The 3D cadastre is a tool
used in a land management system to digitally manage and represent layered
rights, restrictions, responsibilities (legal models), buildings, public
services and corresponding physical models (above or below the floor surface in
3D). A 3D Cadastre is capable of collecting, storing, organising, querying,
analysing and visualising very intricate details within specific standards
(Aien, 2013).
The cadastral concept was
developed for the 3D Cadastral in the early 2000s. The first workshop was held
in 2001; the second workshop was held in 2011 and 2012 in the third.
Temporarily, many theoretical and practical developments have emerged in these
workshops. However, no 3D cadastre is currently being performed anywhere in the
world (Oosterom et al., 2011). There are several reasons why successful
implementation of 3D cadasters is legal, institutional and technical. These
reasons can be listed as the necessary legal documents, missing data models,
lack of technology and data format deficiencies (Aien, 2013).
The 3D cadastre scope should
be defined as ideal in legal and institutional systems. While waiting for these
formalities, the development of a data model for 3D cadastre is a useful method
to clarify the scope of 3D cadastre. A 3D cadastral data model is the most
important for the introduction of standards (INSPIRE, OGC, LADM) and a common
language within the user communities of the Land Administration. In this
context, some countries (Netherlands, Australia) have developed cadastral data
models (ePlan, Legal Property Object Model, LADM, 3D Cadastral Data Model) to
improve their cadastral systems. Although cadastral data models differ between
countries, 2D is based on the basic building block of a land parcel. The
existing cadastral data models were developed based on the definition of a 2D
land parcel (Kalantari et al., 2008). In line with the developed models,
Netherlands, Australia, Croatia and Israel improved their existing cadastral
systems and carried out studies in the scope of 3D cadastre.
In the first section, the
scope and principles of 3D cadastre are discussed. And then obstacles to the
implementation of 3D cadastre and international standards developed within the
scope of 3D cadastre are discussed. The cadastral data models developed within
the scope of 3D cadastre were analysed in Section 2. TUCBS (Turkey National
Geographical Information System) project, which was established in Turkey by
comparing these data models, was discussed. The Netherlands, Australia,
Croatia, Israel and Turkey were compared to studies they have done to improve
their cadastral system in Chapter 3. TUCBS project was evaluated in the
framework of LADM (Land Administration Domain Model) in section 4. And finally,
discussion and results were assessed.
