Abstract |
| The accurate representation of complex cadastral data is fundamental to understanding the rights, restrictions, and responsibilities (RRRs) associated with land parcels. While traditional 2D representations are sufficient for simple visualisations, they do not effectively represent complex 3D scenarios such as strata ownership, underground easements, and overlapping rights.
Emerging technologies such as Virtual Reality (VR) and Augmented Reality (AR) offer significant advantages for enhancing 3D cadastral visualisation. These immersive environments provide a more intuitive way to interact with spatial data which can improve user comprehension of complex relationships between land parcels and associated RRRs. To address this, this paper explores how emerging technologies can be applied in real world contexts.
As jurisdictions increasingly implement spatial digital twins to support land administration systems, there is a need to optimise the visualisation of cadastral data within a 3D environment. This paper provides a case study demonstrating the use of VR via Unreal Engine 5 to visualise 3D cadastral data in New South Wales, Australia. The case study combines contextual data, including a digital elevation model (DEM), building information model (BIM), and reality mesh, with cadastral data representing strata, stratum, and torrens lot boundaries digitised from registered plans of survey. The prototype has been developed through a comprehensive review of existing literature to assess the application of established visualisation parameters.
By exploring how existing visualisation methods and technical requirements from literature can be applied in a VR environment, this paper provides insight into the potential of immersive technologies. It highlights how these technologies can transform the understanding and interaction with cadastral information in a 3D environment, contributing to the future of cadastral systems in a digital world. |
