3D DIGITAL CADASTRE JOURNEY IN VICTORIA, AUSTRALIA Dr Davood Shojaei, Land Use Victoria
Cadastral System in Victoria Land Use Victoria More than 3.5 million land parcels Population: more than 6.2 million (ABS, 2017) Monument based cadastre
Victorian Cadastral Data (Paper à Digital) The first sales of land in VIC Vicmap Property dataset creation PDF Plans through SPEAR eplan investigation commenced eplan as a supplementary document in SPEAR SPEAR fully eplan enabled The 3D Digital cadastre investigation commenced Mapbase upgrade pilot project commenced Title information migrated to VOTS eplan Paper-based plans PDF-based plans BIM? 3D eplan? 1851 1990 2000 2004 2008 2011 2013 2014 2016

3D DIGITAL CADASTRE INVESTIGATION IN VICTORIA CURRENT STATUS & RESEARCH OUTCOMES
3D Data Modelling eplan Data Model (LandXML) Building Information Modelling (IFC) LandInfra (InfraGML)
3D Data Modelling (Shojaei, Olfat, Rajabifard, Darvill, Briffa (2016) Assessment of the Australian digital cadastre protocol (eplan) in terms of supporting 3D building subdivisions)
3D Data Visualisation
3D Data Validation
3D Validation Rules 1 - Created Parcels for Cancelled Parcels 2 - All Faces must be Flat 3 - Parcel Geometry Closure 4 - Parcel Collision (Clash) (Shojaei, Olfat, Faundez, Kalantari, Rajabifard, Briffa (2017), Geometrical Data Validation in 3D Digital Cadastre A Case Study for Victoria, Australia)
FUTURE DIRECTIONS
3D Data Model and Data Format for 3D Cadastre
3D Digital Registration of Infrastructures Utility Networks Easements Other Infrastructures Bridges Tunnels
Enhancing the 3D eplan Visualisation Prototype Enhancing the prototype according to the feedback received from stakeholders
Improving 3D Data Visualisation Using new techniques in visualisation such as Augmented Reality and Virtual Reality to develop applications for 3D digital cadastre purpose (Ref: macfunamizu.com/2009/09/04/red-dot-design-concept-award-2009/)
3D Data Validation Extending the current 2D digital cadastre (eplan) validation rules for supporting building subdivisions
3D Data Storage
Investigating Legal Aspect What would be the legal point of truth for registration of ownership rights? 3D model or 2D plans (PDF/TIFF)? What should be included to the contract of sale as part of transferring ownership, and marketing? Can all stakeholders and courts use 3D legal models for their decision-making process? Do 3D models intend to replace or supplement 2D plans? What are the required changes to the existing regulations to move to 3D? What are the main industry bodies for driving this change and to facilitate its implementation? How should 3D legal disputes be handled? How to raise awareness of 3D legal disputes among professions, e.g. land surveyors, developers, planners?
Investigating Institutional Aspect The institutional aspect looks at what processes and roles should change to facilitate the implementation. An institutional framework is required Apply the framework in institutional operations of land and property registration
Road Map
Collaboration with Universities ARC Linkage Projects: Land and Property Information in 3D 3D Property Ownership Map Base for Smart Urban Land Administration PhD student s research projects: 3D cadastral data modelling 3D cadastral visualisation: understanding users requirements Towards 3D-enabled urban land administration: invisible constraints and strategic choices Building information modelling for urban land administration
Collaboration with Universities (Cont.) BSc student s research projects: eplan the challenges and opportunities in creating plans of subdivision in Victoria A comparative study of SPEAR eplan and NZ e-survey Investigating the benefits of eplan for small firms Supporting building subdivision plans in eplan Investigating BIM to provide information for 3D cadastre
