Abstract:For solving the problems in the subregional riging up of the subregional fitting and transforming GPS height into normal height,this paper uses the generalized extension interpolation method in the large or complex area of to pographic change in GPS height conversion.Practical examples show that,by use of this method, the accuracy of GPS height conversion can be improved and the sudden step change can be avoided as well.
