高速公路不同坐标系间坐标转换的方法研究

Research on Coordinate Conversion Methods Between Different Coordinate Systems on Freeway

不同坐标系间的坐标换算是高速公路设计中一个专业性强且难以解决的问题。本文就其产生的原因、计算原理、方法等进行了探讨,提出了该问题的几种解决方法及使用条件和应用对象,并进行了横向比较及实例验算。

Coordinate conversion between different coordinate systems is a problem in freeway design whic has strong speciality and is difficult to be solved. The paper makes an approach to its reasons, computing principles and methods,and puts forward some of solutions,using conditions and application objects to the problem,moreover conducts transverse comparison and example checking computation.
