Such data archive contains the InSAR ground displacement maps produced by the INGV GeoSAR Laboratory and the InSAR working group. The products are retrieved with standard InSAR processing applied to a single pair of SAR images and consist of raster images (geotiff format).
The archive is organized into 5 folders as follows:
Earthquakes: Here are collected the products related to the coseismic phase of an earthquake. They consist of wrapped interferograms and/or ground displacement maps induced by a seismic event. The products are found in folders named with the name and the date of the seismic event. If a product is retrieved with SAR data from more than one space mission, for example Sentinel-1, TerraSAR-X, Cosmo-SkyMed etc, they are divided in related folders (eg, S1, TSX, CSK). When data along both ascending and descending track are available, there is a furhter splitting into ASC and DSC folders.
Volcanoes: Here are collected the products related to the eruptive phase of a volcano. They consist of wrapped interferograms and/or ground displacement maps induced by a volcanic eruption. The products are organized in folders named with the name and the date of the eruptive event. If a product is retrieved with SAR data from more than one space mission, for example Sentinel-1, TerraSAR-X, Cosmo-SkyMed etc, they are divided in related folders (eg, S1, TSX, CSK). When data along both ascending and descending track are available, there is a furhter splitting into ASC and DSC folders.
Subsidence: Here are collected the products related to subsidence phenomena. They consist of wrapped interferograms and/or ground displacement maps induced by a subsidence phenomenon. The products are organized in folders named with the name and the date of the event. If a product is retrieved with SAR data from more than one space mission, for example Sentinel-1, TerraSAR-X, Cosmo-SkyMed etc, they are divided in related folders (eg, S1, TSX, CSK). When data along both ascending and descending track are available, there is a furhter splitting into ASC and DSC folders.
Landslides: Here are collected the products related to landslides phenomena. They consist of wrapped interferograms and/or ground displacement maps induced by a landslides phenomenon. The products are organized in folders named with the name and the date of the event. If a product is retrieved with SAR data from more than one space mission, for example Sentinel-1, TerraSAR-X, Cosmo-SkyMed etc, they are divided in related folders (eg, S1, TSX, CSK). When data along both ascending and descending track are available, there is a furhter splitting into ASC and DSC folders.
Infrastructures: Here are collected the products related to deformation affecting infrastructures. They consist of wrapped interferograms and/or ground displacement maps affecting an infrastructure. The products are organized in folders named with the name and the date of the event. If a product is retrieved with SAR data from more than one space mission, for example Sentinel-1, TerraSAR-X, Cosmo-SkyMed etc, they are divided in related folders (eg, S1, TSX, CSK). When data along both ascending and descending track are available, there is a furhter splitting into ASC and DSC folders.
All the products are provided with two metadata files (.xml), according to INGV (TS_INGV...) and EPOS (Dts_INGV...) standard, summarazing the main parameters related to the acquisitions and the InSAR processing, such to guarantee the data reproducibility.
