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...

LADM country profiles development: Aspects to be reflected and considered

The wider recognition and use of ISO 19152 LADM Edition I, is mainly documented through the country profiles that have been developed in multiple jurisdictions across the world. Various approaches for developing country profiles have been followed, without acting in accordance with a specific (official or unofficial) roadmap or methodology. This...

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...

Moving Towards a Fully Operational 3D Digital Cadastre: Victoria, Australia

Population is growing and due to urbanisation, cities are expanding horizontally and vertically to accommodate more population. Managing these crowded cities with many high-rises and infrastructures below and above the ground surface requires efficient systems. However, the current land and property registration systems mainly use two...

A BIM-Driven Approach to Managing Common Properties within Multi-Owned Developments

There has been a significant growth of multi-owned developments in cities around the world. These developments include a combination of different types of residential and commercial uses of urban spaces. Common property areas in multi-owned developments typically include a wide range of shared spaces and facilities. Clear and correct delineation...

Towards LADM Victoria country profile – modelling the spatial information

Managing properties and people’s interests in complex multi-level developments is rapidly increasing the last decade and as a result, current cadastral information systems are facing a growing demand to capture, register, maintain, visualise and disseminate 3D spatial information. This has led to a continuous research, at the international...

Towards a New Working Item Proposal for Edition II of LADM

This paper presents the first and incomplete draft text for the revision of IS 19152:2012 ‘Geographic information — Land Administration Domain Model (LADM)’ within ISO TC211 in the form of a New Working Item Proposal (NWIP). This ‘two-page NWIP’ text aims to describe the scope of proposed project to revise, and also provides the purpose and...

Exploring Options for Standardization of Processes and Transactions in Land Administration

Processes and transactions in Land Administration are outside the scope of the Land Administration Domain Model Edition I published in 2012. Reason is that processes were considered to be country specific. Generic processes would be too difficult to model. This view needs reconsideration – given developments as Fit-For-Purpose Land...

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...

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...

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...

A Roadmap to Accomplish 3D Cadastres

Urbanisation is regarded as a significant global trend. This means cities around the world will be accommodating more population. The population demands accommodations as places for living and business activities. Cities have limited land and therefore high-rise structures have become major infrastructures addressing the needs arsing from...

Bridging the Gap between LADM and Cadastres

The LADM passed, on the 1st of November 2012, the final vote towards becoming an international standard, ISO 19152, and was formally published by ISO on 1ste of December 2012. Since then there has been a considerable move in the land administration domain towards the implementation of the model. Examples are in Australia, China, Malaysia,...

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...
