전 세계 행정 단위 레이어 (GAUL)는 전 세계 모든 국가의 행정 단위에 관한 최상의 정보를 수집하고 배포하여 행정 단위를 나타내는 공간 데이터 세트의 표준화에 기여합니다. GAUL은 항상 국가, 1차 (예: 부서), 2차 행정 수준 (예: 지역)에서 통합된 코딩 시스템을 사용하여 전역 레이어를 유지합니다. 데이터가 제공되는 경우 국가별로 3, 4단계 이하의 레이어를 제공합니다. 전반적인 방법론은 a) 가장 신뢰할 수 있는 소스에서 사용 가능한 최상의 데이터를 수집하고, b) 지리적 특징의 검증 기간을 설정하고 (가능한 경우), c) UN 지도 제작 부서 (UNCS)에서 제공한 마지막 국가 경계 지도에 따라 선택한 데이터를 전역 레이어에 추가하고, d) GAUL 코딩 시스템을 사용하여 코드를 생성하고, e) 사용자에게 데이터를 배포하는 것으로 구성됩니다(GAUL 배포 세트의 기술적 측면 참고).
일부 행정 단위는 멀티폴리곤 기능입니다.

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://sgst.wr.usgs.gov/gfsad30/FAO_GUAL/TechnicalAspectsGAUL2015_Doc1.pdf)).\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| ADM2_CODE | INT | GAUL code of administrative units at second level |\n| ADM2_NAME | STRING | Name of administrative units at second level |\n| EXP2_YEAR | INT | Expiry year of the administrative unit |\n| STR2_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.
