Monitoring slow ground mouvements around Tunis City by different SAR interferometric measures

This paper presents an application of DInSAR techniques for the assessment of ground subsidences around Tunis City. A longterm analysis using two interferometric techniques were carried out to attempt reliable measurements. In this work, some aspects of interferometric processing softwares are reviewed and possible improvements are proposed in order to get better results. The convergence of the two different interferometric techniques done simultaneously and independently confirms results accuracy.
