Application and Research of BM Model in the Elevation Fitting of the Express Way

Abstract:

To improve the precision of GPS elevation fitting and solve the problem of data modeling on elevation of the express way, this paper proposes the BM model. Firstly, this paper introduces mathematical model to GPS elevation fitting, and then fits date with neural network. By this method, BM model can achieve the elevation data modeling about express way and other line-like object. BM model’s structure has been used in the actual engineering data, and the average error can reach 0.0001m, mean square error is 0.0283m. BM model solves the fitting precision’s instability which caused by the uncertainty of geoid.
