SMEX03 Landsat Imagery for Oklahoma Land Cover Study

SMEX03 Landsat Thematic Mapper Imagery provides Landsat 5 TM and Landsat 7 ETM+ data for analyzing land cover features during the Soil Moisture Experiment 2003 in Oklahoma. The dataset was produced by the National Aeronautics and Space Administration. Imagery was collected and processed around the SMEX03 campaign period in 2003.

Use Cases

• Studying land cover classification using multispectral imagery from TM and ETM+ sensors.
• Analyzing surface reflectance in visible and infrared wavelengths for soil moisture research.
• Providing geospatial context for field measurements taken during the SMEX03 campaign.
• Comparing land surface conditions in Oklahoma during the 2003 experiment period.

Strengths

• Data is sourced from established Landsat 5 and Landsat 7 satellite sensors, providing standardized spectral bands.
• Dataset is hosted on multiple government platforms (Data.gov and NASA Earthdata), indicating institutional curation.
• Imagery is specifically tied to a well-documented field campaign (Soil Moisture Experiment 2003).

Limitations

• Core metadata conflicts: last update date is listed as both 2003-07-10 and 2026-03-12 across sources.
• Key technical details are missing, including image count, spatial resolution, and specific column/band descriptions.
• License is ambiguously listed as 'other-license-specified' without clear terms.
