Casey Station Environmental Disturbance Footprints from 2002 to 2018

AU_AADC provides GIS-derived measurements of medium and heavy disturbance footprints surrounding Casey Research Station in Antarctica for the years 2002, 2008, 2015, and 2018. The data was primarily digitized by S. Brooks from satellite, UAV, and aerial orthophoto imagery, with the 2008 data incorporating ground-truth field measurements. The latest data point is from January 2018.

Use Cases

• Analyze temporal changes in heavy_disturbance and medium_disturbance area to assess station impact over a 16-year period.
• Compare footprint delineation methodologies, such as digitization from Worldview-3 imagery versus ground-truthed field measurements from 2008.
• Model the influence of snow_cover on detected disturbance area by cross-referencing footprint layers with seasonal data.
• Validate environmental management policies by tracking the spatial extent of station activities across four snapshot years.

Strengths

• Provides consistent footprint measurements across four distinct years (2002, 2008, 2015, 2018) spanning 16 years.
• Includes data from multiple sources: satellite imagery (Worldview-3), UAV imagery, aerial orthophotos, and ground-truth field measurements.

Limitations

• Dataset contains only four temporal snapshots, lacking continuous annual monitoring.
• Methodological consistency varies, with the 2008 data using a different collection approach (field measurements) than the other years.
• Spatial accuracy for some years may be affected by snow_cover hiding areas of disturbance.
