Woodgate 2020 Aerial Orthophoto Imagery

253 RGB aerial images captured on 2020-11-05 at 8300 feet above MSL. The orthorectified mosaic has a 6 cm spatial resolution and a spatial accuracy of 3 pixels at 68% confidence, rectified using a digital ground surface model.

Use Cases

• Generate high-resolution base maps using the 6 cm spatial resolution orthophoto for spatial analysis.
• Assess ground-level feature accuracy against the stated 3-pixel spatial accuracy metric for validation.
• Analyze imagery captured with a 300 mm focal length sensor for photogrammetric applications.
• Use the Web Mercator Auxiliary Sphere projected tiles as a backdrop layer for other geographic data.

Strengths

• Contains 253 individual high-resolution aerial images.
• Offers a very high spatial resolution of 6 centimeters per pixel.
• Provides a defined spatial accuracy of 3 pixels at a 68% confidence level.
• Imagery was captured with a 300 mm focal length sensor and 56%/65.5% overlap for photogrammetry.

Limitations

• Spatial accuracy is reduced in areas of dense vegetation and is not reliable for measuring elevated structures like rooftops.
• The dataset is a single snapshot from November 2020, offering no temporal series for change detection.
• Data is limited to the Woodgate geographic area captured during the specified flight.
