19 Sinkholes in karst areas may cause subsidence damage in transportation infrastructures, 20 demolition of buildings and even the loss of human lives when they occur in a 21 catastrophic way. Differential Interferometry (DInSAR) is a promising technology for 22 detecting and characterizing sinkholes, as well as for reducing the associated risk when 23 combined with other sources of data such a...

This paper presents airborne DInSAR results using a stack of 14 images, acquired by the E-SAR system of DLR during a time span of only three hours and fifteen minutes. An advanced differential technique is used in order to retrieve the error in the digital elevation model (DEM) and the temporal evolution of the deformation for every coherent pixel in the image. Furthermore, some modifications i...

Mining exploitation leads to slow or rapid ground subsidence resulting from deformation until the collapse of underground post-mining voids following excavation activities. Satellite SAR interferometry capabilities for evaluation movements allows monitoring intensive surface mine and can provide new knowledge about risks in mining industry. This work integrates both conventional advanced Differ...

Line of Sight (LOS) deformation based on Differential Interferometric Synthetic Aperture Radar (DInSAR) techniques cannot be used in traditional probability integration method (PIM) parameter inversion. To improve the accuracy inversion, a model 3D was proposed. The simulates using PIM directly. inverse Sum Squared Errors (SSE) results and measured as fitting function within GA. Reliable parame...

Within the framework of a research project carried out in collaboration with the Department of Geography of the Vrije Universiteit Brussel (VUB), we have studied the contribution of Synthetic Aperture Radar (SAR) phasimetry in the field of glaciology. The main objective of this research was to extract surface velocity fields for the Shirase glacier, a fast-flowing continental ice stream in Drau...

This paper addresses a question often asked by industry: can radar interferometry (or InSAR or IFSAR) deliver services on a commercial and/or operational basis? To answer this question two systems based on InSAR for digital elevation model (DEM) generation are considered. One commercial system is the GeoSAR Xand P-band radar aerial mapping system from EarthData. The X-band can deliver digital s...

Además, se presen...

Regional changes in the flow velocity of Antarctic glaciers can affect ice sheet mass balance and formation surface crevasses. The anomaly a glacier be detected using Double-Differential Interferometric Synthetic Aperture Radar (DDInSAR) technique that removes constant displacement two Differential SAR (DInSAR) images at different times shows only temporally variable displacement. In this study...

Surface subsidence caused by coal mining has become an important factor that affects and restricts the sustainable development of districts. It is necessary to use appropriate methods for effective monitoring. hard monitor large gradient ground deformations with a high accuracy using differential interferometric synthetic aperture radar (DInSAR) technology. Unmanned aerial vehicle (UAV) photogr...
