Northeast China Corn Phenology 500-meter Dataset

This dataset provides detailed maize phenology data for Northeast China from 2001 to 2024. It features eight critical growth stages—Emerged, three-leaf, seven-leaf, jointing, flowering, silking, dough, and mature—mapped at a 500-meter resolution. The data is georeferenced in the WGS 1984 geographic coordinate system, offering a valuable resource for studying crop growth patterns, agricultural monitoring, and climate change impacts on maize cultivation in the region.本数据集提供了2001年至2024年中国东北地区的精细化玉米物候数据。其涵盖8个关键生育阶段：出苗期、三叶期、七叶期、拔节期、开花期、吐丝期、蜡熟期及完熟期，空间分辨率为500米。该数据采用WGS 1984（World Geodetic System 1984）地理坐标系进行地理配准，可为该区域作物生长规律研究、农业监测以及气候变化对玉米种植的影响评估提供重要支撑。
