dc.description.abstract | In Conventional Deformation Analysis (CDA), at least two different epochs are
adjusted by using the Least Squares Estimation (LSE) method and compared statistically.
The effect of the geometry of the network is an essential part of the adjustment model and
the LSE method smears the effects of the displaced point over the other nondisplaced
points. In this study, to remove these spoiling effects and to increase the reliability of the
deformation analysis, a new approach is introduced. This approach depends on the
analysis of the differences between observations of the two epochs, and also considers the
principles of the model error approach. All possible combinations of the differences of the
observations are considered as model errors in Gauss-Markov model and the estimated
model error for the combination, that has the smallest variance, is compared with
a critical value to answer the question whether it is significant or not. To compare the
results of the new approach with the CDA, the Monte Carlo simulation technique and
mean success rate are used in a leveling network. As a consequence, according to the
simulation results, the new approach is better than the CDA by 7.6% and 9.7% for one
and two displaced points, respectively, when the deformation network is designed as
a subnetwork. | en_US |
