Persistent scatterer interferometry (PSI) is a group of advanced interferometric synthetic aperture radar (SAR) techniques used to measure and monitor terrain deformation. Sentinel-1 has improved the data acquisition throughout and, compared previous sensors, increased considerably differential SAR (DInSAR) PSI deformation monitoring potential. The low density persistent (PS) in non-urban areas...

The standard application of multi-temporal, Persistent Scatterer (PS) synthetic aperture radar differential interferometry (DInSAR) techniques to the Caramanico area posed considerable problems linked to the low density of PS [1]. The application of an optimised PSI approach [2], together with an alternative, classification-based PS candidate detection method [3,4], allowed obtaining sets of PS...

Ground subsidence is one of the key factors damaging transportation facilities, e.g., road networks consisting of highways and railways. In this paper, we propose to apply the persistent scatterer synthetic aperture radar interferometry (PS-InSAR) approach that uses highresolution TerraSAR-X (TSX) imagery to extract the regional scale subsidence rates (i.e., average annual subsidence in mm/year...

Abstract. Differential Synthetic Aperture Radar Interferometry (DInSAR) allows displacements to be detected with millimeter accuracy as well more advanced methods, such Persistent Scatterer (PSI). Sentinel-1 data have been collected systematically under the COPERNICUS program at a high temporal resolution global coverage, helping us build wide user community and develop miscellaneous SAR-based ...

As a World Cultural Heritage site with sacred landscape featuring an exceptional range of Buddhist art and architecture, much attention has been focused on the sustainable development Bagan (Myanmar). Particularly, monitoring surface subsidence monument instability is great importance to protection planning heritage site. In this study, we applied high resolution TerraSAR-X imagery acquired fro...
