Buxton 2017 Orthophoto Imagery With 10-Centimeter Resolution

10-centimeter spatial resolution orthophoto imagery of Buxton, captured on May 16, 2017. The dataset consists of 1km x 1km GeoTIFF tiles rectified using a digital terrain model and VisionMap A3-Edge sensor data. Aerometrex produced this map-accurate imagery for the Bundaberg Regional Council.

Use Cases

• Create a high-resolution base map layer for urban planning by overlaying other spatial data on the 10 cm resolution orthophotos.
• Analyze ground-level feature changes over time using the 2017-05-16 acquisition date as a temporal benchmark.
• Assess spatial accuracy for terrain features, noting the stated 3-pixel accuracy at ground level and its limitations for elevated structures.
• Perform land cover classification in non-vegetated areas, acknowledging reduced accuracy in regions of dense vegetation.

Strengths

• High 10-centimeter spatial resolution for ground-level features.
• Map-accurate orthorectification using a digital terrain model and commercial photogrammetric software.
• Stated spatial accuracy of 3 pixels at 68% confidence for ground-level features.
• Systematic 1km x 1km GeoTIFF tile grid structure.

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 reliable measurement.
• Single acquisition date (2017) limits temporal analysis without contemporary data.
