Persistent Scatterer Interferometry (PSI) is a remote sensing technique used
to measure and monitor land deformation from a stack of interferometric SAR
images. The main products that can be derived using the PSI technique are
the deformation maps and the time series of deformation. In this paper, an
approach to apply the PSI technique to a stack of Sentinel-1 images is
described. Moreover, the problems encountered during the processing are
detailed and an explanation of how they were dealt with is provided.
Finally, Sentinel-1 deformation maps and time series obtained over the
metropolitan area of Mexico DF are shown.
