摘要
针对线路工程的特点,探讨了曲面拟合在丘陵和微山地区似大地水准面精化中的应用,经实例验证:如果拟合点的取样间隔小于5 km,拟合出的似大地水准面可以达到厘米级,以推广该方法的应用。
According to the features of line works, the paper discusses the application of quasi-geoid refinement in hill and low-mountain area. Using the exaznple,it proves that if fitting selection point interval is less than 5 km, the fitting result can meet centimeter scale, in order to promote the application of such method.
