Persistent Scatterer Interferometry (PSI) Technique for Landslide Characterization and Monitoring
The measurement of landslide superficial displacement often represents the most effective method for defining its behavior, allowing one to observe the relationship with triggering factors and to assess the effectiveness of the mitigation measures. Persistent Scatterer Interferometry (PSI) represents a powerful tool to measure landslide displacement, as it offers a synoptic view that can be rep...
متن کاملApplication of Persistent Scatterer Interferometry for Land Subsidence Monitoring in Sydney, Australia using ENVISAT ASAR Data
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. ...
متن کاملA Procedure to Map Subsidence at the Regional Scale Using the Persistent Scatterer Interferometry (PSI) Technique
In this paper, we present a procedure to map subsidence at the regional scale by means of persistent scatterer interferometry (PSI). Subsidence analysis is usually restricted to plain areas and where the presence of this phenomenon is already known. The proposed procedure allows a fast identification of subsidences in large and hilly-mountainous areas. The test area is the Tuscany region, in Ce...
متن کاملAn Approach to Persistent Scatterer Interferometry
This paper describes a new approach to Persistent Scatterer Interferometry (PSI) data processing and analysis, which is implemented in the PSI chain of the Geomatics (PSIG) Division of CTTC. This approach includes three main processing blocks. In the first one, a set of correctly unwrapped and temporally ordered phases are derived, which are computed on Persistent Scatterers (PSs) that cover ho...
متن کاملPersistent Scatterer Interferometry Using Adaptive Deformation Models
Because the quality assessment of Persistent Scatterers (PS) is dependent on the deformation model chosen, PS may be falsely rejected due to model imperfections. To accept these PS, more advanced deformation models should be used. However, the decreased rank of the estimation problem increases the chance of unwrapping errors. Therefore, advanced deformation models should only be applied when ne...
