Sign in to view source links and access this dataset
Description
NASA's AVIRIS Project provides attributed geospatial and tabular metadata for flight lines from the AVIRIS-C, AVIRIS-NG, and AVIRIS-3 airborne imaging spectrometers. The dataset includes shapefiles, GeoJSON, KMZ, and CSV files detailing flight dates, coordinates, investigators, and links to associated Level 1B radiance and Level 2A reflectance image files. AVIRIS-3 data specifically contains calibrated radiance and surface reflectance images in netCDF format, measuring reflected light at 7.4-nm intervals across the 390-2500 nm spectral range.
Use Cases
Query and visualize flight line locations for specific campaigns or years based on the provided geospatial metadata.
Analyze surface mineral composition based on the high-resolution spectral reflectance data from AVIRIS-3.
Study atmospheric properties using the calibrated radiance measurements across the visible to shortwave infrared spectrum.
Georeference and orthocorrect airborne imagery using the included observation geometry and geolocation lookup tables.
Strengths
Includes metadata for multiple AVIRIS instrument generations (AVIRIS-C, AVIRIS-NG, AVIRIS-3), suggesting broad temporal coverage.
Provides data in multiple standard geospatial formats (Shapefile, GeoJSON, KMZ, CSV) for interoperability.
AVIRIS-3 spectral data has high resolution, measuring at 7.4-nm intervals across a 390-2500 nm range.
Limitations
Row count and total dataset size are unknown, which may limit suitability assessment for large-scale projects.
Column-level documentation is absent; field semantics must be inferred after download.
Last update date is unknown; freshness unverified.
