Monitoring and analysis of ground subsidence in Shanghai based on PS-InSAR and SBAS-InSAR technologies [PDF]

Scientific Reports, 2023
Shanghai is susceptible to land subsidence due to its unique geological environment and frequent human activities. Traditional leveling techniques are not sufficient for monitoring large areas of land subsidence due to the time-consuming, labor-intensive,

Land Subsidence Monitoring Method in Regions of Variable Radar Reflection Characteristics by Integrating PS-InSAR and SBAS-InSAR Techniques

Remote Sensing, 2022
In the InSAR solution, the uneven distribution of permanent scatterer candidates (PSCs) or slowly decoherent filtering phase (SDFP) pixel density in a region of variable radar reflection feature can cause local low accuracy in single interferometry. PSCs

Land Subsidence in Qingdao, China, from 2017 to 2020 Based on PS-InSAR. [PDF]

Int J Environ Res Public Health, 2022
Land subsidence is a global geological disaster that seriously affects the safety of surface and underground buildings/structures and even leads to loss of life and property. The large-scale and continuous long-time coverage of Interferometric Synthetic Aperture Radar (InSAR) time series analysis techniques provide data and a basis for the development ...

Can Machine Learning and PS-InSAR Reliably Stand in for Road Profilometric Surveys? [PDF]

Sensors (Basel), 2021
This paper proposes a methodology for correlating products derived by Synthetic Aperture Radar (SAR) measurements and laser profilometric road roughness surveys. The procedure stems from two previous studies, in which several Machine Learning Algorithms (MLAs) have been calibrated for predicting the average vertical displacement (in terms of mm/year ...
