Modelling 3D legal spaces of Public Law Restrictions within the context of LADM revision

Intense exploitation of land in the vertical direction has brought up complex legal relations between different types of spatial units with various characteristics (e.g., land, marine, air, underground parcels, and infrastructure objects). Therefore, the use of 3D models is required to clearly represent real property and associated Rights,...

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...

Requirements and Opportunities for Web-Based 3D Visualization and Dissemination of Property Valuation Information

The timely and effective dissemination of property values is an essential part of a transparent and efficient property valuation system as property values are required in several land administration processes, such as land acquisition, taxation, transaction, consolidation, readjustment and transformation. In the last decade, a web-based data...

BIM Models as Input for 3D Land Administration Systems for Apartment Registration

The growth of cities and the pressure on land worldwide leads to more complex and multilevel structures with different space interrelations. For the registration of complex spaces mostly 2D Land Administration Systems (LAS) are used, while a representation of space in 3D could provide a clearer insight. Concurrently, technological advancements...
