SAR interferometry confirms the present land stability of Venice

The city of Venice Is very vulnerable to loss in land elevation as a result of subsidence and eustacy because of its small elevation above sea level. The alarm of the scientific community related to this persistent problem is increasing because of the forecasts of sea level rise caused by global warming. In order to evaluate the present relative settlement of Venice, a study has been performed by combining high precision levelling surveys and SAR interferometry. The analysis points out at an unprecedented detail the present ground stability of the city.
