摘要
在调兵山地区,选择76个大地高和正常高都已知的点作为原始数据,采用泰勒二次多项式曲面拟合法和泰勒二次多项式曲面加权平均法建立该地区大地水准面,通过实例发现,泰勒二次多项式曲面加权平均法对高程异常的短波项有很好的改进效果,拟合残差比较大的点采用泰勒二次多项式曲面加权平均法残差变小,大大提高了拟合模型的精度。
In Diaobingshan area, 76 points are taken as the original data, a math geoid model is established by taylor polynomial fitting and taylor polynomial weighted average method. Taylor polynomial weighted aver- age method has a better effect in the height anomal shortwave items by example. The residuals are smaller by taylor polynomial weighted average methods, which greatly improves the accuracy of fitting model.
