Casey Station Disturbance Footprint GIS Layers from 2002 to 2018

AU_AADC provides GIS spatial layers mapping medium and heavy disturbance footprints around Casey Research Station in Antarctica. The dataset covers four snapshot years: 2002, 2008, 2015, and 2018. The layers were primarily digitized by S. Brooks from satellite, UAV, and aerial imagery.

Use Cases

• Analyze temporal changes in the heavy_disturbance and medium_disturbance footprint layers between 2002, 2008, 2015, and 2018.
• Assess the impact of different data collection methods, comparing digitized satellite imagery from 2018 with ground-truthed field measurements from 2008.
• Model the influence of snow cover on observed disturbance area by comparing footprint layers from different seasons and years.
• Use the spatial layers to correlate disturbance zones with other environmental datasets for impact assessment around Casey Station.

Strengths

• Four distinct temporal snapshots (2002, 2008, 2015, 2018) enable longitudinal analysis.
• Includes both medium and heavy disturbance classifications for each year.
• 2008 data incorporates ground-truth field measurements for validation.

Limitations

• Limited to four discrete years, lacking continuous annual coverage.
• Footprint visibility and digitization accuracy are noted to be affected by variable snow cover.
• Unknown total spatial extent or polygon count for the GIS layers.
