Abstract

Abstract: In order to solve the problem that the accuracy of GPS elevation anomaly fitting model can't meet the accuracy demand in the complicated terrain conditions in mountainous areas,the ant colony algorithm combined with the multi-surface function method is proposed.Some feature points are got by using ant colony algorithm and the expression of feature points are elaborated to build a more accurate fitting model.Through analysis of the example,it can be seen that the in-accuracy of the fit points in the study area is 2.5.mm,the overall accuracy of the checkpoints is 4.4.mm,and the accuracy of inside and outside matches is higher than that of the conventional fitting model.The results show that the method of GPS elevation anomaly fitting based on ant colony algorithm was feasible and effective.At the same time,it proves that ant colony algorithm has certain advantages in finding the optimal feature point,which has a good reference value for modeling research.
