Based on the introduction of several methods of GPS /leveling geometric fitting and Jinan quasi-geoid re-fine construction project,this paper,taking control survey data of a refuse processing plant as an example ,analyzes and compares the different geometric fitting methods with the results of Jinan quasi-geoid refine which the results calculated by the normal altitude .According to the comparison results and the practical experience ,the present work analyzes the influence factors of accuracy of different fitting methods ,and also focuses on the precautions of field survey ,Finally the principle of the application scope of these GPS/leveling fitting methods is discussed .
