Global Food Security-support Analysis Data (GFSAD) Cropland Extent 2015 Europe, Central As

Europe, Central Asia, Russia, and the Middle East are covered by this NASA-produced cropland extent map for the nominal year 2015. The data product was generated using a pixel-based supervised random forest algorithm applied to Landsat 7 ETM+, Landsat 8 OLI, and SRTM elevation data. It provides a 30-meter resolution classification of cropland, non-cropland, and water bodies over 10° by 10° tiles.

Use Cases

• Baseline mapping for agricultural policy and food security studies based on the cropland extent classification.
• Analysis of land use change over time when combined with other temporal data, based on the 2015 nominal year.
• Integration with hydrological models based on the inclusion of water body classification.
• Validation of other land cover products based on the 30-meter resolution derived from Landsat and SRTM data.

Strengths

• Data is produced by NASA under the MEaSUREs program, indicating authoritative sourcing.
• Provides 30-meter spatial resolution, offering detailed land cover classification.
• Covers a broad geographic region including Europe, Central Asia, Russia, and the Middle East.
• Uses a supervised random forest machine learning algorithm for classification, a documented methodology.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Known issues and constraints are referenced in a separate document (ATBD page 20), requiring additional review.
• Row count is unknown, which may limit suitability assessment for large-scale computational tasks.
