Multi-sensor monitoring of Ciudad Guzman (Mexico) ground subsidence

The study of urban subsidence with multi-temporal SAR interferometry is nowadays a well-consolidated approach. Thanks to this powerful technique, it is possible to detect and to measure ground deformation velocity and time series of displacement with high accuracy. This work focuses the analysis on the subsidence phenomenon that is threating the city of Guzman (Jalisco state, Mexico) by means of multi-temporal SAR interferometry applied to a stack of COSMO-SkyMed data, from 2011 to 2015, and a stack of Sentinel-1 TOPSAR mode images, from 2016 to 2018. The work is intended to carry on the study performed with ENVISAT images covering the time span between 2003 and 2010, allowing the continuous monitoring of the deformation process.
