摘要
针对试验中对坐标转换的应用范围和精度要求,本文从坐标转换七参数的解算方法、精度评定等方面进行了论述、分析,并结合某试验场区CGCS2000建设,进行了数据精度分析,为今后局域地区坐标转换提供了重要的理论依据。
According to the requirement of the scope of application of coordinate transformation and precision test,calculation method and otrer aspects the seven parameters from the coordinate conversion are discussed,and combined with the analysis,a test field area CGCS2000 building,analysis of data accuracy is analyzed,for the further of local area coordinate transformation provides an important theoretical basis.
