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...

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...

Modelling the legal spaces of 3D underground objects in 3D land administration systems

One of the significant challenges in current 2D Land Administration Systems (LAS) is defining and registering the Rights, Restrictions and Responsibilities (RRRs) attached to the underground objects. A 3D LAS can facilitate a better understanding, as well as a more efficient registration and clear visualisation of the RRRs than a 2D LAS,...
