Flagstaff Hill Fort Wollongong Terrestrial LiDAR Scan, 2023

Terrestrial LiDAR point cloud data captured by Wollongong City Council surveyors in May 2023 using a Leica P30 scanner. The dataset includes scans of Flagstaff Hill Fort, with underground scans recorded with intensity only due to insufficient lighting. The data has been thinned for presentation purposes.

Use Cases

• Create 3D models of the historic fort structure based on terrestrial LiDAR scans.
• Analyze terrain and structural features for conservation planning based on point cloud data.
• Perform volumetric analysis of underground spaces using intensity-only LiDAR data.
• Integrate thinned point clouds into visualisation platforms for public presentation.

Strengths

• Data collected using a professional-grade Leica P30 scanner, suggesting high precision.
• Includes both terrestrial and underground LiDAR scans, providing comprehensive site coverage.
• Spatial reference systems (GDA94, WGS84, EPSG:3857) are explicitly defined.

Limitations

• Data has been thinned for visualisation performance, which may reduce point density and detail.
• Underground scans contain intensity data only, lacking colour information.
• Column-level documentation is absent; field semantics must be inferred after download.
