book coordinated by Olivier Cavalié and Emmanuel TrouvéLangues : Anglais (eng) Résumé : (auteur) Image matching is a well-known problem in the Earth sciences and features in two main applications: the computation of three dimension (3D) geometry from images acquired from different viewpoints and the computation of surface deformations from images acquired from similar points of view. The most common image-matching approach is the so-called vignette or template matching. The ideal sensor simulates a single-line pushbroom sensor, free from optical distortions and from the jitter artifacts caused by high-frequency attitude changes. Until recently, frame cameras were more common in terrestrial and airborne applications, whereas pushbroom scanners were a standard in space borne imaging. Currently, the energetic approach is the most common way to solve the matching problem, both in academic and commercial software solutions. Sensor orientation in 3D space is carried out in two steps by applying the so-called intrinsic and extrinsic calibration parameters.

book coordinated by Olivier Cavalié and Emmanuel TrouvéLangues : Anglais (eng) Résumé : (auteur) This chapter presents the application of spaceborne synthetic aperture radar (SAR) interferometric techniques to ground surface deformation resulting from human activity. Subsurface anthropogenic activity can also amplify natural subsidence and can even trigger significant earthquakes. Interferometric SAR (InSAR), as a space-based geodetic tool, thus provides interesting imaging capability for the mapping and monitoring of land motion in response to anthropogenic activities. InSAR can be applied during all phases of tunneling projects: before, to identify pre-existing ground movements; during the work; and after the completion of the work for residual deformation monitoring. InSAR also plays a growing role in evaluating water-management practices and in implementing appropriate water-management strategies that may include subsidence mitigation. Spaceborne SAR interferometry can contribute to such monitoring by complementing and partially replacing ground-based measurements. Fluid extraction and cavity excavation are the main anthropogenic sources of subsidence.
