Differential 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 کاملLand 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 کاملA Procedure to Map Subsidence at the Regional Scale Using the Persistent Scatterer Interferometry (PSI) Technique
In this paper, we present a procedure to map subsidence at the regional scale by means of persistent scatterer interferometry (PSI). Subsidence analysis is usually restricted to plain areas and where the presence of this phenomenon is already known. The proposed procedure allows a fast identification of subsidences in large and hilly-mountainous areas. The test area is the Tuscany region, in Ce...
متن کاملEvaluation of land subsidence in Kashmar-Bardaskan plain, NE Iran
The development of agriculture and industry and the increase of population in countries with arid to semi-arid climates have led to more harvesting of groundwater resources and as a result land subsidence in different parts of the worlds. Decades of groundwater overexploitation in the Kashmar-Bardaskan plain in the north-east of Iran has resulted substantial land subsidence in this plain. The p...
