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 کاملMine Subsidence Monitoring Using Multi-source Satellite SAR Images
Ground subsidence due to underground mining has posed a constant threat to the safety of surface infrastructure such as motorways, railways, power lines, and telecommunications cables. Traditional monitoring techniques like using levels, total stations and GPS can only measure on a point-by-point basis and hence are costly and time-consuming. Differential interferometric synthetic aperture rada...
متن کاملMonitoring of Recent Land Subsidence and Ground Fissures in Xian with Sar Interferometry
The City of Xian, China, has been experiencing significant land subsidence and ground fissure activities since 1960s that have brought various severe geohazards including damages to buildings, bridges and other facilities. Monitoring of land subsidence and ground fissure activities can provide useful information for assessing the extent of, and mitigating such geohazards. We study the land subs...
