Antarctic Orthomosaics from UAV Flights on Livingston Island

42 UAV flights were conducted over Livingston and Deception Islands in Antarctica, capturing aerial imagery for orthomosaic generation. The dataset contains orthomosaics created from images obtained by various sensors onboard unmanned aerial vehicles. It was reported by the organization SCIOPS and last updated in March 2022.

Use Cases

• Analyze geomorphological changes by comparing orthomosaic features from different flight dates.
• Train object detection models to identify specific Antarctic base structures like BAE Juan Carlos I or Refugio base within the imagery.
• Monitor glacial and snow cover extent at sites like Nevero Caleta Argentina using the high-resolution orthomosaic data.
• Validate satellite-derived land cover classifications by using the UAV-based orthomosaics as ground truth reference data.

Strengths

• Covers 42 distinct UAV flight missions, providing multiple data collection events.
• Includes data from multiple specific Antarctic sites such as Punta Hannah and Miers Bluff.

Limitations

• The specific number of orthomosaic files, their spatial resolution, and file sizes are unknown.
• The dataset description lacks details on sensor types, spectral bands, and ground control point accuracy.
