Walkers Point 10-Centimeter Resolution Orthophoto Imagery from 2017

10-centimeter spatial resolution RGB orthophoto mosaic of Walkers Point, captured on May 16, 2017 from approximately 4000 meters. The imagery was orthorectified using a digital terrain model and delivered as 1km x 1km GeoTIFF tiles. Aerometrex produced the data for the Bundaberg Regional Council using a VisionMap A3-Edge sensor.

Use Cases

• Use the 10 cm resolution RGB orthophoto tiles as a high-detail base map for land-use change detection in coastal areas.
• Analyze ground-level spatial features with the stated +/- 3 pixel accuracy for cadastral or environmental mapping applications.
• Assess the impact of relief displacement on elevated structures like rooftops and tree canopies as noted in the data limitations.

Strengths

• High 10-centimeter spatial resolution suitable for detailed feature identification.
• Explicit spatial accuracy of +/- 3 pixels at 68% confidence for ground-level features.
• Standardized 1km x 1km GeoTIFF tile grid facilitates systematic processing.

Limitations

• Spatial accuracy is reduced for elevated structures and in areas of dense vegetation due to relief displacement.
• Single acquisition date (2017-05 16) provides only a historical snapshot, not temporal series.
• Data is limited to the specific geographic area of Walkers Point.
