Deformation analysis between epoch 1+2+..k-1 vs epoch k

Hello,

I'm just thinking about the reliability meaning of z (mm). Is the reality of z(mm) > alowwable maximum displacement for the object point.

The reliability of the estimated coordinate components is derived by the observations and the stochastic model and depends on you network configuration. The shift or displacement of an object point can be simple verified. An object point should be defined twice in the JAG3D project, i.e. one-times per epoch. Thus, the shift is estimated by subtracting the values from each other. The related uncertainties of the shift-parameters are derived by applying the propagation of uncertainties.

kind regards
Micha
