Spectral Reflectance Data for Quaking Aspen Clones in Colorado

Spectral reflectance measurements for quaking aspen trees include hyperspectral leaf and bark data from a handheld spectrometer and multispectral canopy data from airborne imaging. The dataset contains georeferenced samples with genotype and ploidy level information determined by DNA microsatellite analysis or flow cytometry. Data were collected at sites near Crested Butte in southwestern Colorado.

Use Cases

• Analyze the relationship between spectral reflectance of leaves and ploidy level to identify genetic traits.
• Compare hyperspectral bark measurements with canopy multispectral data to assess whole-tree spectral signatures.
• Use georeferenced sample locations and genotype data to map the spatial distribution of different aspen clones.
• Train models to predict ploidy level from hyperspectral leaf or bark reflectance patterns.

Strengths

• Includes three distinct spectral measurement types: hyperspectral leaf, hyperspectral bark, and multispectral canopy.
• Samples are georeferenced and have associated genotype/ploidy data from laboratory analysis.
• Data collection combines ground-based handheld spectrometer measurements with airborne imaging from a UAS.

Limitations

• Sample size and row count are unknown, limiting statistical power assessments.
• Geographic scope is limited to sites in southwestern Colorado, reducing generalizability.
• Dataset includes raw imagery which may require specialized tools for processing and analysis.
