青海盐湖空间分布数据集（2020）

本数据集包括2020年青海盐湖分布数据。这些数据通过Landsat卫星遥感影像人工解译提取盐湖图斑，矢量化处理后形成。数据集以光盘、硬盘、服务器等多种方式存储，光盘、硬盘存储的数据结构类型为SHP格式保存（ArcGIS9.X-10.5），服务器存储采用Orcale数据库。主要包含盐湖名称(name)、编码(BM)、面积(Area)等信息。数据集共有54条记录，512KB。

This dataset contains distribution data of salt lakes in Qinghai Province, China, in 2020. The data was extracted as salt lake patches through manual interpretation of Landsat satellite remote sensing imagery, and then processed via vectorization. The dataset is stored through multiple mediums including optical discs, hard disk drives and servers. Data stored on optical discs and hard disks is saved in SHP format (compatible with ArcGIS 9.X-10.5), while data stored on servers is managed using an Oracle database. It mainly includes information such as salt lake name (name), code (BM), area (Area), and other relevant details. The dataset contains a total of 54 records with a size of 512 KB.
