Airborne Imaging System Flight Trajectory Data for North American Forests

G-LiHT Trajectory Data provides aircraft location and orientation information for the G-LiHT airborne imaging system. The data supports mapping of forest composition, structure, and function across North America, including the Conterminous United States, Alaska, Puerto Rico, and Mexico. This dataset is processed by LPCLOUD as a Google Earth overlay KML file for entire flight paths.

Use Cases

• Align LiDAR point clouds and hyperspectral imagery using precise aircraft location and orientation data.
• Visualize and analyze flight path extents over North American forests using the provided KML overlay.
• Supplement analysis of forest structure and function by correlating trajectory data with other G-LiHT sensor products.

Strengths

• Covers a broad diversity of forest communities and ecoregions across multiple regions.
• Provides both a detailed KML overlay and a low-resolution browse image for flight path visualization.

Limitations

• Specific row counts, column details, and file sizes are not provided.
• The dataset's temporal coverage and update recency are unknown.
