G-LiHT Hyperspectral Radiance: Forest Ecosystem Imagery at 1-Meter Resolution

G-LiHT Hyperspectral Radiance V001 is an airborne imaging dataset from NASA's Goddard LiDAR, Hyperspectral, and Thermal Imager mission. It provides high-resolution radiance data across 114 spectral bands from 418 to 920 nanometers, processed as 1-meter resolution GeoTIFF rasters. The data focuses on mapping forest communities and ecoregions across North America.

Use Cases

• Classifying forest types and species based on hyperspectral radiance signatures.
• Modeling ecosystem function and health using spectral reflectance data.
• Developing algorithms for BRDF correction and atmospheric compensation in airborne imagery.
• Fusing hyperspectral data with LiDAR and thermal information for multi-modal ecosystem analysis.

Strengths

• Data is collected at a high spatial resolution of 1 meter.
• Covers 114 spectral bands across a wavelength range of 418 to 920 nanometers.
• Processed with corrections for cross-track illumination and BRDF effects.
• Flown at a nominal height of 335 m AGL for close surface approximation.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to its focus on North American forests.
