Successful economies rely on effective land administration systems. A key contributor to land administration is the cadastral system and its support for the ongoing definition of boundaries that support secure property rights and effective land management.

Cadastral systems are complex and typically have significant differences in legislation, regulation and survey practices between jurisdictions. And yet the high-level objectives of a cadastral system tend to be essentially the same the world over. Comparisons of cadastral systems in different jurisdictions can easily become focused on the technical, legal, or implementation differences. This can obscure commonalities and opportunities to develop common strategies for the efficient maintenance and development of cadastral systems.

Changes in technology have significantly altered the way that cadastral boundaries can be marked and located in the real world and then represented or visualised on maps or plans and in databases. The rate of take up of these technologies, and the form of that take up, varies between jurisdictions.

A conceptual model to explore the complex relationships between different representations of cadastral boundaries has been developed. This model, which has broad application, is known as the Cadastral Triangular Model (CTM). The CTM is a valuable tool to explore and resolve complex issues facing cadastral systems, for example proposals for the evolution of 3D cadastres. This paper describes the CTM, how it can be used and identifies further applications of this model to address contemporary issues confronting cadastral authorities.
