Specific analysis on quasigeoid fitting model in linearly region

SHAO Cai-jun(Shaoxing College of Liberal Arts and Technology,Shaoxing 312000,China)  
The paper firstly introduces the elevation fitting principle and common fitting model used in linearly region.Taking the linearly region engineering as an example,it analyzes multiple fitting and three-times sample fitting.Analysis results show that: three-time curve fitting accuracy is high,while three-times sample curve fitting calculation method is complicated,and is suitable for long distance fitting.
