Bundaberg 2020 Orthophoto Imagery With 6cm Resolution

Imagery from October-November 2020 comprises 2015 RGB images captured at 8300 feet. The orthorectified mosaic has a 6cm spatial resolution and a stated accuracy of 3 pixels at 68% confidence. Data was produced by the Bundaberg Regional Council GIS team.

Use Cases

• Use the 6cm resolution orthophotos as a base map layer for spatial analysis with other GIS data.
• Analyze ground-level features, leveraging the spatial accuracy of 0.081m RMSE in X and 0.027m in Y to existing control.
• Assess landscape changes in the Bundaberg region using imagery from the 2020-10-30 and 2020-11-05 acquisition dates.

Strengths

• High-resolution imagery with a spatial resolution of 6 centimeters.
• Contains 2015 individual RGB images for detailed coverage.
• Provides specific spatial accuracy metrics, including RMSE values of 0.081m in X and 0.027m in Y.

Limitations

• Spatial accuracy is reduced for elevated structures like rooftops and tree canopies due to relief displacement.
• Accuracy is also reduced in areas of dense vegetation, limiting reliable measurement.
• Data is static from late 2020 and does not represent current conditions.
