中国2米分辨率农田数据产品(2020年)

该数据集基于Mapbox和Google卫星影像，设计三阶段框架：覆盖评估、高效采样、多模验证，最终生成2米分辨率CropLayer。研究采用像素、格网、区域三级验证体系，确保了不同空间尺度下精度结果的可靠性与可解释性。该数据产品能够清晰呈现我国农田边界、地块形态及微地形特征，尤其适用于小块农田、丘陵山区等复杂地形，以Shapefile矢量格式存储。本次数据共享覆盖32个省级单位（包含自治区、直辖市、台湾地区，不包含香港、澳门），每个省的数据包里按县级行政单元独立成文件，便于按区域调用和分析。This dataset is built upon Mapbox and Google satellite imagery, with a three-stage workflow consisting of coverage assessment, efficient sampling, and multi-modal verification, finally yielding a 2-meter resolution CropLayer. The research adopts a three-tier verification system across pixel, grid and regional scales, ensuring the reliability and interpretability of accuracy outcomes across various spatial scales. This data product clearly depicts China's farmland boundaries, plot configurations and micro-topographic characteristics, and is particularly suitable for complex terrains such as small-scale farmlands, hilly and mountainous areas, and is stored in Shapefile vector format. This data sharing initiative covers 32 provincial-level administrative units (including autonomous regions, municipalities directly under the Central Government, and the Taiwan region, excluding Hong Kong and Macao). Each provincial data package is split into independent files by county-level administrative divisions, facilitating regional-based calling and analysis.
