不同公共点对坐标转换精度的影响研究

Influence of Different Common Points on Coordinate Conversion Accuracy

我国历史上曾更换过多个坐标系统,而不同时期的测绘成果又都是基于不同的坐标系统。为了充分使用这些测绘成果,使其发挥最大价值,进行坐标转换是必要的工作。从理论出发,结合实例探讨了不同公共点对坐标转换精度的影响。

Many coordinate systems have been replaced in China’s history,and the surveying and mapping results in different periods are based on different coordinate systems.In order to make full use of these surveying and mapping results and maximize their value,coordinate transformation is a necessary task.This paper mainly discusses the influence of different common points on coordinate conversion accuracy from theory and examples.
