The Tehran basin has been increasingly affected by subsidence during the last few decades due to groundwater withdrawal. Hence, study of strength power towers (PTs) transmission lines, as vital structures, is an important subject. In this paper, persistent scatterer interferometry (PSI) method was applied on data stacks from two satellites (i.e., X-band COSMO-SkyMed (CSK) and C-band Sentinel-1A...

In this paper we demonstrate some benefits of using polarimetric data in persistent scatterers interferometry (PSI). A polarimetric optimization approach is applied to TerraSAR-X dual-pol data, leading to a significant increase in the number of persistent scatterer candidates (PSCs) selected by the most commonly used criteria of quality, namely the amplitude dispersion index and the average int...

The aim of this research is to investigate the terrain deformation in the metropolitan area of Sydney using multiple satellite radar imagery. The persistent scatterer interferometry (PSI) strategy developed at Geodesy and Earth Observing Systems Group (GEOS) of the University of New South Wales (UNSW) is used to map the land deformation in Sydney with C-band ENVISAT radar images in this study. ...

Climate change represents an important cause of subsidence, especially in coastal cities affected by changes surface water level and table. This paper presents a complementary study Interferometric Synthetic Aperture Radar (InSAR) Ground Penetrating (GPR) for the early detection subsidence sinkhole phenomena. The methodology was applied to urban area Galicia, northwest Spain (humid region), sho...
