The PSIG approach to persistent scatterer interferometry [PDF]

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
This paper describes some of the key features of the Persistent Scatterer Interferometry chain of the Geomatics (PSIG) Division of CTTC. The paper firstly provides an overview of the entire PSI chain. It then focuses on the first part of the chain, which provides the input data for the estimation of the Atmospheric Phase Screen (APS). In this part, the

Polarimetric Stationarity Omnibus Test (PSOT) for Selecting Persistent Scatterer Candidates with Quad-Polarimetric SAR Datasets

Sensors, 2020
In the traditional single polarimetric persistent scatterers interferometric (PSI) technology, the amplitude dispersion index (ADI) is usually used to select persistent scatterer candidates (PSC).

Using Persistent Scatterer Interferometry for Post-Earthquake Landslide Susceptibility Mapping in Jiuzhaigou

Applied Sciences, 2022
Earthquakes cause a huge number of landslides and alter the regional landslide risk distribution. As a result, after a significant earthquake, the landslide susceptibility maps (LSMs) must be updated.

Scattered striated persistent nephrogram in sepsis [PDF]

Nephrology Dialysis Transplantation, 2011
Persistent nephrogram, the hallmark of radiocontrast-induced kidney failure, is usually homogenous throughout the kidney and is considered as a generalized shutoff of glomerular filtration, the consequence of altered glomerular hemodynamics, affecting most glomeruli.

Persistent Scatterer Interferometry: A review

ISPRS Journal of Photogrammetry and Remote Sensing, 2016
Persistent Scatterer Interferometry (PSI) is a powerful remote sensing technique able to measure and monitor displacements of the Earth’s surface over time. Specifically, PSI is a radar-based technique that belongs to the group of differential interferometric Synthetic Aperture Radar (SAR). This paper provides a review of such PSI technique. It firstly

The PSIG chain: an approach to Persistent Scatterer Interferometry [PDF]

SPIE Proceedings, 2014
The PSIG procedure is a new approach to Persistent Scatterer Interferometry (PSI), which is implemented in the in-house PSI chain of the Geomatics Division of the CTTC. The PSIG procedure has been successfully tested over urban, rural and vegetated areas using X-band SAR data.

Persistent Scatterer Interferometry (PSI) Technique for the Identification and Monitoring of Critical Landslide Areas in a Regional and Mountainous Road Network

Remote Sensing, 2023
A reliable road network is a vital local asset, connecting communities and unlocking economic growth. Every year landslides cause serious damage and, in some cases, the full disruption of many road networks, which can last from a few days to even months.

Systematic Exploitation of the Persistent Scatterer Interferometry Potential [PDF]

Procedia Technology, 2014
This paper briefly addresses the problem of exploiting the potential of Persistent Scatterer Interferometry (PSI) data. This has always been an open issue with the previous SAR missions. With Sentinel-1 it is becoming even more important due to its high throughput. Current data processing capabilities allow us to process a fraction of the acquired data;

Monitoring Building Activity by Persistent Scatterer Interferometry

Remote Sensing, 2023
In many countries globally, information for new buildings is either scarce or incomplete. In an effort to bridge this information gap an approach based on public domain synthetic aperture radar (SAR) satellite data is introduced. The method is based on the persistent scatterer interferometry (PSI) technique in order to detect newly constructed ...
