摘要
GPS高程拟合相对于传统的水准测量而言,更加简便地实现大地高和正常高之间的转换,使高程测量的工作效率有效提高。本文结合工程实例,采用多点拟合求解GPS高程,用多面函数拟合法和常规水准测量进行了精度比较,论证了高程拟合在公路勘察中的可行性。
Compared with the leveling surveying,GPS height fitting is more convenient to realize the ellipsoidal height transformation to obtain normal height which can improve work quality and efficiency. Combined with the engineering example,the GPS elevation was deduced with the method of multi-point fitting,and the precision of polyhedral function and conventional leveling was compared. The result demonstrated that elevation fitting feasibility in highway survey.
