Evaluation of the International 3D Geospatial Data Models and IFC Standard for Implementing an LADM-based 3D Digital Cadastre

Land Administration Domain Model (LADM) is an international standard for defining both semantic and spatial information connected with rights, restrictions, and responsibilities (RRRs) that affect land, water, built assets, natural resources, underground spaces, and airspaces. Since LADM is currently a conceptual land administration model, one...

3D Registration of Apartment Rights Using BIM/IFC: Comparing the Cases of the Netherlands, Saudi Arabia, and Turkey

Τhe built environment has a vast and ever-growing number of complex and multi-layered buildings and other structures. The number of those is growing because of the increasing pressure on the limited space in cities. It is important to note that different professional sectors are involved in the realization of a new building. These sectors are...

Modelling 3D underground legal spaces in 3D Land Administration Systems

Two dimensional (2D) Land Administration Systems (LASs) do not adequately represent 3D underground objects. It is not easy to identify the owners of these objects and the relations between objects below and above the surface are not explicitly provided. A 3D LAS can however facilitate a better understanding, as well as a more efficient...

Linking LADM with BIM/IFC standards for mobile-based 3D Crowdsourced Cadastral Surveys

The ongoing urbanization has led to the emergence of several complex constructions and multi-dimensional property rights. Traditional cadastral procedures cannot meet the demands of this new reality, leading to increased costs and long delays. Exploiting the capabilities of the latest technologies, mobile services (m-services), Building...

Easement spatialization with two cases based on BIM

An Easement is a kind of 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. With increasing population and accelerating urbanization, the limitation of urban space has gradually become prominent problem. To use the spatial resources fully,...

Connecting LADM and IFC Standards – Pathways towards an Integrated Legal-Physical Model

In 3D digital land and property registration systems, simultaneous representation of both legal spaces and physical elements can aid understanding of the spatial extent of property rights, restrictions and responsibilities (RRR). The integration of legal and physical objects can be done only at visualisation level without defining any semantic...
