Ground deformation maps of the Visso and Norcia 2016 earthquakes captured from Sentinel-1 SAR

The dataset contains the Line Of Sight (LOS) deformation maps obtained by applying Differential SAR Interferometry (DinSAR) to Sentinel-1 Interferometric Wide-swath (or TOPSAR) imagery.

Two maps are provided: the first maps is the LOS deformation estimated from ascending data, the second map is the LOS deformation from descending images.

Maps are expressed in metres and are provided in raster geotiff format.

Data have been processed with GAMMA Interferometric processor.

Ascending data details:

SAR pairs are dated 2016/10/27 and 2016/11/02, acquired on relative orbit number 44, by Sentinel-1B and Sentinel-1A, respectively.

The DEM used for removing the topographic phase is the SRTM 1 arc second. The interferogram has been generated by applying a 1x5 multi-look factor in azimuth and range, respectively.

Final product has been geocoded in UTM WGS84 33 Nord projection, with a posting of 20 m.

Descending data details:

SAR pairs are dated 2016/10/26 and 2016/11/01, acquired on relative orbit number 22, by Sentinel-1B and Sentinel-1A, respectively.

The DEM used for removing the topographic phase is the SRTM 1 arc second. The interferogram has been generated by applying a 2x10 multi-look factor in azimuth and range, respectively.

Final product has been geocoded in UTM WGS84 33 Nord projection, with a posting of 40 m.
