天津市100米分辨率土地覆被城镇建设用地类型数据(1980年代)

天津市100米分辨率城镇建设用地空间分布数据集（1980年代）为1980年代天津市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 Tianjin (1980s) depicts the spatial distribution pattern of urban construction land in Tianjin during the 1980s. Its data sources include 1:100,000-scale land use data of China and its dynamic data, county-wise precision-corrected false-color composite Landsat images synchronized with the land use data, 1:500,000-scale grassland resource data of China, 1:1,000,000-scale soil type data, and 1:1,000,000-scale vegetation type data, among others. The dataset was developed under environments such as MGE, Arc/Info or ArcGIS, through a combination of expert analysis and automated remote sensing classification, and finalized via thematic mapping based on content and regional divisions.
