海南省100米分辨率土地覆被裸地类型数据(1980年代)

海南省100米分辨率裸地空间分布数据集（1980年代）为1980年代海南省裸地空间分布。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 bare land in Hainan Province (1980s) depicts the spatial distribution of bare land across Hainan Province during the 1980s. The dataset draws on multiple data sources, including China's 1:100,000-scale land use dataset and its dynamic update data, county-level precisely corrected false-color composite Landsat images acquired in the same period as the land use dataset, China's 1:500,000-scale grassland resource dataset, 1:1,000,000-scale soil type dataset, and 1:1,000,000-scale vegetation type dataset, among others. It was developed through thematic mapping based on thematic content and regional zoning, adopting a combined methodology of expert analysis and automated remote sensing classification within the software environments of MGE, Arc/Info or ArcGIS.
