SAR interferograms have been largely employed to estimate and interpret the motion of the Earth surface. The aim of this work is to provide a framework that allows the direct interpretation of DInSAR wrapped fringes for geophysical applications. Such measurements can be also be used to retrieve geophysical models parameters. An error analysis is discussed, then the methodology is demonstrated showing the estimation of strain and rotation components of a glacier flow and the inversion of an earthquake fault slips distribution using Okada dislocation model.
