Bundaberg 2018 Aerial Orthophotography at 6cm Resolution

2018-08-17 and 2018-08-18 imagery captured by a PhaseOne IXU-RS1000 sensor from approximately 5000ft MSL. The dataset provides orthorectified RGB imagery with a spatial resolution of 6 centimeters, processed using a client-supplied LIDAR digital terrain model. It was produced by the Bundaberg Regional Council GIS team.

Use Cases

• Generate high-resolution base maps for urban planning using the 6cm spatial resolution orthophotos.
• Assess terrain feature accuracy for ground-level objects using the stated horizontal and vertical rectification surface accuracies.
• Analyze aerial capture patterns and coverage from the specified 88 north-south runs and 7 tie/coastal strips.
• Evaluate sensor performance and calibration using the documented focal length of 69.8261mm and imagery type (RGB).

Strengths

• High spatial resolution of 6 centimeters per pixel.
• Specific acquisition dates (2018-08-17 and 2018-08-18) and sensor details (PhaseOne IXU-RS1000).
• Documented spatial accuracy of less than 3 pixels at 68% confidence.
• Detailed capture methodology with 88 north-south runs and 7 tie/coastal strips.

Limitations

• Spatial accuracy is reduced in areas of dense vegetation and is not reliable for measuring elevated structures like rooftops or tree canopies.
• Rectification accuracy metrics are based on client-supplied metadata and were not independently verified.
• The dataset's utility is temporally limited to conditions and features present in August 2018.
