摘　　要：根据工程测绘工作的需要,文中用模块化的编程思想、可视化开发语言将测绘常用坐标进行了转换,主要包括从空间向大地坐标系的转换,大地坐标系向平面坐标系的转换,和空间坐标系向平面坐标系的转换和它们之间的逆转换等。文中分别从三参数、七参数、四参数、高斯投影正反算等方面入手,分析阐述坐标系统的转换。In the paper.the coordinates commonly-used in surveying and mapping are transformed with modular programming principles and visual language developed based on requirements of the surveying and mapping engineering.These transforma- tions mainly include transformations from the 3D coordi- nate system to the geodetic coordinate system.from the geodetic coordinate system to the plane coordinate system, from the 3D coordinate system to the plane coordinate sys- tem and the reverse transformations among them.Further- more.these transformations are analyzed and illustrated as well in the paper with regard to the three-parameter formula.seven-parameter formula.four-parameter for- mula and the positive and negative computation of Gaussi- an projection.etc.
