Tallgrass Prairie Hyperspectral Imagery with 323 Bands

Airborne Hyperspectral Reflectance data from The Nature Conservancy’s Tallgrass Prairie Preserve in Oklahoma. The dataset contains orthorectified flight lines with 323 spectral bands across 400-2450 nm, collected over three days in 2020, 2021, and 2022. Data were captured by Oklahoma State University using an AisaFENIX 1K sensor mounted on a fixed-wing aircraft.

Use Cases

• Developing spectral indices for plant species classification across 323 bands.
• Analyzing temporal changes in prairie vegetation using data from three separate years (2020-2022).
• Training models for biodiversity mapping at a 1-meter spatial resolution.
• Validating satellite-derived vegetation products with high-fidelity airborne reflectance data.

Strengths

• High spectral detail with 323 individually corrected bands.
• Data are radiometrically, geometrically, and atmospherically corrected for analysis readiness.
• Multi-temporal coverage from three distinct collection dates across 2020-2022.

Limitations

• Exact spatial extent, row count, and file size are unspecified across all sources.
• License information is conflicting: one source lists 'other-license-specified' while others list none.
• Column names and data structure within the BIN files are not described.
