3D CSDM December 2021 Project Update

Survey software suppliers (Technology partners) engagement and progress to date.

The 3D Cadastral Survey Data Model and Exchange (3D CSDM) programme aims to create a widely adopted standard across Australia and New Zealand for exchanging 2D and 3D digital cadastral survey data between survey industry and government land administration agencies. It is therefore recognised that survey software suppliers support and buy-in is extremely important for the implementation of the 3D CSDM.

During May 2021, a questionnaire was distributed to survey software suppliers across the jurisdictions in Australia and New Zealand.

The purpose of the questionnaire was to elicit an understanding of survey software suppliers’ views regarding data and exchange standards relevant to cadastral survey data and gain insight into where they saw the spatial data landscape heading over time.

Forty three individuals across 24 organisations received the questionnaire, which contained 30 questions. Approximately 50% responded providing valuable feedback, which has been shared with all survey software suppliers and summarised as follows:

  • Adoption timeframes for the model and encoding options we intend to release are uncertain. Survey software suppliers are responsive to customer demand and suggest that to drive this capability, the jurisdictions will need to develop an implementation programme and that this should include concepts for the new exchange to have a compulsory aspect.
  • Understanding how survey customers use software is a pathway to a new way of working developed in conjunction with using a new standard. Ease of use and respect for existing proven workflows and processes are key non-functional requirements.
  • It is apparent that alignment with exchange standards is a complex space, but strong feedback indicated this was a core aspect for survey software suppliers in providing fit for purpose tools for their customers.
  • It appears that there is a good understanding of the technical environment surveyors are required to comply with including aspects such as dynamic datums and metadata required for cadastral datasets.
  • The feedback indicated at present there isn’t a strong case for API interfacing of survey software to data sources, but a future can be seen where this can be built into systems.

In terms of progress, the project continues to derive the requirements for the proposed model from the nine participating ICSM jurisdictions. The Surround project team is incorporating this into a solution that will provide a maintainable standard driven by a linked conceptual and logical data model.

It is important for the project to identify and work towards removing barriers that may inhibit survey software suppliers from being able to implement the model in their solutions and exchanging the data with jurisdictions. Surround are now inviting feedback on the draft model from survey software suppliers.
