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 ...
