NSW Survey Marks with GDA94 Coordinates and MultiCRS Support

New South Wales survey marks forming the official State control survey network, as reported in SCIMS. The dataset provides GDA94 coordinates, heights, and related information but is noted as no longer maintained and superseded by GDA2020 versions. The service is published by Spatial Services (DCS) and supports requests in multiple Coordinate Reference Systems.

Use Cases

• Transform historical survey coordinates between GDA94 and GDA2020 datums based on the described server-side NTv2-CPD transformations.
• Reference legacy survey mark locations for planning or validation based on the described official State control survey network.
• Align GIS environments using GDA94, GDA2020, or WGS 84-aligned-to-GDA2020 based on the described multiCRS service functionality.

Strengths

• Provides official State control survey network data, as reported in SCIMS.
• Supports multiple Coordinate Reference Systems (GDA94, GDA2020, WGS 84-aligned-to-GDA2020) via built-in server-side transformations.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• GDA94 coordinates are explicitly noted as no longer maintained and have been superseded.
• Column-level documentation is absent; field semantics must be inferred after download.
