Multi-temporal Interferometric Synthetic Aperture Radar (MT-InSAR) has been widely used for ground motion identification and monitoring over large-scale areas, due to its large spatial coverage high accuracy. However, automatically locating assessing the state of from massive (InSAR) measurements is not easy. Utilizing spatial-temporal characteristics surface deformation on basis Small Baseline Subsets InSAR (SBAS-InSAR) measurements, this study develops an improved method locate potential...
In recent years, increasing available synthetic aperture radar (SAR) satellite data and gradually developing interferometric SAR (InSAR) technology have provided the possibility for wide-scale ground-deformation monitoring using InSAR. Traditionally, InSAR are processed by existing time-series (TS–InSAR) technology, which has inefficient calculation redundant results. this study, we propose a wide-area variable-scale deformation detection strategy (hereafter referred to as WAVS–InSAR...
Abstract This study monitors the land subsidence of whole Pearl River Delta (PRD) (area: ~ 40,000 km 2 ) in China using ALOS1/PALSAR data (2006–2011) through SBAS-InSAR method. We also analyze relationship between and coastline change, river distribution, geological structure as well local terrain. The results show that (1) with average velocity 50 mm/year occurred low elevation area front part delta coastal area, regions subsiding faster than 30 2006 2011 is larger 122 ; (2) order estimated...
The Sentinel-1A/B satellite launched by European Space Agency (ESA) in 2014 provides a huge amount of free Terrain Observation Progressive Scans (TOPS) data with global coverage to the public. TOPS have frame width 250 km and been widely used surface deformation monitoring. However, traditional Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) methods require large computer memory time when processing full resolution long strips. In addition, they hardly correct atmospheric...
Abstract This study monitors the land subsidence of whole Pearl River Delta (PRD) (area: ~40,000 km 2 ) in China using ALOS1/PALSAR data (2006-2011) and SBAS-InSAR method. We also analyze relationship between coastline change, river distribution, geological survey as well geomorphology data. The results show that (1) with average velocity 50 mm/year occurred low elevation area front part delta coastal area; (2) areas along rivers suffered from surface subsidence, due to fragile structure...
