Landsat Imagery for Soil Moisture Experiment in Alabama

2003 satellite imagery from Landsat 5 TM and Landsat 7 ETM+ sensors was developed for the Soil Moisture Experiment 2003 (SMEX03) in Alabama. The dataset, provided by the National Aeronautics and Space Administration, is intended for studying land cover features. It is available in BIN, ISO, and HTML file formats.

Use Cases

• Analyzing land cover classification using multispectral bands from Landsat sensors.
• Correlating satellite-derived reflectance with in-situ soil moisture measurements from SMEX03.
• Studying surface features in the visible and infrared wavelengths for environmental modeling.
• Providing geospatial baseline data for the Alabama region during the summer of 2003.

Strengths

• Data is sourced from established Landsat 5 and Landsat 7 satellite platforms, ensuring calibrated sensor data.
• Imagery is specifically tied to a defined field campaign (SMEX03), providing context for validation.

Limitations

• Core metadata such as column names, row count, and exact spatial resolution are unavailable from all sources.
• A significant conflict exists in the 'last updated' date between platforms (2003 vs. 2026), casting doubt on metadata maintenance.
