3 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER 1.RATIONALE AND BACKGROUND Israel is a small and very crowded country, where land available for construction is limited and expensive even at the present.

4 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER Area: sq.km. (not including West Bank and Gaza strip) Inhab./sq.km.95% MILLION INHABITANTS YEARS POPULATION (FACTS AND TREND)

5 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER Government resolution of 1999/144: The Minister of Justice … is to submit proposed guidelines for … more efficient land use, including subterranean space… …a solution for ownership problems, registration of rights and surveying… should be developed also for underground space.

6 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER 2. THE 3DCad R&D PROJECT The main goal: elaboration of regulations and standards regarding a digital, three- dimensional cadastral system, including registration of rights in strata. The main goal: elaboration of regulations and standards regarding a digital, three- dimensional cadastral system, including registration of rights in strata.

7 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER The budget: some 0.8 million US $ - approved by the Treasury. (Professional and management preparations for forming an interdisciplinary R&D staff began in the middle of 2002.) The staff started working on September 1, 2002.

8 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER 3. A SUPPORTING LEGAL REALITY The high court of appeals decided: --an order to expropriate land for public benefit (for the purpose of the Haifa Carmel-Tunnels) - was illegal because (inter alia) of the absence - of exact descriptions and measurements of - property. --there is no legal objection to order a partial - vertical expropriation. -the Land Law should be adjusted in order to comply with the changing needs and the comply with the changing needs and the improvement of technology. improvement of technology.

9 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER 4. THE INTERDISCIPLINARY RESEARCH STAFF STAFF Project Manager - a leading cadastre expert. 3DCad geodesy expert - a candidate for Ph.D. degree at Israel Institute of Technology. GIS expert - well experienced in academy research and education.

10 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER Urban planner and architect - a leading professional in Israel. Well versed in legal aspects of various planning issues. Underground engineering expert - geologist, mining- and civil engineer, well experienced in underground development. A legal (real property) expert - having outstanding knowledge in urban planning laws and commercial practice.

11 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER 5. PROJECT MANAGEMENT R&D TEAM Coordinator: The Project Manager Underground engineering expert Urban planner, architect Lawyer – real property expert Cadastral and GIS- experts Modi'in site surveyor

12 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER 6. THE MAIN TASKS OF THE FIRST PROJECT- SEMESTER - Elaboration of a realistic 3DCad concept. -- Creation of provisional regulations for surveying, mapping, processing and surveying, mapping, processing and managing digital 3DCad data, integrated with managing digital 3DCad data, integrated with National GIS database, including legal, National GIS database, including legal, engineering and planning constraints and/or engineering and planning constraints and/or their necessary changes. their necessary changes.

13 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER - Establishment of an initial 3DCad database frame. - Characterization of an engineering and planning expert system, instructing the user according to the expert system, instructing the user according to the designation, status, etc. of the spatial land property. designation, status, etc. of the spatial land property. - Preparation of specific instructions for practical experiments. experiments.

14 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER 7. THE BASIC CONCEPT - a partial list of the principal points a. Registration of rights in space will be carried out by dividing the three dimensional space belonging to dividing the three dimensional space belonging to the surface parcel, into spatial sub-parcels, above or the surface parcel, into spatial sub-parcels, above or below the surface parcel. below the surface parcel. b. Any above- or underground construction will be bounded by a "spatial envelope" having a will be bounded by a "spatial envelope" having a simplified geometry. simplified geometry.

15 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER The division of space, definitions (1) (Design :Eri Goshen) Above-surface space Sub-surfacespace

16 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER The division proposed (example) (Design: Eri Goshen) 2D scheme 3D scheme

17 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER c. Each spatial sub-parcel belongs to the surface parcel and block, below or above it. parcel and block, below or above it. d. Physical objects which spread out into a number of above- ad/or under-surface space of surface parcels, will be subdivided into a number of spatial sub-parcels defined by existing surface parcels. (The unification of these object parts into one unit will be considered.)

18 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER Carmel Tunnel – under the block no

19 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER Parcels to be (partially) expropriated for public benefit in sub- surface space in block no

20 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER Carmel Tunnel spatial sub-parcels in sub-surface space – under the block no

21 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER The division of space, definitions (2) (Design: Eri Goshen)

22 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER Eri Goshen) : Categories of rights to land is space (Design

23 6203 / / 100 / + / 0 / / 100 / - / 0 / / 100 / - / 1 / 3 Surface parcel Spatial sub-parcel in sub-surface space (not in touch with the surface parcel Spatial sub-parcel in sub-surface space (in touch with the surface parcel) Spatial sub-parcel in above-surface space (in touch with the surface parcel)

24 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER 8. PRACTICAL EXPERIMENTS TO BE COMPLETED COMPLETED Three experiments of practical applications: - the old city of Acre - a new urban center of Modi'in (presently in planning) planning) - the center of Tel-Aviv (an existing modern building complex) complex) These three sites represent three different cadastral realities and a range of various problems.

29 FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER 9. NEAR FUTURE TASKS - The basic, conceptual ideas established will be tested by practical applications tested by practical applications - An extensive juridical investigation and verification of the proposed model and its verification of the proposed model and its application will be carried out application will be carried out - Spatial data management and visualization alternatives will be tested, chosen and applied alternatives will be tested, chosen and applied
