Geodetic analysis and results

GNSS Station OL01 - Time Series 2017-today

Below are the estimated time series for each GNSS LODI Network site for the time period 1/1/2017 - 31/05/2019. At the moment, the processing started on 12/12/2018 - does not show anomalous elevations of the ground.

DInSAR Analysis - Period 1993-2010

The analysis carried out on ERS/ENVISAT data acquired from ascending and descending orbits does not reveal any significant displacements (greater than 2 - 3 mm/year) in the area of interest.

DInSAR Analysis - Period 2015-today

The interferometric analysis using the SBAS-DInSAR technique was carried out using Sentinel-1 (S-1) data for the area of interest and corresponding to 200 images acquired along ascending orbits and 191 along descending orbits for the period March 2015 - May 2019. With these data, 553 and 528 differential interferograms, respectively, were generated, characterized by perpendicular baseline values of less than 200 m. From these interferograms, maps of the mean ground deformation velocity and corresponding time series of deformation were obtained.
