中国100米分辨率土地覆被水田类型数据（2005年）

中国100米分辨率土地覆被水田类型数据（2005年），是以中国1:10土地利用数据及其动态数据、与土地利用数据同期陆地卫星精纠正分县假彩色合成影像以及中国1:50万草地资源数据、1:100万土壤类型数据和1:100万植被类型数据等为数据源，在MGE和Arc/info或ArcGIS等环境下，通过专家分析和遥感自动分类相结合的方法，按照内容和区域，采用专题制图的方式生成中国1:25万土地覆盖遥感调查与监测矢量数据，再以此矢量数据为底图栅格化完成的。

China 100m-resolution paddy field type land cover dataset (2005) was constructed using multiple data sources, including China's 1:10 scale land use data and its dynamic change data, county-level precisely corrected false-color composite Landsat images synchronized with the land use data, China's 1:500,000-scale grassland resource data, 1:1,000,000-scale soil type data, and 1:1,000,000-scale vegetation type data. The processing was carried out under software environments such as MGE, Arc/Info or ArcGIS, adopting a combined methodology of expert analysis and remote sensing automatic classification. Firstly, 1:250,000-scale vector data for China's land cover remote sensing survey and monitoring was generated via thematic mapping based on content categories and regional divisions. Finally, the target dataset was completed by rasterizing this vector dataset as the base map.
