Bundaberg 2019 Aerial Orthophotos With 6cm Resolution

Aerial imagery of Bundaberg captured in July 2019, orthorectified to a 6cm spatial resolution. The dataset includes primary and secondary flight runs totaling 105 captures, using a PhaseOne IXU-RS1000 sensor. It was produced by the Bundaberg Regional Council for use as a geospatially accurate backdrop layer.

Use Cases

• Create high-resolution land cover maps using the 6cm RGB orthophotos as a base layer.
• Analyze terrain changes in mines or quarries by comparing the photogrammetrically derived DSM against the base Lidar surface.
• Assess spatial accuracy for ground-level features against the stated <3 pixel accuracy at 68% confidence.
• Use the 1km2 tile grid for efficient large-area mosaic assembly and distribution.

Strengths

• High 6cm spatial resolution for detailed feature observation.
• Stated spatial accuracy of <3 pixels at 68% confidence for ground features.
• Utilizes a 1m Lidar DSM for orthorectification, providing a geometric foundation.

Limitations

• Spatial accuracy is reduced for elevated structures like rooftops and tree canopies due to relief displacement.
• Accuracy is degraded in areas of dense vegetation.
• The rectification surface accuracy metrics are based on client metadata and were not independently verified.
