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 کاملLand Subsidence Monitoring in Australia and China using Satellite Interferometry
Continued excessive extraction of groundwater may lead to significant land subsidence, which causes economic loss. The aim of this research is to investigate ground subsidence in several Australian capital cities using the Persistent Scatterer Interferometry approach. Such studies may help improve our understanding of the deformation of terrain and built structures, and evaluate the effectivene...
متن کاملInsar and Polinsar for Land Subsidence Monitoring User Perspective
In this paper the selected interferometric studies of subsidence caused by underground mining are discussed. Despite the common limitations the traditional single-polarization InSAR technique is already proved its high potential in this application. Today, the determination of the areas of affected by terrain deformation risks becomes one of the most promising applications for operational use o...
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...
