Thermal Orthomosaics of Athens Green Spaces During Heatwaves

Twelve urban green spaces in Athens, Greece, are covered by this collection of UAV-derived thermal orthomosaics. The data was created by Eleni Mougiakou of the Agricultural University of Athens and captures conditions during heatwaves from 2023 to 2024. Each orthomosaic is classified into five quantile-based temperature classes to represent relative thermal conditions.

Use Cases

• Analyze spatial patterns of the five quantile-based temperature classes across different green spaces to identify urban heat islands.
• Correlate thermal class distributions with vegetation types or park designs using the georeferenced GeoTIFF data.
• Validate microclimate models by comparing predicted surface temperatures with the classified thermal orthomosaics.
• Assess the cooling performance of specific green spaces by tracking changes in thermal class extents between heatwave events.

Strengths

• Covers twelve distinct urban green spaces for comparative analysis.
• Data is georeferenced (EPSG:2100) for precise spatial integration.
• Provides classified temperature data (five classes) simplifying pattern analysis.

Limitations

• Sample size is limited to twelve locations in a single city.
• Temperature values are relative quantile classes, not absolute measurements.
• Temporal coverage is specific to heatwave conditions over two years.
