Groundwater dynamics caused by extraction and recharge are one of the primary causes subsidence in urban environment. Lahore is second largest metropolitan city Pakistan. The rapid expansion this area due to high population density has increased demand for groundwater meet commercial household needs. Land inadequate long been a concern Lahore. This paper aims present persistent scatterer interf...

Abstract. Persistent Scatterer Interferometry (PSInSAR) exploits a time series of Synthetic Aperture Radar (SAR) images to estimate the mean velocity with which surface earth is deforming. However, most PSInSAR algorithms velocities using linear regression model. Since some deformation phenomena can exhibit more complex behavior over time, model leads potentially wrong estimations for velocity....

We present measurements of morphological features in a thick turbid sample using light-scattering spectroscopy (LSS) and Fourier-domain low-coherence interferometry (fLCI) by processing with the dual-window (DW) method. A parallel frequency domain optical coherence tomography (OCT) system with a white-light source is used to image a two-layer phantom containing polystyrene beads of diameters 4....

Geoinformation derived from Earth observation (EO) plays a key role for detecting, analyzing and monitoring landslides to assist hazard and risk analysis. Within the framework of the EC-GMES-FP7 project SAFER (Services and Applications For Emergency Response) a semi-automated object-based approach for landslide detection and classification has been developed. The method was applied to a case st...

1 — Much interest is growing in advanced interferometric SAR methods for full 3D imaging. Multibaseline SAR tomographic elevation beam forming, i.e. spatial spectral estimation, is a promising technique in this framework. Recently, this concept has been integrated with the differential interferometry concept, producing the advanced differential tomography processing mode which produces ‘space-t...

Persistent Scatterer Interferometry (PSI) is one of the most powerful tools for identifying and monitoring areas exposed to surface deformations such as landslides or subsidence. In this work, we propose a new method that named CAPS (Correlation Analysis on Scatterers), extend capability PSI in recognizing characterising influenced by complex ground differential motions. must be applied both as...

Land subsidence is a major concern in vastly growing metropolitans worldwide. The most serious risks this scenario are linked to groundwater extraction and urban development. Pakistan’s fourth-largest city, Rawalpindi, its twin Islamabad, located at the northern edge of Potwar Plateau, witnessing extensive expansion. Groundwater (tube-wells) residents’ primary daily water supply these metropoli...
