Abstract

In this paper, we apply small baseline DInSAR technique for the generation of surface deformation maps of the investigated area based on complex network. The technique estimates the linear deformation velocity in wide areas, not only in urban areas but also in suburban areas. The results presented in this study are obtained using 6 SAR data acquired by ENVISAT ASAR during 2004-2006. We compare the results with precise leveling data, which validate our results.
