| Abstract: | In the GPS height conversion, it is unable to obtain high accuracy only using surface fitting method and there exist great risk by using BP neural network. To solve the problems, six kinds of combination methods based on the surface fitting and neural network are designed.These methods are compared and analyzed through one example. The results show that the accuracy of the six combination methods are higher than by use of single surface fitting method or BP neural network method, especially the three input surface fitting method has highest accuracy. |
