Upper Tena Valley SAR ground deformation time series from Envisat ASAR satellite images (ascending orbit)

The SAR ground deformation time series relevant to Upper Tena Valley include deformation data obtained from the ERS-1/2 satellite acquisition (produced by Altamira and available by the Framework Agreement between NextData Project and Terrafirma, signed in July 2014), and elaborated by PSInSAR technique. In particular, the analysis provided 926 measure points, for an observed period from October 2002 to July 2007.

The analysis provided for each PS:

- CODE

- East and North UTM WGS84 coordinates (m);

- Azimuth and Range coordinates [Azimuth/Range.];

- Height (m);

- Deformation Velocity (cm/yr.) [VEL];

- Temporal interferometric coherence [COHERENCE];

- Standard deviation [STDDEV];

- Unwrapping group;

- Deformation Data (mm), related to the date of the exploited SAR images.

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 Upper Tena Valley 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.

Supplemental Information
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 :-)
