PS-InSAR project
The PS-InSAR project, released in 2019, allows the use and publication of interferometric data by the web.
The portal offers the opportunity to visualize the ground deformation historical series elaborated by the PSInSAR data processing in a single environment where they are integrated with the geological data, the information deriving from the applied geology and the data of the regional landslide and flood inventory.
The access to information is restricted and free. It can be made place in 3 different ways:
Partout version
Partout version – limited access for public bodies of the Aosta Valley Autonomous Region (PS-INSAR is activated automatically)
EnterDescription:
Thanks to an agreement between the Valle d'Aosta Region and the Department of Earth Sciences of the University of Florence (DST-UNIFI), the Regional Geological Survey (Geological Activities of the Planning, Water Resources and Territory Department of the Autonomous Region of Valle d'Aosta) receives every 15 days PS InSAR data, resulting from the continuous monitoring of the ground deformations of the Valle d'Aosta territory by the InSAR data detected by the SENTINEL-1 constellation sensors.
The project activity plan:
- The development of web interfaces for the use of interferometry data via the web.
- The publication on the web of a map service based on a database containing the historical series of interferometric data.
- The implementation of computer tools for consulting and interpreting the interferometric data integrated into the Geology portal.
- The data shall be displayed using a specific colour scale classified according to the annual deformation rate (expressed in mm/year).
- The development of a module that can be integrated and used in QGIS, for the continuous updating of the dataset as new data become available.
Spatial Coverage: Regional territory (3262 sq. km)
Access: Free and restricted
It is possible to submit to the Geological Survey (Attività geologiche) of the Department of Finance, Innovation, Public Works and Land Management, (Amérique, 33 - 11020 QUART - AO) a formal request to access the restricted data (AO). The metadata are made available, and the use of metadata can only take place for "public" activities and, in any case, the Regional Administration owns the right not to accept the request.
In any case the Regional Administration cannot be held responsible for any interpretation that will be made, using the PsInSARTM and SqueeSARTM data.
