摘要
建国以来,我国先后建立了1954北京坐标系、1980西安坐标系,并于2008年开始启用CGCS2000坐标系,而工程建设上测量常用的坐标系还有WGS-84坐标系以及地方独立坐标系。因此,往往同一测绘区域会用不同的坐标系表示测绘成果,为了能够充分利用不同坐标系的成果,并且使之满足工程建设的需要,不同坐标系之间的成果转换成为测绘工作者经常遇到和必须解决的问题。文章以WGS-84坐标系转换为北京54坐标系实例数据为基础,对不同的坐标系转换模型进行了对比分析以及系统的研究,所得结论可供同类问题参考。
Since the founding of the people＇s Republic of China ,1954 Beijing Coordinate System and 1980 Xi＇an Coordinate System have been established in our country, and the CGCS2000 Coordinate System has been used since 2008. The commonly used coordinate system in engineering construction is WGS-84 Coordinate System and local independent coordinate system. The transforma-tion of the results between different coordinate systems is often encountered and must be solved by surveying and mapping workers. Based on the example data from WGS-84 coordinate system to Beijing 54 Coordinate System, this paper makes a comparative analy-sis and systematic research on different coordinate system transformation models. The conclusions can be used as reference for similar problems.
