MASTER Airborne Multispectral Imagery of Oregon and Wyoming

MASTER instrument Level 1B data products provide georeferenced multispectral imagery from two airborne flights over Oregon and Wyoming in August 2006. The dataset contains calibrated radiance data across 50 spectral bands, from visible to thermal infrared wavelengths, at approximately 10-meter spatial resolution. It is produced by the National Aeronautics and Space Administration and includes ancillary flight information and browse images.

Use Cases

• Analyzing land surface temperature and thermal properties using calibrated radiance data from thermal infrared bands.
• Mapping vegetation health or geological features by examining spectral reflectance across visible and near-infrared wavelengths.
• Conducting sensor comparison or calibration studies by utilizing detailed instrument configuration and band information.
• Visualizing flight paths and spatial coverage for mission planning or data context using provided georeferenced imagery and flight summaries.

Strengths

• Contains data from 50 distinct spectral bands covering a wide wavelength range from 0.460 to 12.879 micrometers.
• Provides high spatial resolution imagery at approximately 10 meters per pixel from airborne collection.
• Includes extensive ancillary data such as flight paths, instrument configuration, and summary information for context.

Limitations

• Core data files are in the legacy HDF-4 format, which may require specialized tools for access and processing.
• Conflicting last updated dates exist between sources (2006-08-03 on NASA Earthdata vs. 2026-03 13 on Data.gov).
• Specific row counts, file sizes, and detailed column names are not provided across any platform.
