NSW Transport Crossing Structures: Bridges, Tunnels, Culverts, and Fords

A point feature dataset published on 06/02/2020 representing locations where roads and railways intersect or cross other features in New South Wales. The dataset includes structures such as Rail Bridges, Road Bridges, Tunnels, Culverts, Floodways, and Fords, positioned within cadastral parcels. It is maintained by Spatial Services, a business unit of the Department of Customer Service NSW, and aligns with the national GDA2020 spatial standard.

Use Cases

• Mapping and analyzing the distribution of rail bridges and tunnels across NSW based on the listed feature types.
• Assessing road infrastructure density by counting road culverts and floodways.
• Identifying potential safety or maintenance hotspots at level crossings where roads and railways intersect.
• Integrating crossing data with other transport theme datasets for comprehensive network modeling.
• Planning new infrastructure projects by referencing existing crossing structures and their locations.

Strengths

• Data accuracy is defined by map scale standards, with positional accuracy ranging from 0.25m at 1:500 scale to 50m at 1:100,000 scale.
• The dataset is part of the Foundation Spatial Data Framework (FSDF), suggesting adherence to standardized data models.
• An ongoing program aims to upgrade spatial location and accuracy, indicating active maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data currency date is listed as 01/01/3000, which is likely a placeholder and indicates actual data freshness should be verified.
