The article discusses the development of 3D cadastre in Turkey, which is a way to digitally manage land rights and buildings in three dimensions. The researchers highlight the importance of creating a data model for 3D cadastre to ensure consistency and standardization. Countries like Netherlands, Australia, Croatia, and Israel have already made progress in improving their cadastral systems with 3D technology. The main goal is to establish a legal and institutional framework for 3D cadastre, addressing challenges like missing data models and technology limitations.
