# Deformation analysis (Software)

Good Morning Gentlemen.

Question:

I want to perform deformation analysis.

Data:

Two set of observation of 20 common points.

Each set consist of slope distances, horizontal directions and zenith angles.

Each set of observation created from 3 stations.

Theses stations are different for each set.

This mean : these are no common stations in a sets only measured points are common

(the station from where measurements are taken are different between sets.)

Question:

How to describe this scenario for deformation analysis in JAG3D ?

(Tutorial show examples where measurements are taken from common datum points.

In my scenario all measurements are taken from unknown points.)

1) Can this scenario be analyzed by JAG3D ?

2) If can how to describe it. Which points are datum, which are new and which are reference ?

I calculated each individual epoch with JAD3D separately. Now I want to combine them together.

During individual epoch calculation I defined each station as new point (unknown), each measured point as datum point, there was no reference or stochastic points. When I tried similar approach for combined data sets JAG3D would not converge or it will calculate solution with huge errors.

Kind regards.
