Abstract: Recent studies in Australia and New Zealand have explored various technological, legal, and institutional aspects of 3D cadastre modernisation. The majority of these studies concentrate on a single jurisdiction. The reason is that each jurisdiction is in charge of its own cadastral system. As a result, each jurisdiction's standards, rules, and processes for implementing 3D digital cadastre are unique. In Australia and New Zealand, however, the Intergovernmental Committee on Surveying and Mapping (ICSM) has established national frameworks for cadastral systems. To implement 3D digital cadastre at a national level, it is vital to identify the variations and commonalities across existing cadastral systems. Comparisons of 3D cadastre for several civil law countries as well as international standards have been undertaken in the present literature. However, common law jurisdictions such as Australian states and New Zealand have not been compared in terms of 3D cadastre. Therefore, the main goal of this study is to propose a multi-jurisdictional framework that includes variations and commonalities in the current methods adopted for subdividing ownership of vertically placed properties in order to support 3D digital cadastre in all Australian and New Zealand jurisdictions. The proposed framework comprises four layers: definition, core, interoperability and jurisdictional. This framework would potentially serve as a starting point for building a nationally integrated digital data ecosystem for 3D cadastre in Australia and New Zealand.
