G-LiHT: Airborne Hyperspectral Reflectance Data at 1-Meter Resolution

G-LiHT's Hyperspectral Reflectance data product provides high-resolution reflectance data across 114 spectral ranges from 418 to 920 nanometers. The data is collected by NASA's airborne imaging system at a nominal height of 335 meters above ground level, covering forest communities and ecoregions in North America, including the Conterminous United States, Alaska, Puerto Rico, and Mexico. The data is processed as a 1-meter spatial resolution raster product.

Use Cases

• Classifying forest species and health based on hyperspectral reflectance signatures.
• Modeling ecosystem function and structure using surface reflectance approximations.
• Mapping land surface radiative properties across diverse North American ecoregions.
• Developing spectral indices for vegetation analysis using 114-band data.

Strengths

• Provides data across 114 spectral ranges from 418 to 920 nanometers.
• Offers high spatial resolution at 1 meter per pixel.
• Data is corrected for cross-track illumination and BRDF effects.
• Coverage includes a broad diversity of forest communities across North America.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the airborne collection areas.
