MASTER Airborne Multispectral Imagery for Geological Mapping

Level 1B data products from the MODIS/ASTER Airborne Simulator instrument collected during two flights over Colorado and Utah on July 1, 2004. The dataset contains georeferenced multispectral imagery of calibrated radiance across 50 spectral bands, from visible to thermal infrared wavelengths, at approximately 10-meter spatial resolution. This deployment was coordinated by the U.S. Department of Energy's Remote Sensing Laboratory for mapping geological substrates and mineral content.

Use Cases

• Mapping geological substrates and mineral content using calibrated radiance values from 50 spectral bands.
• Validating satellite-derived spectral indices with high-resolution (10m) airborne imagery.
• Analyzing surface thermal properties using data from the thermal infrared wavelength bands.
• Studying flight paths and instrument configuration for airborne remote sensing mission planning.

Strengths

• Provides calibrated radiance data across 50 spectral bands, offering detailed spectral information.
• Features high spatial resolution of approximately 10 meters for detailed surface analysis.
• Includes ancillary data such as flight paths, instrument configuration, and browse images for context.

Limitations

• Spatial and temporal coverage is limited to two flights on a single day (2004-07-01) over specific areas.
• Conflicting last updated dates exist between platforms (2004-07-01 vs. 2026-03-13), indicating potential metadata inconsistency.
• Specific row counts, file sizes, and detailed column names are not provided by any source.
