SMEX03 Land Use Classification Data for Oklahoma

NSIDCV0 provides land use classification data derived from Landsat 5 satellite imagery for the Soil Moisture Experiment 2003 (SMEX03). The dataset is focused on the Oklahoma study region. It was created for the 2003 experiment, with metadata updates recorded as recently as 2026.

Use Cases

• Validating soil moisture retrieval algorithms against land cover types.
• Analyzing the correlation between land use categories and in-situ soil moisture measurements from SMEX03.
• Providing a land cover baseline for hydrological modeling in the Oklahoma study area.
• Assessing changes in agricultural or natural land cover for the 2003 experiment period.

Strengths

• Data is derived from the well-calibrated Landsat 5 Thematic Mapper sensor.
• Specifically created for a major, peer-reviewed soil moisture field experiment (SMEX03).
• Has a long-term metadata record, with entries spanning from 2003 to 2026.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source.
• Sources conflict on the license, with one specifying 'other-license-specified' and another listing 'None'.
• The core data is from 2003, which may limit analysis of recent land cover changes.
