Abstract
In this paper,the data sources is from the fourth order GPS control surveys in Hengyang City.Through the comparison of the position change rule between standard elevation and the GPS fitting elevation interpolation,it analyzes a standard elevation fitting distribution to the GPS network point elevation precision influence,simultaneously confirms the GPS fitting elevation the reliability.According to change rule of mutual difference,it may provide the reference for the design of leveling routes.
