SAFARI 2000 Tandem Satellite Imagery Pair for Kruger National Park

NASA's EO-1 satellite captured a tandem pair of Advanced Land Imager (ALI) and Landsat ETM+ scenes over Kruger National Park, South Africa, on May 30, 2001. This dataset was created to validate the new ALI sensor technology against the established ETM+ instrument. It includes multispectral band files, metadata, and calibration parameters for direct comparison.

Use Cases

• Comparing sensor performance by analyzing reflectance values across matching shortwave infrared, near infrared, and visible bands.
• Assessing vegetation density and land cover classification in a savanna environment using false color composites.
• Validating atmospheric correction and calibration algorithms using the provided calibration parameter file and metadata.
• Studying land surface radiative properties with coincident satellite and ground-based SAFARI 2000 campaign measurements.

Strengths

• Provides a direct, near-simultaneous (one-minute apart) comparison between a new technology (ALI) and a proven benchmark (Landsat ETM+).
• Includes ground-truth data from several SAFARI 2000 field campaigns conducted in the same Kruger National Park area.
• Contains detailed metadata documenting path/row, sample/line counts, band file names, and sun angles for precise analysis.

Limitations

• The dataset is a single snapshot from May 30, 2001, offering no temporal series for change detection.
• Specific row counts, column names, and dataset size are not provided by any source.
• There is a conflict in the 'last updated' metadata, with one source listing 2001 and another listing 2026.
