| Abstract: | The height anomaly grid linearity interpolation method can't express a smooth quasigeoid curved surface effectively.Aiming at this problem,this paper presents the machine learning method based on statistical learning theory.Combining with coarse error finding technology and virtual observations,it builds a high precision GPS leveling quasigeoid model.GPS leveling modeling example of Wuhan quasigeoid validates the reliability and advantages of the methods proposed.A series of software,i.e.PC version,WEB version and PDA version are developed successfully,therefore,the Wuhan quasigeoid model can be used widely to maximum extent. |
