摘要
为了检核基于CGCS2000椭球建立的广州2000坐标系是否与基于1954北京椭球建立的广州坐标系无缝衔接,采用广州市新CORS系统数据和广州市已有地铁框架网、全面网数据两种方法证明了广州2000坐标成果与广州坐标成果的较差在±5cm以内,二者坐标成果平稳过渡,为其他城市建立2000坐标系提供了很好的借鉴。
In order to check whether the Guangzhou 2000 coordinate system is seamless to the Guangzhou coordinate system, we put forward two methods of using Guangzhou new CORS system and metro frame network and comprehensive network to prove that the result difference between Guangzhou 2000 coordinate system and Guangzhou coordinate system was less than 5 cm. The results of the two coordinate systems are smoothly transition. This study can provide a good reference for other cities to establish the 2000 coordinate system.
