Applicazioni in ambito urbano di interferometria differenziale

This paper describes two examples of deformation monitoring based on two complementary differential interferometric SAR (Synthetic Aperture Radar) techniques. The first application concerns a thin and elongated infrastructure, the main dike of the Port of Barcelona, while the second one regards a group of buildings in an urban area. In the first application, the dike was measured by using a Persistent Scatterers technique called Stable Point Network and implemented by Altamira Information. This application illustrates the high quality of the deformation estimated derived by this technique. The second application, which was measured by using a classical DInSAR approach and a small set of interferograms, shows the effectiveness of a simple analysis in an operational context.
