LAND SUBSIDENCE MONITORING IN DEZHOU CITY BASED ON SBAS-INSAR TECHNOLOGY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Abstract. To monitor the large area land subsidence in Dezhou city, Shandong province, China. This paper uses 23 scenes of Sentinel-1A radar images from August 2017 to February 2019, and based on small baseline subset (SBAS) technology to obtain the subsidence information in Dezhou urban area. The monitoring results show that: Dezhou city has a serious

Exploring local relationships between SBAS-InSAR Data and Groundwater Level
, 2023 This paper endeavours to evaluate if the relationship between the groundwater variation and the surface movement can be remotely detected in the Punjab, India. Monitoring by proxy the groundwater reserves is a high-stake objective as well for scientists as governmental agencies, and Synthetic Aperture Radar (SAR) data has the advantage to be free of ...
