AVIRIS Facility Instruments: Flight Line Metadata and Geospatial Boundaries

NASA provides attributed geospatial and tabular information for identifying flight lines from the AVIRIS-C and AVIRIS-NG airborne imaging spectrometer collections. The dataset includes shapefiles, GeoJSON, and KMZ files for visualization, plus CSV tables with dates, bounding coordinates, site names, investigators, and associated file names for radiance and reflectance data. The data was last updated on 2026-03-13.

Use Cases

• Query and filter flight lines of interest based on dates, site names, and investigators mentioned in the description.
• Visualize flight line locations and coverage areas using GIS software based on the provided shapefiles and GeoJSON.
• Link flight line metadata to corresponding Level 1B (radiance) and Level 2 (reflectance) data files based on the associated file names.
• Analyze the spatial and temporal distribution of data collection campaigns based on bounding coordinates and dates.

Strengths

• Includes data for both AVIRIS-C and AVIRIS-NG instruments across all years of collection.
• Provides multiple geospatial formats (shapefile, GeoJSON, KMZ) for visualization and querying.
• Tabular metadata includes specific attributes like dates, bounding coordinates, site names, and investigator names.

Limitations

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