Requirements Based Design of the LADM Edition II

This paper examines the requirements based design of the LADM Edition II. The requirements are the starting point for the Abstract Test Suite (ATS, Annex A in an ISO standard). The requirements/ATS can be used to assess if a given LADM country profile with a specific application schema is conformant with the LADM standard. The requirements are a...

Modelling 3D legal spaces of Public Law Restrictions within the context of LADM revision

Intense exploitation of land in the vertical direction has brought up complex legal relations between different types of spatial units with various characteristics (e.g., land, marine, air, underground parcels, and infrastructure objects). Therefore, the use of 3D models is required to clearly represent real property and associated Rights,...

Initial Design to Develop a Cadastral System that Supports Digital Cadastre, 3D and Provenance for Singapore

It is challenging to design and develop a cadastral system that supports digital cadastre, 3D and provenance. Digital cadastre encodes cadastral information in digital format like LandXML, which allows for automation and returns high productivity. 3D enables capturing and representing the third dimension, which is critical for the development in...

Capturing Legal and Physical Boundary Differences in 3D Space – A Case Study of Trinidad and Tobago

Technology has simplified the construction of a 3D cadastre by allowing rapid, remote capture of the data required for the graphic components of the system. Research into using 3D information generated from laser scanning, LiDAr and satellite imagery, and aerial photography for Building Information Management (BIM) has advanced considerably over...

Visibility Analysis in a 3D Cadastre

The implementation of a 3D cadastre is work-intensive and expensive and legitimation of such expenses is necessary. A legitimate path of argumentation is that 2D systems fail to communicate complex legal situations correctly. Also, additional arguments can help to strengthen the position of 3D cadastres and provide support from other professions...

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...

SLRB Bahrain – 3D Property Registration System

Technical Affairs Directorate or TAD of Survey and Land Registration Bureau or SLRB in Bahrain is responsible for maintaining property transactions repository. This repository records and reports all properties transactions related to ownership rights and restrictions in the kingdom. Property transactions repository was made digital by...

Visualization Principles in 3D Cadastre: A First Assessment of Visual Variables

This paper proposes to investigate which among visual variables are more appropriate (if they are) for geo-visualization of 3D legal units in a probable 3D cadastre system. Visual variables, as proposed by Bertin (1983), include position, size, shape, value, color, orientation and texture. The appropriateness is evaluated base on whether a...

Delivering 3D Land and Property Management: A Consideration of Institutional Challenges in an Australian Context

Urbanisation presents myriad challenges for countries, primarily by increasing pressure on limited land resources through demands for housing, services and infrastructure. This is exacerbated in city centres, where land values are often highest, resulting in acute needs to effectively manage land resources while capitalising on land and property...

ArcGIS for Land Records: Current Status and Future 3D Considerations

3D cadastre is necessary to display and manage complex spatial relationships. To support a full 3D cadastral implementation, object boundary definitions, object topologies and their legal representations will have to be further defined. A hybrid approach combining 2D and 3D using GIS represents a feasible, economical and extensible approach....
