GNSS RTK高程拟合在市政路网勘察设计中的应用

On application of GNSS RTK height fitting in municipal road network survey design

分析了二次曲面和多项式曲线等高程拟合方法,并根据实际工程,采用GNSS RTK测量方法,分别从不同拟合方法和不同拟合点选取方面,对市政路网工程的应用情况和适应性进行了论述,得出了采用此两类拟合方法能满足图根级GNSS RTK高程拟合精度的结论。

The paper analyzes the height fitting simulation for the quadric surface and polynormal curve,adopts GNSS RTK measurement in projects,indicates the application of the municipal road network projects and adaptability from various fitting methods and selection methods for various fitting points,and concludes the two fitting methods can meet the demands of the GNSS RTK height fitting accuracy of map root level.
