中国1：25万土地覆被近海湿地类型数据（1980s）

中国1:25万土地覆被近海湿地类型数据（1980s），是以中国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生成中国1:25万土地覆盖遥感调查与监测矢量数据。

China's 1:250,000 Land Cover and Coastal Wetland Type Dataset (1980s) was developed using multiple data sources, including China's 1:100,000 Land Use Data and its dynamic datasets, county-level precisely corrected false-color composite Landsat images collected in the same period as the land use data, 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 generated under the working environments of MGE, Arc/Info or ArcGIS, through a hybrid methodology combining expert analysis and automated remote sensing classification, via thematic mapping based on content and regional characteristics, to produce the 1:250,000 vector dataset for China's land cover remote sensing survey and monitoring.
