Survey Mark GDA2020 Coordinates for NSW Cadastral Control Network

New South Wales survey marks forming the official State control survey network. The dataset provides GDA2020 coordinates, heights, and related information for each mark, as reported in SCIMS. The service supports requests in multiple coordinate reference systems.

Use Cases

• Aligning cadastral survey projects to the official state control network based on mark coordinates.
• Converting coordinate data between GDA2020, GDA94, and WGS84-aligned-to-GDA2020 reference systems.
• Assessing positional accuracy for survey marks based on the provided class and order information.
• Integrating survey control points into GIS environments using the multiCRS web service.

Strengths

• Coordinates are provided in the modern GDA2020 datum.
• The service supports built-in server-side transformations between multiple coordinate reference systems.
• Data controls numerical output precision to mirror the official SCIMS Online system.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• SCIMS Online is noted as the official option for legal traceability, suggesting this service may be a derivative product.
