In this work, we investigate the temporal evolution of ground deformation affecting the ocean-reclaimed lands of the Shanghai (China) megacity, from 2007 to 2016, by applying the Differential Synthetic Aperture Radar Interferometry (DInSAR) technique known as the Small BAseline Subset (SBAS) algorithm. For the analysis, we exploited two sets of non-time-overlapped synthetic aperture radar (SAR)...

Differential SAR interferometry (DInSAR) is an unique tool for low-cost, large-coverage surface deformations monitoring. As well known, the technique involves interferometric phase comparison of SAR images gathered at different times and has the potential to provide millimetric accuracy. Though temporal decorrelation and atmospheric dishomogeneities strongly affect interferogram quality, reliab...

Climate change in the Arctic region is more significant than other parts of our planet. One manifestations these changes crater creation with blowouts a gas, ice and frozen soil mixture. In this context, dynamics studies long-term heaving mounds that turn into craters as result are relevant. A workflow for detecting assessing anomalous regions proposed. Areas increase ALOS-2 PALSAR-2 synthetic ...

Ningdong coal base area located in northwestern China is one of the largest coal-producing bases China. The aim this work to investigate a regional-scale mining subsidence over area, by using both conventional and advanced Differential Synthetic Aperture Radar Interferometry (DInSAR) methods. Fifteen L-band SAR images from ALOS-2 satellite 102 C-band Sentinel-1A spanning between November 2014 J...
