摘要
GPS定位技术在交通工程平面控制中得到广泛应用,为使GPS高程成果也可以适用于带状交通工程,则GPS高程拟合模型的选取成为工程应用中急需解决的问题。针对模型的选取,该文试着将二次曲线拟合法与二次曲面拟合法进行对比,并结合某段带状交通工程GPS测量数据进行对比分析,最后得出二次曲面拟合模型拟合效果更佳的结论。
GPS elevation fitting technology has been widely used in traffic engineering,and zonal GPS elevation fitting model has become an urgent problem to be solved in engineering application.In this paper,the quadratic curve fitting method and the quadratic surface fitting method have been compared,and combine the data of a band of traffic engineering to analyze the experiment.Finally,some useful conclusions are drawn.
