Relative to the Ivancich test site several space-borne data were available. In particular, the SAR data were published in: Calò et al. (2014) Enhanced landslide investigations through advanced DInSAR techniques: The Ivancich case study, Assisi, Italy. Remote Sensing of Environment, 142: 69-82. This dataset is a courtesy of Ing. Maceo Giovanni Angeli (IRPI-CNR) and Dr. Geol. Fabrizio Pontoni (private consultant).

This archive collects ERS-1/2 and Envisat ASAR satellites data for the observed period from April 1992 to November 2010.

The ERS-1/2 and Envisat ASAR satellites acquire images characterized by:

- Band acquisition: C Band

- Wavelength (cm): 5.6

- Resolution azimuth/range (m): ≈ 6/24

- Revisit time (days): 35

- Incident angle (°): 23

- Life status:1992-2001 (ERS-1/2) and 2003-2010 (Envisat ASAR)

- Space agency: ESA

The images used, processed by SBAS DInSAR technique at full-resolution scale (5 m x 20 m), include 130 (91 ERS-1/2 and 39 Envisat ASAR) images spanning from April 1992 to November 2010 in descending orbit, of the territory of Central Umbria.

The SAR data reports 124919 SBAS targets in shapefile format provided in SBAS-InSAR geocoded coordinates (Lat./Lon. and UTM WGS84).
