GFSAD30SEACE: Cropland Extent Map for Southeast and Northeast Asia, 2015, 30m Resolution

NASA's MEaSUREs program produced this 30-meter resolution cropland extent map for Southeast and Northeast Asia for the nominal year 2015. The data product, GFSAD30SEACE, was generated using the Random Forest classifier on Landsat 8 OLI, Landsat 7 ETM+, and SRTM elevation data. It provides a critical baseline for agricultural studies related to water sustainability and global food security.

Use Cases

• Modeling water sustainability for agriculture based on cropland extent and location.
• Analyzing land use change and agricultural expansion patterns over time.
• Establishing baseline data for food security assessments and policy-making.
• Training machine learning models for land cover classification using satellite and elevation data.

Strengths

• Data is produced by NASA's MEaSUREs program, indicating a high level of scientific rigor.
• Provides 30-meter spatial resolution, offering detailed land cover classification.
• Integrates multiple data sources: Landsat 8 OLI, Landsat 7 ETM+, and SRTM elevation data.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Certain small Pacific islands are not classified, creating spatial gaps in the dataset.
• Column-level documentation is absent; field semantics must be inferred after download.
