How can we pass from an interferogram in phase to an altitudinal one?

Hi,
I have to find the deformation of a zone between two different dates. In fact, I have generate lots of interferograms with the same master but not the same slave. I have the evolution but all my results are in phase. I want to know how can i convert them from phase to altitude ? Because with it I would observed the evolution of the topography and the deformation between my dates.

Thank’s !

Two steps are required

  1. Unwrapping
  2. Phase to deformation

You do this with all interferograms and then use the band maths or thr pin manager to evaluate them.

Ok, thank you for your answer ABraun. Just another one, for the unwrapping phase I want to export my interferogram in the format : .map , How can I do this ? I don’t find the solution

Thank’s for your time

I don’t know this file type, sorry. Which software makes use of it?
