中国1：25万土地覆被裸岩类型数据（2005年）

中国1:25万土地覆被裸岩类型数据（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。

China's 1:250,000-scale land cover bare rock type dataset (2005) was developed using multiple geospatial data sources, including China's 1:100,000-scale land use data and its dynamic data, Landsat precisely corrected county-level false-color composite images acquired concurrently with the land use data, China's 1:500,000-scale grassland resource data, 1:1,000,000-scale soil type data, 1:1,000,000-scale vegetation type data, and other relevant datasets. The development was conducted under the software environments of MGE, Arc/Info or ArcGIS, adopting a hybrid approach that combines expert analysis and remote sensing automatic classification, and thematic mapping was performed based on content and regional characteristics to generate the target 1:250,000-scale land cover remote sensing survey and monitoring vector dataset.
