Per the Federal Geospatial Data Committee (FGDC), this theme is defined as the “boundaries that delineate geographic areas for uses such as governance and the general provision of services (e.g., states, American Indian reservations, counties, cities, towns, etc.), administration and/or for a specific purpose (e.g., congressional districts, school districts, fire districts, Alaska Native Regional Corporations, etc.), and/or provision of statistical data (census tracts, census blocks, metropolitan and micropolitan statistical areas, etc.). Boundaries for these various types of geographic areas are either defined through a documented legal description or through criteria and guidelines. Other boundaries may include international limits, those of federal land ownership, the extent of administrative regions for various federal agencies, as well as the jurisdictional offshore limits of U.S. sovereignty. Boundaries associated solely with natural resources and/or cultural entities are excluded from this theme and are included in the appropriate subject themes.” For other NGDA Content: Esri Federal Datasets美国土地管理局（Bureau of Land Management, BLM）国家行政单元——州级要素图层。本要素图层采用美国土地管理局（BLM）提供的国家地理空间数据资产（National Geospatial Data Asset, NGDA）数据，用于展示美国境内的行政州界。根据BLM的规定，各州“负责管理公共土地上的各类活动，涵盖休闲、牧场经营、林业、矿产开发、水资源管理、鱼类与野生动物保护、荒野区域保护、大气与土壤保护，以及景观、科学与文化价值保护等相关工作”。 东部各州数据下载日期：2026年4月2日（04/02/2026）。 数据源：BLM国家行政与管理单元（ADMU）行政边界多边形及办事处点位数据集。 NGDAID：186（BLM国家行政与管理单元行政边界多边形及办事处点位数据集）。 OGC要素服务链接：（美国土地管理局国家行政单元——行政州界），请复制该链接以嵌入符合OGC标准的可视化工具中。 如需了解更多信息，请参阅：BLM国家行政与管理单元行政边界多边形及办事处点位数据集支持文档：元数据。 反馈联系方式：请发送邮件至[e-mail]。 本数据集隶属于NGDA的“政府单元与行政及统计边界”主题数据集群落。根据联邦地理数据委员会（Federal Geospatial Data Committee, FGDC）的定义，该主题涵盖“用于治理与常规公共服务（如州界、美洲印第安保留地、县界、城市、城镇等）、特定行政用途（如国会选区、学区、消防区、阿拉斯加原住民区域公司辖区等），以及统计数据发布（如普查分区、普查街区、大都市及小城市统计区域等）的地理区域边界”。 此类各类地理区域的边界，要么通过正式的法律描述进行界定，要么依据既定标准与指南划定。其他边界类型还包括国际界限、联邦土地所有权边界、各联邦机构的行政区域范围，以及美国主权管辖的近海界限。 仅与自然资源和/或文化实体相关的边界不纳入本主题范畴，而是归入对应的专业主题数据集。 其他NGDA相关内容请参阅：Esri联邦数据集。
