Moore Park 2014 Aerial Imagery With 6 Centimeter Resolution

2014-04 aerial imagery collection contains 142,904 RGB images captured at approximately 3800 meters above mean sea level. The orthorectified mosaic has a spatial resolution of 6 centimeters and a stated ground-level spatial accuracy of 18 centimeters. Data was produced by the Bundaberg Regional Council using a 300mm focal length sensor.

Use Cases

• Generate high-resolution base maps for land-use planning using the 6 cm spatial resolution orthomosaic.
• Analyze ground-level feature changes over time by comparing this 2014-04-20 acquisition with newer imagery.
• Assess the impact of terrain models on orthorectification accuracy using the client-supplied DTM referenced in the rectification process.

Strengths

• Large collection of 142,904 individual aerial images.
• High spatial resolution of 6 centimeters for detailed ground feature observation.
• Imagery was orthorectified using a digital terrain model to correct geometric displacement.

Limitations

• Spatial accuracy of 18 cm is only reliable for ground-level features; elevated structures like rooftops are affected by relief displacement.
• Accuracy is reduced in areas of dense vegetation, limiting usability for certain environmental analyses.
• The accuracy of the client-supplied digital terrain model used for rectification is unknown.
