摘　　要：本文主要对西安80坐标系和CGCS2000坐标系(ChinaGeodetic Coordinate System 2000)进行介绍,并对两种坐标系统的转换原理进行研究。利用MATLAB编写基于最小二乘法的布尔沙七参数转换模型,实验结果表明:该方法转换结果精度较高,可满足一般工程使用。The 80 Xi'an coordinate system and CGCS2000 were introduced and the transformation methods of these two coordinate systems were studied.The order of bursa model was compiled by MATLAB and the parameter calcula?tion based on the least square method.The experimental results show that the method has high accuracy and can be used in general engineering.
