Detection of Differential Settlement of Man-Made Structures Coupled with Urban Development by Using Persistent Scatterer Interferometry (PSI)

Remote Sensing, 2018
Many cities are prone to land subsidence, particularly due to the overuse of ground water. However, because man-made structures are normally built upon foundations that are stiffer than the surrounding ground, such structures react to land subsidence to a lesser extent.

TXT-tool 4.039-3.2: How to Assess Landslide Activity and Intensity with Persistent Scatterer Interferometry (PSI): The PSI-Based Matrix Approach

2018
This paper provides a step-by-step analysis and discussion of the ‘PSI-based matrix approach’, a methodology that exploits ground deformation velocities derived through Persistent Scatterer Interferometry (PSI) for the assessment of the state of activity and intensity of extremely to very slow landslides. Two matrices based on historical and recent PSI

Updating landslide inventory maps using Persistent Scatterer Interferometry (PSI)

International Journal of Remote Sensing, 2011
This work illustrates the contribution of persistent scatterer interferometry (PSI) from radar satellites ERS (European Remote Sensing satellite) and ENVISAT (Environmental Satellite) for the updating of a pre-existing landslide inventory (LSI) map: the main purpose is to change or confirm the landslide state of activity and geometry and to identify ...

Persistent Scatterers Interferometry Hotspot and Cluster Analysis (PSI-HCA) for detection of extremely slow-moving landslides

International Journal of Remote Sensing, 2011
The synthetic aperture radar SAR interferometry InSAR technique has already shown its importance in landslide mapping and monitoring applications. However, the usefulness of traditional differential InSAR applications is limited by disturbing factors such as temporal decorrelation and atmospheric disturbances.

Health monitoring approach for transport infrastructure and bridges by satellite remote sensing Persistent Scatterers Interferometry (PSI)

Earth Resources and Environmental Remote Sensing/GIS Applications XI, 2020
The satellite PSI Interferometry is a radar-based remote-sensing technique, which is capable of monitoring and measuring displacements with a high precision of the Earth’s surfaces by means of multi-temporal acquisitions. These are collected without interfering in any way with the operating conditions of the transport infrastructure as opposed to the ...

Monitoring soil deformation using Persistent Scatters Interferometry (PSI) technique: The case study of Thessaly prefecture (central Greece)

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The aim of this study is dealing with the use of Persistent Scoters Interferometry (PSI) technique to detect soil deformation. The main idea is to find out point candidates in the agricultural fields in the northern part of Larissa having the properties that PSI technique uses. The soil properties have been classified into five orders. Inside each soil

Multi-Temporal Analysis of Land Subsidence in Toluca Valley (Mexico) through a Combination of Persistent Scatterer Interferometry (PSI) and Historical Piezometric Data

Advances in Remote Sensing, 2014
The Toluca Valley Aquifer (TVA) is considered one of the most overexploited aquifers in Mexico because of the high rate of groundwater extraction for supplying urban and industrial water to Mexico City and Toluca City, which causes land subsidence in ...
