Major Tom: Expandable Sentinel-1 and Sentinel-2 Earth Observation Data

ESA-PhiLab developed Major Tom as an expandable framework for Earth Observation, integrating Sentinel-1 and Sentinel-2 satellite imagery. Updated in February 2026, it provides a foundation for multi-spectral and remote sensing analysis despite currently undocumented record counts.

Use Cases

• Land cover classification using Sentinel-2 multi-spectral bands
• Surface change detection using Sentinel-1 radar imagery
• Vegetation health monitoring via Sentinel-2 spectral indices

Strengths

• Integrates both Sentinel-1 and Sentinel-2 data sources
• Maintained by ESA-PhiLab
• Apache-2.0 license allows for commercial and research use

Limitations

• Specific record counts and file sizes are not documented in the metadata
• Lack of explicit column definitions or schema details
