Abstract :
From a series of interferograms spanning 3 and 1/2 years, a sample of features has been extracted which appear to have constantly high coherence for the whole time interval. These features, mainly of anthropogenic nature, have then been studied in order to assess whether they can be used for long time monitoring of slow deformation processes in almost completely decorrelated areas. For this purpose, both the coherence and the phase stability of the features have been checked along the time series
