摘要
在分析高斯投影变形的基础上,针对工程测量中的投影变形精度要求,阐述了3种椭球变换法建立地方独立坐标系的方法,给出具体的计算公式和参数选取原则。对3种椭球变换法进行软件设计,简化计算的工作量。并详细介绍如何求解这些参数和控制点坐标值,结合实例数据进行分析,得到不同方法建立地方独立坐标系的优缺点和适用范围。
Based on the deformation of Gauss-Kruger projection and the requirement of projection deformation ,this paper presents three different ellipsoid-transform metods to establish the independent coordinate system ,specific formula and parameter selection principles .A new software is designed to avoid the shortages of current program and the calculation has been simplified .The details to solve these parameters and control point coordinates value date are analyzed with examples ,and some meaningful conclusions based on different methods are drawn to show the strengths and weaknesses as well as the scope of local independent coordinate system .
