Such data archive contains the InSAR ground displacement time series produced by the INGV GeoSAR Laboratory and the InSAR working group. The products are retrieved with multi-temporal InSAR processing applied to datasets of SAR images and consist of shapefiles.
The archive is organized into 5 folders as follows:
Earthquakes: Here are collected the products related to the interseismic phase of an earthquake. They consist of shapefiles with the following attributes for each point target: Latitude, Longitude, Height, Deformation Rate, Deformation Rate Error, Displacement value for any date. The products are organized in folders named with the name of the Area of Interest. 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 inflation/deflation phase phase of a volcano. They consist of shapefiles with the following attributes for each point target: Latitude, Longitude, Height, Deformation Rate, Deformation Rate Error, Displacement value for any date. The products are organized in folders named with the name of the Area of Interest. 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 natural or anthropogenic subsidence phanomena. They consist of shapefiles with the following attributes for each point target: Latitude, Longitude, Height, Deformation Rate, Deformation Rate Error, Displacement value for any date. The products are organized in folders named with the name of the Area of Interest. 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 phanomena. They consist of shapefiles with the following attributes for each point target: Latitude, Longitude, Height, Deformation Rate, Deformation Rate Error, Displacement value for any date. The products are organized in folders named with the name of the Area of Interest. 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 phenomena affecting infrastructures. They consist of shapefiles with the following attributes for each point target: Latitude, Longitude, Height, Deformation Rate, Deformation Rate Error, Displacement value for any date. The products are organized in folders named with the name of the Area of Interest. 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.
