Les couches d'unités administratives mondiales (GAUL) compilent et diffusent les meilleures informations disponibles sur les unités administratives de tous les pays du monde, contribuant ainsi à la normalisation de l'ensemble de données spatiales représentant les unités administratives. La GAUL conserve toujours des calques mondiaux avec un système de codage unifié au niveau des pays, des divisions administratives de premier niveau (par exemple, les départements) et de deuxième niveau (par exemple, les districts). Lorsqu'elles sont disponibles, les données fournissent des calques pour chaque pays, jusqu'aux niveaux inférieurs. La méthodologie globale consiste à : a) collecter les meilleures données disponibles auprès des sources les plus fiables ; b) établir des périodes de validation des caractéristiques géographiques (lorsque cela est possible) ; c) ajouter les données sélectionnées à la couche globale en fonction de la dernière carte des limites des pays fournie par l'unité cartographique des Nations unies (UNCS) ; d) générer des codes à l'aide du système de codage GAUL ; e) distribuer les données aux utilisateurs (voir Aspects techniques de l'ensemble de distribution GAUL).
Notez que certaines unités administratives sont des entités multipolygones.

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| ADM1_CODE | INT | GAUL code of administrative units at first level |\n| ADM1_NAME | STRING | Name of administrative units at first level |\n| EXP1_YEAR | INT | Expiry year of the administrative unit |\n| STR1_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.
