SMEX03 Landsat NDVI and NDWI Data for Oklahoma

SMEX03 Landsat Thematic Mapper NDVI and NDWI: Oklahoma, Version 1 provides vegetation and water index data derived from Landsat 5 TM imagery. The dataset was created by the NSIDCV0 organization for the Soil Moisture Experiment 2003 (SMEX03) to study land cover features. It is available across multiple platforms, including NASA EarthData and Data.gov.

Use Cases

• Analyzing vegetation health and density in Oklahoma using NDVI values.
• Monitoring surface water presence and moisture stress via NDWI calculations.
• Supporting land cover classification studies for the SMEX03 experiment period.
• Calibrating or validating soil moisture models with satellite-derived indices.

Strengths

• Data originates from a controlled scientific experiment (SMEX03), ensuring focused application.
• Cross-platform presence on NASA EarthData and Data.gov indicates established credibility.
• Derived from Landsat 5 Thematic Mapper, a well-characterized satellite sensor.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source.
• Sources conflict on the last updated date (2003-07-10 vs. 2026-03 12), creating uncertainty about metadata maintenance.
• The exact license terms are unclear, listed as 'other-license-specified' or 'None'.
