THE ITALIAN e-cadastre e MANAGING BODY AGENZIA DEL TERRITORIO IS A NON - PROFIT PUBLIC BODY RESPONSIBLE IN ITALY FOR THE CADASTRE, PUBLIC REGISTERS OF REAL ESTATE RIGHTS AND REAL ESTATE MARKET OBSERVATORY THE AGENCY, AUTONOMOUS FROM AN ORGANISATIONAL, ADMINISTRATIVE AND D FINANCIAL POINT OF VIEW, ACTS UNDER THE SUPERVISION OF THE MINISTRY OF ECONOMY AND FINANCE Pag. 2
THE ADDED VALUE COMING FROM THE INTEGRATION Agenzia del Territorio (AdT), as managing body of the nationwide real properties register (Cadastre), is engaged in several initiatives aiming at reducing tax evasion and avoidance in the real estate field. THANKS TO THE FULL COMPUTERIZATION OF THE ITALIAN CADASTRAL SYSTEM AND THE USE OF ADVANCED TECHNOLOGICAL PLATFORMS, IT WAS POSSIBLE TO IMPLEMENT A VERY INNOVATIVE PROJECT, BASED ON THE INTEGRATION OF THE AdT DATABASES WITH EXTERNAL ONES AND AIMING AT IDENTIFYING BUILDINGS THAT, ALTHOUGH EXISTING, ARE UNKNOWN TO THE CADASTRE Pag. 3
THE HIDDEN BUILDINGS PROJECT Human Check parcel by parcel (in progress) PRELIMINARY REMARKS PHASE I PHASE II PHASE III RESULTS Automatic Massive Survey (completed) Registration of the Hidden Buildings (in progress) Pag. 4
PRELIMINARY REMARKS The awareness that existing buildings could be not registered in the Cadastral Databases An area to be investigated of about 270.000 square kilometres The awareness that only making use of the most advanced technologies it was possible to investigate the whole national territory, in an acceptable time. Pag. 5
PHASE I : THE MASSIVE SURVEY THE INNOVATIVE OPERATING APPROACH A MASSIVE EXTRACTION OF BUILDINGS UNKNOWN TO THE CADASTRE THROUGH THE PHOTO-INTERPRETATION OF HIGH RESOLUTION AERIAL IMAGES ANALYTICAL PROCEDURE Automatic methodology including the analysis and processing of: Digital Terrain Model (DTM) and Digital Surface Model (DSM); Infrared images; Vectorial cadastral cartography; Preliminary Human check of the inconsistencies through: Colour high resolution ortho-photos (50 cm) Pag. 6

PHASE III Cadastral registration of hidden buildings PARCELS DB DB coming from from PHASE I I Owners involvement parcel by by parcel Human Check PHASE II II Communication from the the owner about errors in in the the parcel identification process Notice of field survey by AdT Communication 7 months after the publication HIDDEN BUILDINGS REGISTRATION PROCEDURE Cadastral survey and registration ex officio Submission of cadastral updating documents END of of the the ACTIVITY Pag. 20

RESOURCES TAKEN UP IT (data processing tools) The costs related to the implementation of the IT data processing g tools are not directly appraisable because part of them was already available to the AdT for its institutional ordinary work and the remaining part was developed directly with the support of the AdT technological partner NON CADASTRAL GEO-DBs The financial resources related to the massive photo-interpretation process, carried out through the integration of cadastral DBs with external ones, were reduced putting in action synergies with other Public Bodies interested, for different purposes, in the same outputs Year 2007 NEGLIGIBLE (Phase I Automatic photo-identification process) HUMAN RESOURCES Year 2008 245.000 WORK HOURS Year 2009 240.000 WORK HOURS ASSUMING FOR THE FUTURE THE SAME AdT HUMAN RESOURCES ENGAGEMENT WE EXPECT THAT ALL THE ACTIVITY RELATED TO THIS PROJECT WILL CLOSE IN ABOUT THREE YEARS (considering the owners participation in the process constant) Pag. 23
