Abstract. Nowadays, a very active research area is the 3D cadastre concept. In relation, 3D Cadastre is an essential component used in a land management system which is to manage and represent layered rights digitally, restrictions, responsibilities (legal models), buildings, public services and corresponding physical models (above or below the floor surface in 3D). The 3D Cadastre has a lot of capable of collecting, storing, organising, querying, analysing and visualising very intricate details within specific standards for all over the worlds. Besides, now in Turkey, 3D cadastre is to be designing and developing with academic studies. The cadastral concept was developed for the 3D Cadastral in the early 2000s from studies related to the world countries. 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 cadastre 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. The 3D cadastre scope should be defined as ideal in legal and institutional systems for all of the cadastral 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 for many countries. Besides land tenure recording system with related 2D cadastral systems also. 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 Turkey, the 3D cadastre scope is still working for an academic site. In this study, the first section comprises of the investigation for 3D cadastral systems. Turkey studies and cadastral systems will be discussed in section 2. The scope and principles of 3D cadastre are discussed for Turkey with section 3. Moreover, the obstacles to the implementation of 3D cadastre and international standards developed within the scope of 3D cadastre are discussed and also data models developed for Turkey cadastral system with related international standards (Land Administration Domain Model, INSPIRE and ISO) in section 4. Also, finally, discussion and results were assessed in this paper.
