| 摘 要： | 探讨了我国原有地方坐标系与CGCS2000坐标系的定义差别,在我国相关学者研究成果的基础上,设计一种基于布尔莎七参数转换模型的坐标系统转换方法,可以实现除高等级大地控制点之外的各种地理信息数据从原有地方坐标到CGCS2000坐标的快速转换。

| Abstract: | It will take our country about 10 years to transform the Original Coordinate system to the CGCS2000 coordinate system.This paper describes the differences between the Xi'an80/Beijing54 coordinate system and the CGCS2000 coordinate system.On the base of the achievement which the other professors made,the author designs a new method which use seven transformation parameters to transform the coordinate system.So we can transform the data of GIS from original coordinate system to CGCS2000 coordinate system. |
