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 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 کاملLandslide Activity Maps Generation by Means of Persistent Scatterer Interferometry
In this paper a methodology is proposed to elaborate landslide activity maps through the use of PS (Persistent Scatterer) data. This is illustrated through the case study of Tramuntana Range in the island of Majorca (Spain), where ALOS (Advanced Land Observing Satellite) images have been processed through a Persistent Scatterer Interferometry (PSI) technique during the period of 2007–2010. The ...
متن کاملشناسایی، پایش و بررسی سازوکار زمین‌لغزش با استفاده از روش تداخل‌سنجی پراکنش کننده‌های دائمی تصاویر ماهواره‌ای رادار با روزنه ترکیبی
The persistent scattering interferometry (PSI) technique is a valuable tool in displacements' monitoring of earth's surface. The persistent scattering interferometry (PSI) based on persistent scatterrer (PSInSAR) is one of the techniques used to reduce constraints (temporal and spatial incoherency). It is based on persistent scatterer and monitor displacement of only the pixels with timely-cons...
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...
