Study on the new methods of cross-ocean bridge based on elevation leveling

HUA Xiang-hong1,2,XU Cheng-quan1,2,FAN Qian1,2(1.School of Geodesy and Geomatics,Wuhan University,Wuhan 430079,China;2.Hazard Monitoring and Prevention Research Center,Wuhan University,Wuhan 430079,China)  
The new methods of GPS cross-ocean leveling based on height anomaly difference are put forward.The theory and data processing design of new methods obtaining elevation anomaly difference using vertical deflection,the SVM(support vector machine),and the neural network respectively are given.Through the practical analysis,the height anomaly difference fitting method based on vertical deflection is suitable for the elevation transmission within the distance of 5km or so.As for the height anomaly difference fitting method based on modeling,if used in plain area,and taken the SVM(support vector machine) as tools to fit the height anomaly difference,its cross-distance can extend as long as 30 km if there are enough points both used as GPS and leveling points,and the distribution is reasonable.Adopting neural network to fit the height anomaly difference,it would only be suitable for the elevation transmission of 10km or so.
