The dataset contains orthomosaics generated from images captured during the XXXIV Spanish Antarctic Campaign. It was produced by the organization SCIOPS using sensors aboard UAVs across 42 flights over seven specific areas of Deception Island. The data was last updated in February 2021.
Use Cases
- Monitor penguin colony extent and terrain changes at Vapour Col and Baily Head using sequential orthomosaic imagery.
- Analyze geothermal activity and landscape features in Fumarole Bay and Murature's Region from UAV-captured image data.
- Map and characterize the crater and lakes like Crater and Irizar Lake for hydrological and geological studies.
- Assess infrastructure and environmental impact around the Antarctic Spanish Base Gabriel de Castilla using georeferenced orthomosaics.
Strengths
- Covers 42 distinct UAV flights providing multiple data collection events.
- Surveys seven named geographic regions on Deception Island, offering specific site coverage.
Limitations
- The exact number of images, resolution details, and orthomosaic file sizes are unknown.
- Data is from a single campaign (XXXIV) with no stated update frequency, limiting temporal analysis.
