Representation of Right, Restriction, and Responsibility (RRR) in the 2D cadastral system falls short due to rapid urbanization causing complex infrastructures. Turkish cadastre, as in many other countries, faces difficulties in the daily recording of property transactions such as sales, donations among others. Therefore, it is highly recommended to represent the RRR in 3D Cadastre. The study elaborates on the current RRR in the cadastral system (2D) in Turkey and is proposing a new integrated data model using international standards as Land Administration Domain Model (LADM) and CityGML v2.0 (City Geography Markup Language). We propose an Application Domain Extension (ADE) that extends the LADM and CityGML data model's integration with the legal and administrative concepts defined in Turkish law for cadastral objects. To show the developed model operability, the data was managed in an open-source PostgreSQL database. This paper provides a detailed overview of the Turkish legal cadastral system with the newly developed integrated LADM and CityGML model providing both visualization and standardization within the scope of 3D cadastre and a proposal for its physical realization based on international standards.
