Development of an LADM-based conceptual data model for 3D underground land administration in Victoria

Currently, many cities around the world use underground space for different applications such as tunnels, utility networks, parking, walkways, and shopping malls. Due to the increasing use of underground areas, management of this space is very important for decision-makers and stakeholders. A 3D Underground Land Administration (ULA) data model...

Design and Implementation of a 3D National Digital Cadastral Database based on Land Administration Domain Model: Lessons Learned from a 3D Cadaster Project in Malaysia

With the growing dominance of urban infrastructures in Malaysia, 2D-based cadastral systems in this country are facing new challenges in recording, managing and visualizing the spatial extent of urban land parcels. In Malaysia, surveying and cadastral measurements are currently stored in the National Digital Cadastral Data Base (NDCDB), which is...

3D Cadastre Visualization: Recent Progress and Future Directions

The 3D Cadastre has been investigated from many viewpoints (including legal, organizational and technical). However, to date little research has focused specifically on visualizationrelated aspects despite the value-added of the third dimension. The paper first proposes an overview of progress made in the last five years in 3D cadastral...

Comparing Three Types of BIM-based Models for Managing 3D Ownership Interests in Multi-level Buildings

There are various 3D spatial data models to support digital management of legal and physical aspects of buildings. These data models adopt three possible approaches to represent and manage spatial dimension of 3D ownership interests, namely pure legal, pure physical and integrated methods. Building Information Modelling (BIM) is a method for...

Development of XML Schemas for Implementation of a 3D Cadastral Data Model

A 3D cadastral data model (3DCDM) was developed to support integration of legal and physical information that are required for 3D cadastral applications. The 3DCDM model has twelve sub-models or modules including 3DCDM Geometry Model, 3DCDM Root Model, 3DCDM LegalPropertyObject Model, 3DCDM InterestHolder Model, 3DCDM Survey Model, 3DCDM...

3D Cadastres and Beyond

How does the cadastre deal with an urban environment that is increasingly populated and structurally complex? The development and implementation of 3D digital cadastres is now positioned as a necessary – and urgent – response: it is no longer just about land; it can be expected that in the future, the majority of lots created will be associated...

Advanced Principles of 3D Cadastral Data Modelling

Current cadastral data models use a 2D land-parcel definition and extend it to cover 3D requirements. This approach cannot adequately manage and represent the spatial extent of 3D land rights, restrictions and responsibilities (3D RRRs). This paper aims to develop a 3D Cadastral Data Model (3DCDM) to configure 3D cadastral frameworks, manage and...
