InSAR’s capabilities have been considerably improved by advanced processing techniques such as Persistent Scatterer Interferometry (PSI) and SAR Tomography (TomoSAR). However, complicated scattering situations (e.g. layover) need to be better resolved in urban areas. This paper presents a new technique for providing the 3D point scatterer location and the resolution cell configuration, based on...

In the absence of systematic structural monitoring to support adequate maintenance standards, many existing infrastructures may reach unacceptable quality levels during their life cycle, resulting in significant damage and even potential failure. The metropolitan area Gulf Salerno (Italy), served by a complex multimodal transport network connecting port roads railways surrounding urban area, re...

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 ...

The new class of meter-resolution spaceborne SAR systems (TerraSAR-X and COSMO-Skymed) offers a tremendous improvement in interferometric monitoring of urban areas and man-made infrastructure. The high resolution fits well to the inherent scale of buildings (floor height, distance of windows, etc.). In particular, Persistent Scatterer Interferometry (PSI) benefits substantially from this new da...

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...
