Woodgate 2014 Aerial Imagery With 6-Centimeter Resolution

142,904 RGB aerial images were captured over Woodgate in April and May 2014 using a 300mm focal length sensor. The imagery has been orthorectified into a 1km x 1km tile grid with a 6 cm spatial resolution. The dataset was produced by the Bundaberg Regional Council using a digital ground surface model for rectification.

Use Cases

• Train a semantic segmentation model on the RGB imagery to classify land cover types like vegetation and structures.
• Analyze spatial accuracy of ground-level features against the stated 18cm accuracy metric for validation studies.
• Use the orthorectified tiles as a high-resolution base map layer for local environmental or urban planning.
• Assess the impact of relief displacement on elevated structures like rooftops and tree canopies as noted in the limitations.

Strengths

• Contains 142,904 individual aerial images for detailed coverage.
• Offers a high 6 cm spatial resolution for fine-grained analysis.
• Imagery is orthorectified, combining photographic and geometric map qualities.

Limitations

• Spatial accuracy is reduced in areas of dense vegetation and is not reliable for measuring elevated structures.
• The accuracy of the rectification surface (client-supplied DTM) is explicitly stated as unknown.
• The dataset's temporal coverage is limited to two specific dates in 2014.
