不同坐标系间基准转换精度影响因素研究

Research on the influencing factor of benchmark conversion accuracy between different coordinate systems

基准转换是指不同坐标系间椭球基准的转换。不同坐标系由于采用的椭球参数、定位、定向、尺度等参数的不同而存在基准的差异,为了在不同椭球基准的坐标系之间建立联系必须进行基准转换。文中结合实际算例,分析研究不同坐标系间基准转换的精度影响因素,目的在于指导实际生产应用。

Benchmark conversion was the transform with the ellipsoid reference between different coordinate systems.Different coordinate systems had the different reference differences due to different parameters such as ellipsoid parameters,positioning,orientation,and scale. In order to establish contact between coordinate systems of different ellipsoid references,reference conversion must be performed. In this paper,combining the practical examples to analyze the factors affecting the accuracy of benchmark conversion between different coordinate systems to guide the actual production application.
