四川省100米分辨率土地覆被城镇建设用地类型数据(2005年)

四川省100米分辨率城镇建设用地空间分布数据集（2005年）为2005年四川省城镇建设用地空间分布。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完成的。

The 100-meter-resolution spatial distribution dataset of urban construction land in Sichuan Province (2005) documents the spatial distribution pattern of urban construction land within Sichuan Province in 2005. Its data sources include China's 1:10 land use data and its dynamic datasets, county-level precisely corrected false-color composite Landsat images synchronized with the land use data, as well as China's 1:500,000 grassland resource data, 1:1,000,000 soil type data and 1:1,000,000 vegetation type data. The dataset was developed under software environments such as MGE, Arc/Info or ArcGIS, using a hybrid approach integrating expert analysis and automated remote sensing classification, and completed through thematic mapping procedures tailored to its content and regional divisions.
