Abstract
A study on the applicability of the INSAR technique on long time scales is presented. The authors generated a database of 69 ERS-1/ERS-2 interferograms of the Groningen area, in the north of The Netherlands, spanning the years from 1992 to 1996. From this database they tried to extract information on the phase stability of man-made features. For this purpose the differential technique has been applied on the interferometric phase values of high coherence pixels along a road. These resulted to be stable in 90% of the cases at the level of 0.6 cm, even on time scales of more years. Also many isolated man-made features revealed the same phase stability in time.Keywords
