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: <b>spring wheat harvested maps, winter wheat harvested maps, and winter wheat planted maps</b>, covering the years <b>2018 to 2024</b> across major wheat-growing regions in China.Each data file is named according to the following convention:<b> </b><b>CN-Wheat10_Year_WheatType_GrowthStage.tif</b><b>Wheat Type</b>:<code>SW</code>: Spring Wheat<code>WW</code>: Winter Wheat<b>Growth Stage</b>:<code>P</code>: Planted Stage<code>H</code>: Harvested StageFor example, the file “<code>CN-Wheat10_2018_SW_H.tif”</code> represents the <b>harvested area map of spring wheat in 2018</b>.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。所有数据文件均遵循如下命名规范：<b>CN-Wheat10_Year_WheatType_GrowthStage.tif</b>。其中，小麦类型（Wheat Type）：<code>SW</code>代表春小麦（Spring Wheat），<code>WW</code>代表冬小麦（Winter Wheat）；生育阶段（Growth Stage）：<code>P</code>代表种植期（Planted Stage），<code>H</code>代表收获期（Harvested Stage）。例如，文件「<code>CN-Wheat10_2018_SW_H.tif</code>」即代表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）。该产品基于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。数据集空间分辨率为10米，按年度发布。
