四川省1：100万土地利用数据集（2000）

本数据库是四川省2000年1：100万土地利用类型数据集，反映了2000年四川省土地利用状况及其地域分布规律，主要地类包括：城镇、农田、湖泊、河流、草地、林地等，以ESRI Shape格式存储，该数据集均由三期同年陆地卫星TM影像经过人工解译获得。数据源于国家科技部九五科技攻关课题“国家级基本资源与环境遥感动态信息服务体系的建立”以及科学院知识创新工程重大项目“国土环境遥感时空信息分析与数字地球相关理论技术预研究”项目

This database is the 1:1,000,000 scale land use type dataset of Sichuan Province in 2000, which characterizes the land use status and its regional distribution patterns of Sichuan Province in 2000. Its main land use categories include: urban areas, croplands, lakes, rivers, grasslands, woodlands, etc. The dataset is stored in ESRI Shapefile format, and was entirely obtained through manual interpretation of three scenes of Landsat TM images acquired in the same year (2000). The data is derived from the "9th Five-Year Plan" National Key Scientific and Technological Research Project "Establishment of the National Basic Resources and Environmental Remote Sensing Dynamic Information Service System" funded by the Ministry of Science and Technology of the People's Republic of China, as well as the Major Project of the Knowledge Innovation Program of the Chinese Academy of Sciences titled "Spatio-temporal Analysis of Land and Environmental Remote Sensing Information and Preliminary Research on Theoretical Technologies Related to Digital Earth".
