Land Subsidence Monitoring with Differential SAR Interferometry
The potential of differential SAR interferometry for land subsidence monitoring is reported on. The principle of the technique and the approach to be used on a specific case are first presented. Then significant results using SAR data from the ERS satellites for various sites in Germany, Mexico, and Italy, representing fast (mlyear) to slow (mmlyear) deformation velocities, are discussed. The S...
متن کاملLand Subsidence Measurement with Sar Interferometric Data
The paper focuses on the measurement of land subsidence and, more generally, of land deformation phenomena using the differential interferometric SAR (Synthetic Aperture Radar) technique (DInSAR). The paper begins with a concise description of the properties of the differential interferometric phase, which represents the information source for the estimation of the terrain deformation phenomena...
متن کاملDifferential Sar Interferometry for Land Subsidence Monitoring: Methodology and Examples
In recent years significant progress was achieved in SAR interferometry. In this paper we report on the potential of differential SAR interferometry to map land subsidence. After a presentation of the methodology the focus will be on feasibility demonstration and accuracy assessment. The theoretical considerations are verified with the selected cases Ruhrgebiet, Mexico City, Bologna, and Eugane...
متن کاملDetecting Land Subsidence in Shanghai by PS-Networking SAR Interferometry
Existing studies have shown that satellite synthetic aperture radar (SAR) interferometry has two apparent drawbacks, i.e., temporal decorrelation and atmospheric contamination, in the application of deformation mapping. It is however possible to improve deformation analysis by tracking some natural or man-made objects with steady radar reflectivity, i.e., permanent scatterers (PS), in the frame...
متن کاملEvaluation of Sentinel-1 Interferometric SAR Coherence efficiency for Land Cover Mapping
In this study, the capabilities of Interferometric Synthetic Aperture Radar (InSAR) time series data and machine learning have been evaluated for land cover mapping in Iran. In this way, a time series of Sentinel-1 SAR data (including 16 SLC images with approximately 24 days time interval) from 2018 to 2020 were used for a region of Ahvaz County located in Khuzestan province. Using InSAR proces...
