As camadas de unidades administrativas globais (GAUL, na sigla em inglês) compilam e divulgam as melhores informações disponíveis sobre unidades administrativas de todos os países do mundo, contribuindo para a padronização do conjunto de dados espaciais que representa essas unidades. A GAUL sempre mantém camadas globais com um sistema de codificação unificado nos níveis de país, primeiro (por exemplo, departamentos) e segundo administrativo (por exemplo, distritos). Quando os dados estão disponíveis, eles fornecem camadas de país por país até o terceiro, quarto e níveis mais baixos. A metodologia geral consiste em: a) coletar os melhores dados disponíveis das fontes mais confiáveis; b) estabelecer períodos de validação dos recursos geográficos (quando possível); c) adicionar dados selecionados à camada global com base no último mapa de fronteiras de países fornecido pela Unidade Cartográfica da ONU (UNCS); d) gerar códigos usando o sistema de codificação GAUL; e) distribuir dados aos usuários (consulte Aspectos técnicos do conjunto de distribuição GAUL).
Algumas unidades administrativas são recursos multipoligônicos.

The GAUL always maintains global\nlayers with a unified coding system at country, first (e.g. departments),\nand second administrative levels (e.g. districts). Where data is available,\nit provides layers on a country by country basis down to third, fourth, and\nlowers levels. The overall methodology consists in a) collecting the best\navailable data from most reliable sources, b) establishing validation\nperiods of the geographic features (when possible), c) adding selected data\nto the global layer based on the last country boundaries map provided by\nthe UN Cartographic Unit (UNCS), d) generating codes using GAUL Coding\nSystem, and e) distribute data to the users\n(see [Technical Aspects of the GAUL Distribution Set](https://data.apps.fao.org:/map/catalog/srv/api/records/9c35ba10-5649-41c8-bdfc-eb78e9e65654/attachments/GAUL2015_Documentation.zip).\nNote that some administrative units are multipolygon features.\n\n### Table Schema\n\n**Table Schema**\n\n| Name | Type | Description |\n|------------|--------|------------------------------------------|\n| ADM0_CODE | INT | GAUL country code |\n| ADM0_NAME | STRING | UN country name |\n| DISP_AREA | STRING | Unsettled territory: 'Yes' or 'No' |\n| STATUS | STRING | Status of the country |\n| Shape_Area | DOUBLE | Shape area |\n| Shape_Leng | DOUBLE | Shape length |\n| EXP0_YEAR | INT | Expiry year of the administrative unit |\n| STR0_YEAR | INT | Creation year of the administrative unit |\n\n### Terms of Use\n\n**Terms of Use**\n\nThe GAUL dataset is distributed to the United Nations and other authorized\ninternational and national institutions/agencies.
