The detailed\nversion (2013) is derived from two other datasets: a LSIB line\nvector file and the World Vector Shorelines (WVS) from the National\nGeospatial-Intelligence Agency (NGA). The interior boundaries\nreflect U.S. government policies on boundaries, boundary disputes,\nand sovereignty. The exterior boundaries are derived from the\nWVS; however, the WVS coastline data is outdated and generally\nshifted from between several hundred meters to over a kilometer.\nEach feature is the polygonal area enclosed by interior boundaries\nand exterior coastlines where applicable, and many countries\nconsist of multiple features, one per disjoint region.\n\nCompared with the detailed LSIB, in this simplified dataset some disjointed\nregions of each country have been reduced to a single feature.\nFurthermore, it excludes medium and smaller islands. The resulting\nsimplified boundary lines are rarely shifted by more than 100\nmeters from the detailed LSIB lines. Each of the 312 features\nis a part of the geometry of one of the 284 countries described\nin this dataset.\n\n### Table Schema\n\n**Table Schema**\n\n| Name | Type | Description |\n|------------|--------|------------------------------------------------------------------------------------------|\n| abbreviati | STRING | Country abbreviation |\n| country_co | STRING | [Two-letter FIPS country code](https://en.wikipedia.org/wiki/List_of_FIPS_country_codes) |\n| country_na | STRING | US-recognized country name |\n| wld_rgn | STRING | Continental region, e.g. South America |\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.
