Sampeyre SAR ground deformation time series from Envisat ASAR satellite images
The SAR ground deformation time series relevant to Sampeyre frame include deformation data obtained from ASAR-Envisat satellite acquisitions (images available in the framework of Category-1A project, part of the ESA Geohazard Supersites initiative), and elaborated by the ESA’s G-POD service with the SBAS technique. In particular, the analysis provided 65535 measure points, for the observed period from April 2005 to October 2010, relative to the entire frame.
The archive provide for each SBAS targets:
- ID: Gr1; Gr2; Gr n
- East and North UTM WGS84 coordinates (m);
- Temporal interferometric coherence [CohT];
- Deformation velocity (cm/year) [Vel];
- Azimuth and Range coordinates [Az/Rg];
- Latitude and Longitude coordinates (deg) [Lat/Lon];
- Topography (m) [RT];
- Deformation Data (cm), related to the date of the exploited SAR images.
The date of the exploited images are expressed as: [year+((month-1)*30+day)/365].
The SBAS results, relevant to the entire frame (normally around 100x100 km), have an accuracy of 1 mm/yr for mean velocity measurements, and 5 mm for the deformation measurements [Casu et al., 2006].
The deformation time series present a monthly temporal sampling, and provide long time series of deformation, allowing to follow the evolution of surface displacement over time.
