2 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

3 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

4 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

5 PRELIMINARY REMARKS The awareness that existing buildings could be not registered in the Cadastral Databases An area to be investigated of about 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

6 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

7 PHASE I Automatic photo-identification process of the existing buildings not present in the cadastral maps Digital ortho-photo with ground solution 50 cm Pag. 7

8 PHASE I Automatic photo-identification process of the existing buildings not present in the cadastral maps Digital Cadastral cartography in vector format Buildings registered on cadastral maps Pag. 8

9 PHASE I Automatic photo-identification process of the existing buildings not present in the cadastral maps Digital Surface Model (DSM) DSM Pag. 9

10 PHASE I Automatic photo-identification process of the existing buildings not present in the cadastral maps Objects being on the ground (Difference by DSM and DTM) DTM DSM Pag. 10

11 PHASE I Automatic photo-identification process of the existing buildings not present in the cadastral maps Discriminating vegetation (through infrared images) Vegetation Buildings Pag. 11

12 PHASE I Automatic photo-identification process of the existing buildings not present in the cadastral maps Automatic set up of the object centroid from the DSM Pag. 12

13 PHASE I Automatic photo-identification process of the existing buildings not present in the cadastral maps Centroid removal for buildings registered on cadastral maps Hidden (unregistered) buildings centroid Pag. 13

14 PHASE I Automatic photo-identification process of the existing buildings not present in the cadastral maps Hidden buildings centroid on vector cadastral maps Identification of the cadastral parcels (and related owners) on which unregistered buildings exist Pag. 14

15 PHASE I Matching of the automatic photo-identification results with the contents of the alphanumeric cadastral DBs Automatic Photo-identification Process Matching Alphanumeric Cadastral DBs DB of photo-identified parcels not present on cadastral maps Selected parcels to be checked by AdT Pag. 15

16 PHASE I Owners involvement through the publication of the lists of the identified parcels Cadastral parcels on which unregistered buildings exist Official Gazette of the Italian Republic Information through Municipalities Agenzia del Territorio Web-site Pag. 16

17 PHASE II The human check parcel by parcel Total selected parcels coming from the automatic extraction phase HIDDEN BUILDINGS HUMAN CHECK (STILL IN PROGRESS) HIDDEN BUILDINGS to be registered (EXPECTED) Registration requested to the owners Buildings not interesting for Cadastre Errors in the automatic extraction Licensed Professionals Pag. 17

18 PHASE II Tools implemented for the parcel by parcel check GEO-REFERRED INFORMATION (parcel by parcel and aggregated) 3D IMAGES (when available) Pag. 18

19 PHASE II Tools implemented for the parcel by parcel check LIST OF PARCELS TO BE PROCESSED AND RELATED WORK PROGRESS LIST OF DOCUMENTS RELATED TO EACH PROCESSED PARCEL (technical updating documents submitted, communications, etc ) DIRECT LINK TO THE PERTINENT CADASTRAL MAP A COMPLETE MONITORING SYSTEM Pag. 19

20 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

21 PROJECT RESULTS Number of cadastral parcels on which unregistered buildings exist, processed year by year Updating Hidden Buildings Full Registration Process Year Year Year Year parcels parcels Ongoing activity (PHASE II or III in progress) Activity to be started (PHASE I completed) Year Year Activity closed (PHASE III completed) TOTAL The results Hidden Hidden Buildings Buildings registered registered millions Related Related cadastral cadastral income* income* * Reference value for several real estate taxes Pag. 21

22 PROJECT RESULTS Typology of Buildings registered and related cadastral income buildings registered cadastral income DWELLINGS STOREHOUSES GARAGES BUILDINGS UNDER CONSTRUCTION OTHER Pag. 22

23 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 WORK HOURS Year 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
