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| 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.
