Historical Physical Points in the Geographic Names Information System (GNIS)

Historical Physical Points in the Geographic Names Information System (GNIS) This feature layer, utilizing National Geospatial Data Asset (NGDA) data from the U.S. Geological Survey, displays physical points from the Geographic Names Information System (GNIS). Per USGS, “The Geographic Names Information System (GNIS) was developed by the U.S. Geological Survey (USGS) in cooperation with the U.S. Board on Geographic Names (BGN), which maintains cooperative working relationships with Federal partners, State Names Authorities, and local and Tribal governments to standardize geographic names for Federal use. GNIS contains information about the official names for geographic features in the 50 States, the District of Columbia, and the dependent areas of the United States, as well as Antarctica. GNIS is the geographic names component of The National Map. GNIS contains records for over one million domestic geographic features in the United States, including populated places, lakes, streams, summits, valleys, and ridges.” Note: Population data is based on 2020 from the Census Bureau. However, the Federated States of Micronesia population data is a 2024 estimate.

美国地质调查局地理名称信息系统（Geographic Names Information System, GNIS）历史实体点位
本要素图层采用美国地质调查局（U.S. Geological Survey）发布的国家地理空间数据资产（National Geospatial Data Asset, NGDA）数据，展示地理名称信息系统（GNIS）中的实体点位数据。据美国地质调查局（USGS）介绍：「地理名称信息系统（GNIS）由美国地质调查局（USGS）联合美国地名委员会（U.S. Board on Geographic Names, BGN）共同开发。后者与联邦合作伙伴、各州地名管理机构以及地方与部落政府保持协作关系，旨在为联邦用途统一规范地理名称。GNIS收录了美国50个州、哥伦比亚特区、美国属地及南极洲境内地理实体的官方名称信息。作为《国家地图》（The National Map）的地理名称模块，GNIS存储了美国境内超百万条地理实体记录，涵盖居民地、湖泊、溪流、山峰、山谷与山脊等类型。」
注：人口数据来源于美国人口普查局2020年统计结果，但密克罗尼西亚联邦的人口数据为2024年估算值。
