武汉绿地中心超高层建筑平面控制网的建立

Establishment of Horizontal Control Network for Wuhan Greenland Center Ultrahigh-rise Building

以全球导航卫星系统(GNSS)与测量机器人(Georobot)两大技术建立控制网,分析了两种数据(GNSS与Georobot)的误差来源,并进行对比,两者在控制点间高差不大时,得到的结果基本一致。

We used GNSS and Georobot techniques to establish the horizontal control network in this paper. And then, we analyzed and contrasted the error source of GNSS and Georobot data. The result shows that the results for both techniques are nearly the same, when the height difference between control points is small.
