摘要：

In this paper, multinomial curved surface fitting method is used to analyze the feasibility of the GPS leveling height fitting and applicability of all kinds of models in depth. With project cases, according to the comparison and analysis based on fitting precision evaluation and the criterions of model optimization, the main applications and particular analysis methods of fitting model optimization is revealed, by which means the optimal model for the certain surveyed area is offered, conclusions of practical meaning are given, which could have positive influence on GPS practical industrialization.
