Landsat 7 ETM+ Orthorectified Scenes Over ESA Ground Stations

Landsat 7 Enhanced Thematic Mapper orthorectified Level 1 imagery for Kiruna, Maspalomas, Matera, and Neustrelitz visibility masks. Each scene covers approximately 185 by 170 kilometers, with individual spectral bands requiring 50MB and the panchromatic band requiring 200MB. The dataset was provided by the European Space Agency and last updated in 2003.

Use Cases

• Analyze land cover changes using the 30-meter resolution spectral bands (Bands 1-7) over the four ESA ground station areas.
• Fuse high-resolution 15-meter panchromatic Band 8 data with multispectral bands for enhanced visual interpretation.
• Perform orthorectification validation by examining the Level 1T and Level 1Gt product quality across different geographic regions.
• Study seasonal variations by comparing scenes captured under the visibility masks of the specified ground stations.

Strengths

• Provides high-quality orthorectified Level 1 products (L1T/L1Gt) for analysis.
• Includes the high-resolution 15-meter panchromatic band (Band 8) alongside standard 30-meter spectral bands.
• Covers four distinct geographic areas via ESA ground station visibility masks.

Limitations

• Data is temporally stale, with a last update recorded in December 2003.
• Specific row counts, total size, and complete temporal coverage are unknown.
• Limited geographic coverage to areas within visibility of four specific ESA ground stations.
