length deformation in surveying, this paper analyzes the factors causing length deformation and elaborates on the method of establishing the compensating plane coordinate system to tackle the lenth deformation, mainly inclusive of defining the compensatory projective plane elevation and new ellipsoidal parameters and converting the original coordinate into the compensating plane coordinate system. The algorithm analyses are carried out and the correctness of the method is verified.
