Inventory of Franosi phenomena in Italy (IFFI)

The dataset is made up of the shp-files of landslides recorded in Umbria by the IFFI inventory (Inventory of Franchise Phenomena in Italy), the first territorial information system on a national scale, realised by ISPRA and the Regions and Autonomous Provinces, which provides a complete and up-to-date picture of the distribution of landslides in Italy, according to standardised procedures. The inventory recorded in Umbria 34,545 landslides that affect an area of about 651 km², equal to 8.9 % of the hilly-mountain territory. The data are updated to 2017 for some landslides in the municipalities of Acquasparta, Alviano, Castel Ritaldi, Città della Pieve, Città di Castello, Collazzone, Deruta, Ficulle, Foligno, Fratta Todina, Gualdo Tadino, Gubbio, Lisciano Niccone, Lugnano in Teverina, Magione, Monteleone d’Orvieto, Narni, Orvieto, Parrano, S. Anatolia di Narco, Scheggino, Stroncone and Umbertide. The IFFI inventory was approved as the main reference document for the instability of the Umbria Region with Decree No 384 of 29 April 2013. **** The data available, relating to the landslides “IFFI” of the Umbrian territory, are composed of three different shp-files: one contains the landslide polygons (types of movement 0 to 8), another the landslide areal polygons (moving typologies 9 to 11) and another includes the identification points of all polygons (PIFF); landslides with an extension of less than one hectare shall be represented solely by the PIFF. *** The attached legend explains the meaning of the identification numbers of the type of landslide. From the shp-files it is possible to know the extent of the landslide and its type, identified with numbers from 0 to 11, while for further alphanumeric data refer to the Project IFFI — Cartography on-line, of the Higher Institute for Environmental Protection and Research (ISPRA), at the following address http://193.206.192.136/cartanetiffi, on the website www.isprambiente.gov.it
