GFSAD: Global Crop Dominance Map at 1 km Resolution for 2010

A 1-kilometer resolution global map of crop dominance for nominal 2010, created by NASA's MEaSUREs program. The dataset integrates multiple remote sensing sources, climate data, and ground references to classify eight dominant crop types. It is based on data ranging from 2007 through 2012.

Use Cases

• Modeling global food production patterns based on crop dominance classes.
• Analyzing the relationship between climate variables and agricultural land use based on integrated precipitation and temperature data.
• Assessing the distribution of irrigated versus rainfed cropland based on the underlying IWMI map.
• Validating or calibrating other land cover datasets using the multi-source remote sensing inputs.

Strengths

• Integrates multiple authoritative data sources, including AVHRR, SPOT, MODIS, and IWMI cropland maps.
• Provides a consistent global snapshot for a nominal year, based on data from a 2007-2012 time range.
• Classifies eight distinct crop dominance categories at a 1 km spatial resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset has known issues referenced in a separate user guide.
