摘要
提出了焦作地区GPS高程拟合方法,通过实验研究,建立了该地区高程异常拟合的数学模型,并对该模型拟合结果的正确性和精度进行了评定,结果表明,利用该模型拟合精度高,完全可以代替传统的四等水准测量。
This paper put forward the method of GPS height curved surface fitting for Jiaozuo city, established the mathematic model of height anomaly fitting by experimentation, and assessed the correctness and the precision of fitting result. The result indicated that the model has the high precision and it can replace the fourthly grade leveling.
