미국 지리학자 사무소에서는 대규모 국제 경계 (LSIB) 데이터 세트를 제공합니다. 이 데이터는 LSIB 선 벡터 파일과 National Geospatial-Intelligence Agency (NGA)의 World Vector Shorelines (WVS)라는 두 가지 다른 데이터 세트에서 파생됩니다. 내부 경계는 경계, 경계 분쟁, 주권에 관한 미국 정부 정책을 반영합니다. 외부 경계는 WVS에서 파생되지만 WVS 해안선 데이터는 오래되었으며 일반적으로 수백 미터에서 1km 이상 이동합니다. 각 특징은 내부 경계와 외부 해안선으로 둘러싸인 다각형 영역이며, 많은 국가가 불연속 영역당 하나씩 여러 특징으로 구성됩니다. 180,741개의 각 지형지물은 이 데이터 세트에 설명된 284개 국가 중 하나의 지오메트리 일부입니다.

It is derived\nfrom two other datasets: a LSIB line vector file and the World\nVector Shorelines (WVS) from the National Geospatial-Intelligence\nAgency (NGA). The interior boundaries reflect U.S. government policies\non boundaries, boundary disputes, and sovereignty. The exterior\nboundaries are derived from the WVS; however, the WVS coastline\ndata is outdated and generally shifted from between several hundred\nmeters to over a kilometer. Each feature is the polygonal area\nenclosed by interior boundaries and exterior coastlines where applicable,\nand many countries consist of multiple features, one per disjoint\nregion. Each of the 180,741 features is a part of the geometry\nof one of the 284 countries described in this dataset.\n\n### Table Schema\n\n**Table Schema**\n\n| Name | Type | Description |\n|------------|--------|----------------------------|\n| OBJECTID | STRING | Object ID |\n| COUNTRY_NA | STRING | US-recognized country name |\n\n### Terms of Use\n\n**Terms of Use**\n\nThere are no restrictions on use of this US public domain data.\n\n### Explore with Earth Engine\n\n| **Important:** Earth Engine is a platform for petabyte-scale scientific analysis and visualization of geospatial datasets, both for public benefit and for business and government users.
