G-LiHT Trajectory: Aircraft Location and Orientation Data for North American Forests

North American forest communities and ecoregions across the Conterminous United States, Alaska, Puerto Rico, and Mexico are mapped by the G-LiHT airborne imaging system. The GLTRAJECTORY product provides aircraft location and orientation data to support other G-LiHT data products. It is processed as a Google Earth overlay KML file and provided by NASA's Goddard Space Flight Center.

Use Cases

• Georeferencing and aligning other G-LiHT data products based on the provided aircraft location and orientation.
• Visualizing and analyzing flight path coverage for airborne surveys over North American forests.
• Supporting ecosystem structure and function studies by providing the spatial context for multi-sensor imagery.

Strengths

• Data originates from NASA's Goddard Space Flight Center, a highly authoritative source.
• Covers a broad diversity of forest communities across multiple North American regions.
• Provides data in a Google Earth KML format for immediate visualization.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
