Fusing spectral and structural airborne imagery data to detect escalating canopy dieback i

8.7 MB of fused aerial hyperspectral and LiDAR data for a genetically unique Eucalyptus macrorhyncha population in South Australia. The dataset, authored by Donna Fitzgerald and last updated in April 2026, supports pixel-based classification of canopy health into three classes with reported high accuracy (Kappa = 0.88 in 2022; 0.81 in 2025). It captures changes in canopy condition between two surveys conducted in 2022 and 2025 under shifting drought conditions.

Use Cases

• Training machine learning models for pixel-based classification of canopy health based on fused spectral and structural variables.
• Analyzing spatial patterns of forest decline and recovery based on slope aspect and moisture gradients mentioned in the description.
• Investigating the relationship between biomass changes (from LiDAR) and canopy greenness (from hyperspectral data) under drought stress.
• Monitoring temporal changes in forest vulnerability to climate change between 2022 and 2025.

Strengths

• Data fusion of high-resolution hyperspectral and LiDAR datasets provides complementary indicators of canopy condition.
• Pixel-based classification achieved reported high accuracy (Kappa = 0.88 and 0.81) for the two survey years.
• Captures a specific temporal comparison showing a >14% decline in healthy canopy and a >13% improvement in unhealthy areas between 2022 and 2025.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain modeling tasks.
• Geographic scope is limited to a single Eucalyptus population in South Australia.
