中国1:25万面积1km2以上湖泊数据集（2005-2006年）

该数据集基于cbers及TM遥感影像，结合地形图、网络地图及中国湖泊志等资料，对面积大于1km2以上的湖泊进行遥感解译，并完善湖泊所属行政区、湖区、湖泊性质及所属流域等指标信息，形成了完整可靠的全国范围的湖泊空间分布数据。
包含了1个文件，为shp矢量数据，“全国1以上湖泊rec.shp”。

This dataset is developed using CBERS and TM remote sensing imagery, integrated with topographic maps, web maps, *Chinese Lake Records* and other reference materials. Remote sensing interpretation was performed on all lakes with an area exceeding 1 km², and indicator information including the administrative divisions each lake belongs to, lake regions, lake properties and their affiliated river basins was supplemented and refined. As a result, a complete and reliable spatial distribution dataset of lakes across the entire country was established. The dataset contains one single file, which is a shapefile (SHP) vector data file named "National_Lakes_Over_1km2_Rec.shp".
