基于两种模型的GPS水准拟合软件系统的开发

GPS水准在工程实践中仍然以数学拟合方法为主。简述了移动法曲面模型和克里格(Kriging)统计模型的原理。移动曲面法具有连续性,如果找不到多于6个点参与内插,用程序实现自动选择Kriging方法,把二者结合起来称为综合法。Kriging具有无偏最优的统计性质,两种模型在实践中应用较多,为此开发了基于两种模型的GPS水准拟合软件系统,该软件系统可对拟合结果作精度评价。

The Development of GPS-leveling Fitting Software System Based on Two Models

GPS level in engineering practice still gives priority to mathematical fitting method. This paper expounds the principles of the mobile surface model and Kriging statistical model. The mobile surface method has the continuity,if you can＇t find more than six points to participate interpolation, Kriging method is automatically selected by computer program, combining the two methods is called synthetic method. Kriging has unbiased optimal statistical properties. The two models are applied in practice more, therefore GPS-leveling fitting software system is developed based on the mobile surface model and Kriging statistical model, which can give precision evaluation on the fitting results.
