The 3D Cadastral Survey Data Model and Exchange (3D CSDM) work aims to create a widely adopted standard across Australia and New Zealand for exchanging digital cadastral survey information between the survey industry and government land administration agencies.
Toitū Te Whenua Land Information New Zealand (LINZ) is leading the project in partnership with Department of Environment, Land, Water and Planning (Victoria), the Department of Customer Service (New South Wales), Landgate (Western Australia), and the Department of Resources (Queensland).
The project has two primary objectives:
- To develop a harmonised data model that covers all cadastral survey data components across all New Zealand and Australian jurisdictions. This includes both 2D and 3D elements.
- To identify options for encoding and exchanging the data in the model in liaison with survey software vendors.
SURROUND NZ Ltd is developing the 3D CSDM as the lead of a five-company consortium.
The programme of work has been established by the Intergovernmental Committee for Survey and Mapping (ICSM) with support from the Spatial Information Council (ANZLIC). Implementation of the new framework for exchanging cadastral survey information will be up to individual jurisdictions.
The work is planned for completion by early 2022.
