An LADM-based Approach for Developing and Implementing a National 3D Cadastre – A Case Study of Malaysia

With the growing dominance of multi-storey buildings and other infrastructures, 2D-based cadastral systems are facing new challenges in recording, managing and visualising the spatial extent of vertically stratified cadastral spaces. In Malaysia, surveying and cadastral measurements are currently stored in the National Digital Cadastral Data...

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...

Development of a 3D ePlan/LandXML Visualisation System in Australia

The importance of managing properties and people’s interests in complex multi-level developments is increasing, due to population growth and shortage of land in urban areas. As a result, cadastral systems are under pressure to change the way they capture, register and visualise 3D data of these multi-level scenarios. However, interests in land...

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...
