Antarctic Biopiles Orthophoto and Digital Surface Model from UAV

An orthophoto and Digital Surface Model (DSM) of biopiles and the surrounding area at Casey Station, Antarctica, derived from UAV aerial photographs. The data was created by Dr Arko Lucieer of TerraLuma and the University of Tasmania for the Australian Antarctic Division's Terrestrial and Nearshore Ecosystems research group. The aerial photographs were captured on a single day, February 10, 2013.

Use Cases

• Analyze spatial extent and topography of petroleum-contaminated biopiles using the orthophoto and DSM.
• Monitor changes in the Antarctic landscape by comparing this 2013 orthophoto with later imagery.
• Validate UAV photogrammetry workflows for geospatial data collection in polar regions using the documented camera parameters (ISO-400, 20mm focal length).
• Assess site conditions for the 'Remediation of petroleum contaminants' project (AAS 4036) using the georeferenced imagery.

Strengths

• Includes both an orthophoto and a Digital Surface Model (DSM) for the same area and time.
• Products are georeferenced to ground control points surveyed using differential GPS, enhancing spatial accuracy.
• Detailed photographic metadata is provided (ISO-400, 20mm focal length, f/6.3, 1/1250 sec exposure).

Limitations

• Data is from a single snapshot in time (February 10, 2013), limiting temporal analysis.
• Spatial coverage is limited to the specific biopiles and nearby area at Casey Station.
• The orthophoto has been re-projected to WGS84, which may introduce minor geometric distortions from the original ITRF2000 datum.
