重庆市100米分辨率土地覆被裸岩类型数据(1980年代)

重庆市100米分辨率裸岩空间分布数据集（1980年代）为1980年代重庆市裸岩空间分布。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 bare rocks in Chongqing (1980s) documents the spatial distribution of bare rocks across Chongqing during the 1980s. The dataset was developed using multiple data sources including China's 1:10 scale land use data and its dynamic data, county-level false-color composite images of Landsat satellites 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. It was compiled under GIS environments such as MGE, Arc/Info or ArcGIS, through a hybrid approach combining expert analysis and automated remote sensing classification, utilizing thematic mapping methods based on thematic content and regional characteristics.
