中国100米分辨率土地覆被典型草地类型数据（2005年）

中国100米分辨率土地覆被典型草地类型数据（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 Typical Grassland Type Land Cover Dataset (2005) was developed using multiple data sources, including China's 1:10 scale land use data and its dynamic change data, county-level false-color composite Landsat satellite images that were precisely corrected and 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 dataset was produced under environments such as MGE, Arc/Info, or ArcGIS, via a combination of expert analysis and remote sensing automatic classification methods. First, China's 1:250,000-scale land cover remote sensing survey and monitoring vector data was generated through thematic mapping based on content and regional criteria, and then the final 100m resolution dataset was completed by rasterizing using this vector data as the base map.
