  • A big improvement in comparison to the previous IFFI inventory was made also regarding the data-store infrastructure. All data are now stored in a geographic PostgreSQL/PostGIS database, also containing the whole geological information system of Arpa. Adopting a single geo-database that contain all geo-thematic data allow to reach an higher level of integration with all landslide description ancillary data contained into the Arpa information system such as: monitoring data, borehole log, historical bibliographic data, etc. All the related information can now be simply linked together by the user and become automatically available from one component of information system to another. Moreover, is it possible to automatically intersect the most significant data with landslide geometry: as an example a simple statistic about PSInSAR™ data, with n° of PS that falls into the landslide, their average, min and max velocity and other basic information was calculated immediately at the end of geometry digitalization. The same thing was made with other data as: environmental or land use regulations, land cover and the nearest meteorological station in order to have a fast landslide characterization, or with element at risk as anthropic infrastructure, dam etc., so that basic statistics were disposable just in real time.
  • The inventory defining three levels of landslide knowledge, depending on the available information. The first level defines a basic landslide classification (shape, location, state of activity and type); the second level includes more detailed data from field surveys; the third includes data available from the pre-existing detailed studies.
  • In the framework of an European Project (Alcotra Risknat), in 2010, we covered an Alpine area of about 13'000 km2 using data sets from Canadian RADARSAT satellite, covering the time span from 2002 to 2009. The survey was made using a newly patented processing algorithm (the SqueeSAR™) by the Politecnico of Milano and identified more than 2 millions PS. SqueeSAR™ (Ferretti et al, 2011) is a second generation PSInSAR™ analysis: exploiting both ‘point wise’ PS and ‘spatially distributed scatterers’ (DS). The new algorithm provides information in low-reflectivity homogeneous areas by identifying DS–previously unidentified with PSInSAR™.
  • Il sito in esame è monitorato mediate inclinometri fissi e piezometri dall'inizio degli anni '80. Nel tempo il sistema di monitoraggio è stato in parte integrato con nuovi strumenti, sia per sostituire vecchi strumenti su cui non era più possibile effettuare letture, sia per raggiungere profondità maggiori. Attualmente la strumentazione attiva, gestita da Arpa Piemonte è costituita da 7 inclinomenti attivi, 1 inclinometro fisso e 3 piezometri per il Sito di Grange Sises, e 3 inclinometri, 2 piezometri ed 1 inclinometro fisso per quello di Bessen Haut.

    • 2. Arpa PiemonteL. Lanteri Second World Landslide Forum - Rome 3-7 october 2011 The integration between satellite data and conventional monitoring system in order to update the Arpa Piemonte landslide inventory Arpa Piemonte is in charge of the maintenance of the framework about the hydrogeological instability of the Piemonte region. Introduction Starting from the end of '70, the Geological Survey of Piemonte Region collects information concerning flooding, landslides, geomechanical characteristics of earths and rocks and is in charge of the management and the development of the regional landslide-monitoring system. In 2002 all this topics was moved into the ARPA Piemonte (Regional Agency for Environmental Protection) where the Thematic Department “Geologia e Dissesto” continues to maintain this valuable resource up to date. A first 1:100,000 regional landslide mapping was carried out for the entire regional territory in the first part of '80s. 1:100,000 regional landslide map
    • 3. Arpa PiemonteL. Lanteri World Landslide Forum - Rome 3-7 october 2011 The integration between satellite data and conventional monitoring system in order to update the Arpa Piemonte landslide inventory From 2000 to 2005 the IFFI project (The Italian landslide Inventory) contributes to increase the level of knowledge and allow to product a national homogeneous landslide information system. In 2005, on the bases of IFFI results, about 470.000 single phenomena have been identified and analysed in the whole Italy. Introduction 35,023 landslides in Piedmont Region
    • 4. Arpa PiemonteL. Lanteri World Landslide Forum - Rome 3-7 october 2011 The integration between satellite data and conventional monitoring system in order to update the Arpa Piemonte landslide inventory SIFRAP (The landslide inventory of Piedmont) was born in 2005 as an evolution of the IFFI project. Arpa Piemonte, continues to feed and to develop the inventory by:  Database evolution;  Developing of new tools for analisys and manage data;  Inventory updating;  Data spreading; SIFRAP – Landslide inventory All this activities are achieved during the istitutional work and by the European INTERREG Project. One of the main goal of working package B2 of the ALCOTRA European Project RISKNAT is focused to improve the knowledge of the SIFRAP, in particular on the more serious phenomena where detailed examination is needed.
