The need for more land resulting from population growth, urbanization and industrialization has increased the pressure on land use planning and development. To extend the use and functionality of the land, complex infrastructures are being built, both vertically and horizontally, layered and stacked. These three-dimensional (3D) developments affect the interests (Rights, Restrictions, and Responsibilities (RRRs)) attached to the underlying land. A 3D cadastre will assist in managing the effects of 3D development on a particular extent of land.
There are many elements that contribute to develop a 3D cadastre, such as existing of 3D property legislations, 3D DBMS, 3D visualization. However, data modeling is one of the most important elements of a successful 3D cadastre. As architectural models of houses and high rises help their users visualize the final product, 3D cadastre data model supports 3D cadastre users to understand the structure or behavior of the system and have a template that guides them to construct and implement the 3D cadastre.
