Resumen
- An easement is an important usufructuary right, and its main purpose is that one party wants to use the property of others to improve the benefits and interests of his own real estate. Because of the increasing population and accelerating urbanization urban planners have focused on the development and utilization of three-dimensional urban space, namely, underground, near ground and aboveground space, to use the spatial resources fully. Therefore, jurisprudence-confined planar easement must be combined with spatial information from two dimensions (2D) to three dimensions (3D), as well as 2D property boundaries to be extended to 3D to adapt to urban development. This paper focuses on the easement of access, which is the right to cross the property to go to and from another, under the context of 3D cadastres. The model of easement spatialization based on BIM (Building Information Model) specified by IFC (Industry Foundation Class) standards is constructed and analysed. The servient owner and the dominant owner of the easement can be linked because they are both attached to the same physical space. This paper takes a multistory building having individually owned condominium units as an example to demonstrate how to access the semantic information associated with the geometric information of 3D property objects in the BIM/IFC. The research results show that BIM/IFC can optimize the complex presentation of 3D property attributes and is an effective carrier of easement spatialization. The combination of legal information and spatial information of 3D properties not only optimizes the operation and maintenance of buildings but also improves land management and accelerates the development of 3D cities.
