Grange Orgiera SAR ground deformation time series from Envisat ASAR satellite images
The SAR ground deformation time series relevant to Grange Orgiera test site 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 provided 41555 measure points, for the observed period from April 2005 to October 2010, relative to the area of interest.
The archive provide for each SBAS targets:
- 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 SAR results, relevant to the entire frame (normally around 100x100 km), have an accuracy of 1 mm/yr concerning the 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 displacements over time.

- Purpose
- Provide ASAR-Envisat deformation maps and associated time series for the Grange Orgiera test site. Carry out a critical analysis of the possibility of using space-borne DInSAR techniques to obtain multi-decadal time series of ground deformations for landslide areas, to be correlated with meteorological and climatic variables.

- You can customize the template to suit your needs. You can add and remove fields and fill out default information (e.g. contact details). Fields you can not change in the default view may be accessible in the more comprehensive (and more complex) advanced view. You can even use the XML editor to create custom structures, but they have to be validated by the system, so know what you do :-)
