Airborne Hyperspectral Ancillary Data for Forest Ecosystems

Airborne imaging data from the G-LiHT mission provides information on aircraft attitude, altitude, and view angles. The data is processed as GeoTIFF rasters at 1-meter spatial resolution for local areas across North America. It is produced by NASA's Goddard Space Flight Center.

Use Cases

• Calibrating hyperspectral reflectance using ancillary radiance data fields.
• Modeling forest canopy structure by integrating altitude and view angle information.
• Correcting for aircraft attitude variations in time-series aerial imagery analysis.
• Mapping solar illumination conditions for ecological studies across diverse forest communities.

Strengths

• 1-meter spatial resolution enables detailed local analysis.
• Covers a broad diversity of forest communities and ecoregions in North America.

Limitations

• Spatial coverage is limited to locally defined airborne swaths, not continuous.
• Specific temporal coverage and total data volume are not provided.
