Hello Jokin,

I am wondering if JAG3D is capable of checking deformations with only the coordinates of two different epochs including their variances.

JAG3D needs the observations to carry out a deformation analysis. It doesn't use the so-called coordinate method where the coordinates of two different epochs and their covariances are included.

To derive deformations, include the observations of two epochs and allocate the observation groups. Define your (assumed) stable points ones and your object points twice, one for each epoch. Running a free adjustment and derive the coordinates and the possible deformation. JAG3D used the so-called observation method during a deformation analysis.

kind regards
Micha
