摘要
为提高高程联测的工作效率和精度,提出基于EGM2008重力场模型,GPS技术结合似大地水准面的高程联测方法,并在山东地区比较了不同方法拟合高程异常残差的精度。研究结果表明:加权反距离法的拟合标准差为6.3 cm,优于其他方法,高程联测的精度可信。
This paper introduces a fast and accurate method to transfer the elevation of the factory control point. The method is based on gravity field model of EGM2008 and GPS quasi-geoid. With comparison of several fitting methods of height anomaly residual errors in Shandong area, the result demonstrates that the precision of inverse distance weighted method is 6.3 centimeters, which is much higher than that of the others.
