U.S. National Grid

U.S. National Grid This feature layer, utilizing data from the Federal Geographic Data Committee (FGDC), displays the U.S. National Grid (USNG). The FGDC provides standards for a National Grid. Per the FGDC, "The objective of this standard is to create a more favorable environment for developing location-based services within the United States and to increase the interoperability of location services appliances with printed map products by establishing a nationally consistent grid reference system as the preferred grid for National Spatial Data Infrastructure (NSDI) applications. This standard defines the US National Grid. The U.S. National Grid is based on universally defined coordinate and grid systems and can, therefore, be easily extended for use world-wide as a universal grid reference system." Notes: Popups can be viewed for the USNG 1000m and USNG 100m layers. The USNG 100m layer is only displayed for certain cities. To view those places, please select a row in the attribute table and then center (zoom) on selection. U.S. National Grid - Grid Zone Designations Top: 100,000-meter and 10,000-meter Square Identifications Bottom: 1,000-meter and 100-meter Square Identifications Data downloaded: 2025 Data source: USNG GDB Data modifications: The Percent Complete field was removed from all layers. The following fields were added to the original data for layers: USNG 1000m - UTM Zone USNG 100m - Place; Region For more information: Standard for a U.S. National Grid United States National Grid How to read a United States National Grid (USNG) spatial address For feedback, please contact: [e-mail] Federal Geographic Data Committee (FGDC) Per the FGDC, "The Federal Geographic Data Committee (FGDC) is an organized structure of Federal geospatial professionals and constituents that provide executive, managerial, and advisory direction and oversight for geospatial decisions and initiatives across the Federal government. In accordance with Office of Management and Budget (OMB) Circular A-16, the FGDC is chaired by the Secretary of the Interior with the Deputy Director for Management, OMB as Vice-Chair."美国国家网格（U.S. National Grid）本要素图层依托联邦地理数据委员会（Federal Geographic Data Committee, FGDC）的数据，展示美国国家网格（USNG）。FGDC为国家网格制定了相关标准。根据FGDC的表述：“本标准的目标是打造更有利于美国境内基于位置服务开发的环境，并通过建立全国统一的网格参考系统作为国家空间数据基础设施（National Spatial Data Infrastructure, NSDI）应用的首选网格，提升位置服务设备与印刷地图产品的互操作性。本标准定义了美国国家网格。美国国家网格基于通用定义的坐标与网格系统，因此可作为通用网格参考系统轻松扩展至全球范围使用。” 备注：可查看USNG 1000m与USNG 100m图层的弹窗信息。USNG 100m图层仅在部分城市中显示。若要查看这些区域，请在属性表中选中某一行，随后以选中项为中心进行缩放（居中放大）。 美国国家网格——网格区域标识 上部：100,000米与10,000米方格标识 下部：1,000米与100米方格标识 数据下载时间：2025年 数据源：USNG GDB 数据修改说明：所有图层均已移除“完成百分比”字段。以下字段已添加至各图层的原始数据中： - USNG 1000m图层：UTM分区（UTM Zone） - USNG 100m图层：地点（Place）、区域（Region） 更多参考资料：《美国国家网格标准》《美国国家网格》《如何读取美国国家网格（USNG）空间地址》 如需反馈，请联系：[e-mail] 联邦地理数据委员会（FGDC）根据FGDC的表述：“联邦地理数据委员会（FGDC）是由联邦地理空间专业人员及相关方组成的组织架构，为联邦政府跨部门的地理空间决策与举措提供执行、管理、咨询指导及监督。根据《管理与预算办公室（Office of Management and Budget, OMB）A-16号通告》，FGDC由内政部长担任主席，管理与预算办公室分管管理的副主任担任副主席。”
