Northeast China Maize Growth Stages from 2001 to 2024 at 500-Meter Resolution

Eight critical maize phenology stages—Emerged, three-leaf, seven-leaf, jointing, flowering, silking, dough, and mature—are mapped for Northeast China from 2001 to 2024. This 500-meter resolution dataset is georeferenced in the WGS 1984 coordinate system and was authored by Huizhu Wu. The 85.2 MB resource was last updated on April 27, 2026.

Use Cases

• Modeling crop yield based on observed phenology stages and temporal coverage from 2001 to 2024
• Monitoring agricultural land use and crop health in Northeast China based on the 500-meter spatial resolution
• Analyzing the impact of climate variability on maize cultivation timing based on the eight defined growth stages
• Calibrating remote sensing algorithms for crop classification using the georeferenced phenology data

Strengths

• Covers a 24-year time range from 2001 to 2024
• Includes eight defined maize growth stages
• Provides data at a 500-meter spatial resolution
• Georeferenced in the WGS 1984 coordinate system

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the Northeast China region
