CN_Wheat10: China's 10 m spring-winter wheat maps from time series remote sensing (2018-2024)

This dataset is "China Wheat Annual Distribution Product (CN-Wheat10)", which contains three types of remote sensing mapping results: spring wheat harvested maps, winter wheat harvested maps, and winter wheat planted maps, covering the years 2018 to 2024 across major wheat-growing regions in China.Each data file is named according to the following convention: CN-Wheat10_Year_WheatType_GrowthStage.tifWheat Type:SW: Spring WheatWW: Winter WheatGrowth Stage:P: Planted StageH: Harvested StageFor example, the file “CN-Wheat10_2018_SW_H.tif” represents the harvested area map of spring wheat in 2018.All datasets are provided in GeoTIFF format with a spatial reference system of WGS84 (EPSG:4326). The products are generated using Sentinel-1 and Sentinel-2 multi-source satellite data, incorporating both spectral and phenological features, combined with machine learning techniques. The spatial resolution is 10 meters, and the maps are available annually.

本数据集为「中国小麦年度分布产品（CN-Wheat10）」，包含三类遥感制图成果：春小麦收获分布图、冬小麦收获分布图与冬小麦种植分布图，覆盖2018至2024年中国主要小麦种植区。各数据文件遵循如下命名规范：CN-Wheat10_年份_小麦类型_生育阶段.tif。其中，小麦类型定义为：SW为春小麦（Spring Wheat），WW为冬小麦（Winter Wheat）；生育阶段定义为：P为种植期（Planted Stage），H为收获期（Harvested Stage）。例如，文件「CN-Wheat10_2018_SW_H.tif」代表2018年春小麦收获面积分布图。所有数据集均采用GeoTIFF格式存储，空间参考系统为WGS84（EPSG:4326）。本产品基于Sentinel-1与Sentinel-2多源卫星数据生成，融合光谱与物候特征，并结合机器学习技术。空间分辨率为10米，产品按年度发布。
