Hill 60 Tunnels: LiDAR Scans of Disused Military Infrastructure

Wollongong City Council provides LiDAR scans of disused military tunnels, gun emplacements, and buildings at Hill 60 in Port Kembla, captured using a Leica P30 scanner. The dataset is a 3D point cloud, colorized by intensity and filtered to 1 in 10 points from the original scan. It documents hazardous, graffiti-covered sites closed to the public, with data current to September 2023.

Use Cases

• Virtual preservation and structural analysis of hazardous historical tunnels based on the 3D point cloud.
• Military history research on gun emplacement layouts and tunnel networks using geospatial data.
• Condition assessment of graffiti-covered surfaces and structural integrity from intensity-colored scans.
• Creating digital twins for public education about sites closed due to safety hazards.

Strengths

• Captured with a specific Leica P30 scanner, indicating professional-grade equipment.
• Original point clouds were filtered to 1 in 10 points to balance detail and system performance.
• Data is georeferenced with explicit spatial reference systems (GDA94, WGS84, EPSG:3857).

Limitations

• Metadata completeness is low: row count, file size, and specific license terms are not provided.
• The point cloud is a downsampled version (1 in 10 points), reducing the original resolution.
• Dataset has a restricted access policy and no planned updates, limiting availability and freshness.
