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 2742 measure points, for the observed period from April 1995 to December 2000. 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.

One of the aims of the Hammer project is to provide SAR deformation measurements. For this purpose, the Grid Processing On-Demand (G-POD) service was used to provide SAR deformation maps and associated time series for the test sites of Hammer. The G-POD SBAS-DInSAR service was developed through a collaboration between CNR-IREA and ESA-RSS, and is available from November 2014. The service is provided through a user-friendly web-interface, which allows users to perform the full SBAS-DInSAR chain, from RAW data focusing to displacement time series generation. G-POD can process the ESA’s ERS-1/2 and Envisat ASAR data retrieved throughout the Virtual Archive 4 (http://eo-virtual-archive4.esa.int/ in the framework of Supersite Initiative), and can generate single interferogram and/or a multi-temporal analyses. The G-POD service requires dataset selection over a specific area of interest (AOI) together with parameters and threshold setting (e.g. perpendicular baseline, temporal baseline, coherence threshold).
