Google Earth Engine——2017细节版本美国地理学家办公室提供大尺度国际边界（LSIB）数据集。

LSIB 2017: Large Scale International Boundary Polygons, Detailed

The United States Office of the Geographer provides the Large Scale International Boundary (LSIB) dataset. It is derived from two other datasets: a LSIB line vector file and the World Vector Shorelines (WVS) from the National Geospatial-Intelligence Agency (NGA). The interior boundaries reflect U.S. government policies on boundaries, boundary disputes, and sovereignty. The exterior boundaries are derived from the WVS; however, the WVS coastline data is outdated and generally shifted from between several hundred meters to over a kilometer. Each feature is the polygonal area enclosed by interior boundaries and exterior coastlines where applicable, and many countries consist of multiple features, one per disjoint region. Each of the 180,741 features is a part of the geometry of one of the 284 countries described in this dataset.

美国地理学家办公室提供大尺度国际边界（LSIB）数据集。它来自另外两个数据集：LSIB线状矢量文件和国家地理空间情报局（NGA）的世界矢量海岸线（WVS）。内部边界反映了美国政府关于边界、边界争端和主权的政策。外部边界来自于WVS；然而，WVS的海岸线数据已经过时，一般在几百米到一公里以上的范围内变动。每个特征是由内部边界和外部海岸线（如适用）所包围的多边形区域，许多国家由多个特征组成，每个不相连的区域有一个。180,741个特征中的每一个都是本数据集中描述的284个国家中的一个国家的几何形状的一部分。
