In this article, the Fredericton approach to deformation analysis is presented. It is possible to use several deformation models to determine the differences between the geodetic observations or ...between the coordinates of points in geodetic network in more epochs. The most appropriate deformation model has been chosen based on statistical testing and available information about dynamics at the area of interest. First, a theoretical background of the approach is described. Then it is applied to the generated observations in two epochs. In the present example, the results of the Fredericton approach differ only slightly from the results obtained with the Delft Karlsruhe in Hannover approaches.
The Delft approach, a method for the deformation analysis, is presented in this article. Based on geodetic measurements, the statistical significance of displacements at the surface is determined ...with statistical methods. A numerical example shows the effectiveness of the presented method.
