摘要
GNSS定位结果属于协议地球地心坐标系,现实测绘中,通常需要国家平面坐标。如何有效地转换坐标成果,一直是个难题。文章在简单分析了坐标系及坐标系转换基本原理的基础上,结合坐标转换基本模型提出了不同坐标系之间坐标转换的两种思路,并给出转换流程及具体步骤,得出一些有益的结论,有助于初学者及众多测绘人员或其他专业技术人员更好的使用GNSS。
The observation achievements of GNSS are represented Conventional Terrestrial System, but in the actual surveying, we need the national horizontal coordinates. How to transform the coordinate achievements effectively is a difficult problem. This paper simply analyzes the basic principles of the transformation of coordinates in the foundation of introducing several kinds of coordinate systems, combines the basic coordinate transformation model which puts forward two kinds of coordinate conversion between different coordinate systems and presents a transformation process and the specific steps, which have contributed to use GNSS measurements easily for beginners and mapping workers or other professional and technical workers.
