The ASAR-Envisat dataset, available through the Virtual Archive 4 of ESA (by the Category-1A project, part of the ESA Geohazard Supersites initiative), was processes by using the G-POD service. The SAR dataset, made of 21 images acquired in ascending orbit (track 301) between April 2005 and October 2010, has been analyzed with the SBAS-DInSAR technique. The ASAR-Envisat satellite acquires images characterized by: - Band acquisition: C Band - Wavelength (cm): 5.6 - Incident angle (°): 23° - Azimuth/ground range resolution (m): ≈ 4/20 - Revisit time (days): 35 - Life status: 2002 – 2010 - Space agency: ESA Regarding the G-POD threshold setting of the SBAS processing, the following parameters were used: - Max Perpendicular Baseline (m): 400 - Max Temporal Baseline (days): 1500 - Ground Pixel Dimension (m): 80 - Coherence Threshold: 0.7 - Area of Interest (AOI): selected AOI close to the test site - REF point: Lat. 44.5838 – Lon. 7.1434 The achieved SBAS measurements are provided in geocoded coordinates (Lat/Lon and UTM WGS84), and are reported in an ASCII file. The SBAS 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]. 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 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 :-) https://geoportal.mountaingenius.org/geoserver/gn/wms/kml?layers=gn:ENVISAT_Grange GLG:KML-2.0-http-get-map View in Google Earth https://geoportal.mountaingenius.org/geoserver/gn/wms OGC:WMS-1.1.1-http-get-map gn:ENVISAT_Grange Show geographic position
