GFSAD: Cropland Extent for North America at 30m Resolution, 2010

2010 cropland extent data for North America at 30-meter resolution, produced by NASA's MEaSUREs program. The product uses a combination of Random Forest and RHSEG classifiers on Landsat 5 TM, Landsat 7 ETM+, and SRTM elevation data. It defines areas of cropland, non-cropland, and water bodies over 10° by 10° tiles.

Use Cases

• Baseline mapping for agricultural studies based on the cropland extent layer.
• Policy analysis for food security based on the 30-meter resolution land cover data.
• Water sustainability modeling based on the classification of cropland and water bodies.
• Land use change detection based on the 2010 nominal year snapshot.

Strengths

• 30-meter spatial resolution provides detailed land cover information.
• Data derived from authoritative sources: Landsat satellite imagery and SRTM elevation data.
• Uses a combination of pixel-based (Random Forest) and object-oriented (RHSEG) classifiers.

Limitations

• Known issues, constraints, and limitations are documented separately in the ATBD (page 39).
• Column-level documentation is absent; field semantics must be inferred after download.
