Le Bureau du géographe des États-Unis fournit l'ensemble de données LSIB (Large Scale International Boundary). Il est dérivé de deux autres ensembles de données : un fichier vectoriel de lignes LSIB et les World Vector Shorelines (WVS) de la National Geospatial-Intelligence Agency (NGA). Les limites intérieures reflètent les règles du gouvernement américain concernant les limites, les litiges frontaliers et la souveraineté. Les limites extérieures sont dérivées du WVS. Toutefois, les données sur le littoral du WVS sont obsolètes et généralement décalées de plusieurs centaines de mètres à plus d'un kilomètre. Chaque entité correspond à la zone polygonale délimitée par les frontières intérieures et les côtes extérieures, le cas échéant. De nombreux pays sont constitués de plusieurs entités, une par région distincte. Chacune des 180 741 entités fait partie de la géométrie de l'un des 284 pays décrits dans cet ensemble de données.

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 The exterior\nboundaries are derived from the WVS; however, the WVS coastline\ndata is outdated and generally shifted from between several hundred\nmeters to over a kilometer.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.
