NSW Survey Marks: Geodetic Control Network

New South Wales, Australia's official state control survey network is documented in this dataset. It provides precise coordinates, heights, and metadata for permanent survey marks, sourced from the authoritative Survey Control Information Management System (SCIMS). The service supports multiple coordinate reference systems, including GDA2020 and GDA94, for integration into spatial applications.

Use Cases

• Cadastral survey planning based on official mark locations and status.
• Integrating precise control points into GIS platforms using the multi-CRS web service.
• Verifying the accuracy and class of survey marks for engineering projects.
• Assessing mark availability and condition (e.g., destroyed, restricted) for field work.

Strengths

• Serves as the single source of truth for NSW's state control survey network, sourced directly from SCIMS.
• Supports multiple coordinate reference systems (GDA2020, GDA94, WGS84), enhancing interoperability.
• Managed by Spatial Services (DCS), an authoritative government organization.

Limitations

• Key metadata such as row count, specific column names, and license information is unavailable from the sources.
• One version of the service is marked as 'RETIRING', indicating potential instability or migration requirements.
• The dataset's description warns that SCIMS Online is the official option for legal traceability, suggesting this service may have limitations for formal cadastral work.
