摘　　要：尝试将工程科学中的广义延拓逼近法应用于高程拟合,此法综合了插值和拟合两种数值方法的优点。通过对地形平坦和地形起伏较大两种测区的GPS水准点进行高程拟合,并分别与传统的多项式曲面拟合法和多面函数拟合法得到的精度结果进行比较分析,验证了此法的可行性,得到了一些有意义的结论。The thesis uses the generalized extended interpolation method in GPS height fitting. The method is based on the interpolation and fitting On flat terrain and topography fluctuation, two measurement of GPS leveling points elevation fitting, and respectively with the conventional polynomial surface fitting method and the polyhedral function fitting method to get the result comparison analysis, verify the feasibility of this method, some meaningful conclusions are obtained.
