RTK测量技术中的坐标转换方法研究

摘要

Global positioning system (GNSS) are introduced in the application of surveying and mapping work, tells the sto-ry of the RTK technology to obtain the WGS84 coordinate transformation to the local coordinates, the method of combina-tion with the engineering data for the study of coordinate transformation, it is concluded that the three parameters, four and seven parameters of coordinate conversion method of the application scope and conditions of use.%介绍了全球卫星定位系统（GNSS）在测绘工作中的应用发展历程，讲述了采用RTK技术获取的WGS84坐标转换到地方坐标的方法，结合工程数据进行了坐标转换研究，得出了三参数、四参数及七参数坐标转换方法的应用范围及使用条件。
