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

Hello,

But my project, all of reference points outside the dam and object points on the dam are moved vs epoch 0. I want to detect the shifts of the block vs epoch 0.

If all reference points are shifted in the same direction and order of magnitude, the differences between the centroid of the reference points of epoch 0 and the centroid of the reference points of epoch k describes the shift parameters.

To proof that all reference points are shifted in the same direction and order of magnitude, you have to compare the internal configurations/geometries of the network in both epochs. This can be done by JAG3D in a normal congruence analysis.
