Yandaran Aerial Orthophotography from May 2017

Bundaberg Regional Council Open Data provides aerial orthophotography captured over Yandaran on 2017-05 16. The imagery is RGB, captured from 2440m with a 300mm focal length sensor and rectified to a 6 cm spatial resolution. The product consists of 1km x 1km GeoTIFF tiles with a stated spatial accuracy of +/- 3 pixels at 68% confidence.

Use Cases

• Create high-resolution base maps by mosaicking the 1km x 1km GeoTIFF tiles for land use analysis.
• Assess ground-level feature accuracy using the stated +/- 3 pixel spatial accuracy metric for validation studies.
• Analyze terrain representation by comparing the orthorectified RGB imagery against the supplied DTM rectification surface.
• Identify areas of potential spatial inaccuracy in regions with dense vegetation, as noted in the dataset limitations.

Strengths

• High spatial resolution of 6 cm per pixel for detailed ground feature observation.
• Explicit spatial accuracy metric of +/- 3 pixels at a 68% confidence level.
• Systematic tile grid of 1km x 1km GeoTIFF files for standardized processing.

Limitations

• Spatial accuracy is reduced for elevated structures like rooftops and tree canopies due to relief displacement.
• Accuracy is explicitly reduced in areas of dense vegetation, limiting reliability for those features.
• Single acquisition date from May 2017 provides only a historical snapshot, not current conditions.
