Persistent Scatterer Interferometry analysis of Sentinel-1 radar images was carried out to assess the land subsidence phenomenon in the city of Vienna, Austria. The analysed dataset consisted of sixty Sentinel-1A Interferometric Wide images of January 2018 – December 2019, acquired in ascending orbit in vertical transmitting - vertical receiving polarization. In the city of Vienna do not occur major anomalies of land subsidence or uplift. However, there were detected few small zones with negative vertical displacement rates of up to -10 mm/year. Land subsidence in the area of the recently constructed Orbi tower detected by the PSI analysis is discussed in more detail. Further monitoring using geological engineering works and geodetic measurements is needed for this area. The study is a contribution on the assessment of subsidence and ground settlement processes in the city of Vienna, by means of satellite radar imagery.
