Abstract:
The differential SAR interferometry has been applied to study the
displacement field in an urban area. A set of 6 ERS1/2 SAR images has
been used to detect, map and quantify the subsidence occurring in the
city of Prato near Florence (Italy). Four areas affected by strong
subsidence during the period 1993-2000 have been spotted within the
city. The analysis of three interferograms processed from images taken
two years apart shows that the deformation rate is constant, with a
maximum value of about 8.3 cm.yr(-1).
