G-LiHT Hyperspectral Ancillary V001

North American forest communities and ecoregions in the Conterminous United States, Alaska, Puerto Rico, and Mexico are mapped by this airborne imaging system. The dataset provides ancillary information related to aircraft attitude, altitude, view and solar angles, and other reflectance and radiance data. It is produced by NASA's Goddard LiDAR, Hyperspectral, and Thermal Imager (G-LiHT) mission and processed as 1-meter resolution GeoTIFF rasters.

Use Cases

• Calibrate hyperspectral imagery based on provided aircraft attitude and altitude data.
• Model solar radiation and canopy reflectance based on included view and solar angles.
• Analyze forest structure and function across diverse North American ecoregions based on the mission's focus.

Strengths

• Data is collected by NASA's G-LiHT airborne system, a known scientific instrument.
• Spatial resolution is specified as 1 meter over locally defined areas.
• Product includes associated header files for metadata interpretation.

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.
