  • RATIONALE AND BACKGROUND

  • Israel is a small and very crowdedcountry, where land available for construction is limited and expensive even at the present.

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.

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.

FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER


Slide7 l.jpg

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.

  • 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 objectionto order a partial

  • vertical expropriation.

  • -the Land Law should be adjusted in order to

  • comply with the changing needs and the

  • improvement of technology.

  • 6. THE MAIN TASKS OF THE FIRST PROJECT-SEMESTER

  • - Elaboration of a realistic 3DCad concept.

  • - Creation of provisional regulations for

  • surveying, mapping, processing and

  • managing digital 3DCad data, integrated with

  • National GIS database, including legal,

  • engineering and planning constraints and/or

  • their necessary changes.

FIG WORKING WEEK 2003 IN PARIS –– FORRAI - KIRSCHNER


Slide13 l.jpg

- Establishment of an initial 3DCad database frame.

- Characterization of an engineering and planning

expert system, instructing the user according to the

designation, status, etc. of the spatial land property.

- Preparation of specific instructions for practical

experiments.

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

the surface parcel, into spatial sub-parcels, above or

below the surface parcel.

b. Any above- or underground construction

will be bounded by a "spatial envelope" having a

simplified geometry.

c. Each spatial sub-parcel belongs to the surface

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.)

8. PRACTICAL EXPERIMENTS TO BE surface parcel)

COMPLETED

Three experiments of practical applications:

- the old city of Acre

- a new urban center of Modi'in (presently in

planning)

- the center of Tel-Aviv (an existingmodernbuilding

complex)

These three sites represent threedifferent cadastral realities and a range of various problems.

9. NEAR FUTURE TASKS By courtesy of Mr Ronen Grinstein.

- The basic, conceptual ideas established will be

tested by practical applications

- An extensive juridical investigation and

verification of the proposed model and its

application will be carried out

- Spatial data management and visualization

alternatives will be tested, chosen and applied
