摘　　要：相关人员对坐标转换问题已经研究了较长时间,而测绘技术的快速发展使得测绘与人们的日常生活越来越紧密。全球测绘数据一体化已经形成,这就要求各种坐标系下的测绘数据要统一。本研究介绍了坐标转换过程中涉及的多个关键步骤,并且根据各种坐标转换模型,利用C++编程完成了坐标转换系统的实现。重点是对四参数、七参数的解算,以及相关坐标转换,经测试转换后的坐标能满足一定的精度要求。Coordinate transformation has been studied for a long time,and the rapid development of Surveying and mapping technology makes surveying and mapping more and more closely related to people's daily life.The integration of global surveying and mapping data has been formed,which requires the unification of Surveying and mapping data in various coordinate systems.This study introduces several key steps involved in the process of coordinate transformation.And according to various coordinate transformation models,the coordinate transformation system is realized by C++ programming.The emphasis is on the calculation of four and seven parameters,and the transformation of the coordinates,and the coordinates after transformation can meet certain accuracy requirements.
