Background Information
Sample map Sample Map
The boundaries of the United States resulted from treaties, purchases, colonial charters, and acts of Congress. Nature also sets and alters natural boundaries in coastal zones. An excellent history of America's national and state boundaries was authored by Franklin K. Van Zandt and published by the U.S. Geological Survey as Professional Paper 909 back in 1976. Google now offers this at no cost as an electronic book.

The One Million-Scale National Boundaries of the United States map layer includes the boundaries for the Nation, which includes the 50 States, the District of Columbia, the Commonwealth of Puerto Rico, and the U.S. Virgin Islands. National boundaries are also included in other National Atlas map layers, including: One Million-Scale State Boundaries of the United States and One Million-Scale County Boundaries of the United States. We also offer a Printable Map and map layer showing the history of Territorial Acquisitions in the United States.

This map layer was produced by the National Atlas of the United States. It is part of our collection of fundamental digital cartographic data known as 1. This collection includes base map data in vector format at 1:1,000,000-scale and in image format at 100-meter resolution. Read more about the 1. A Global Map edition of this map layer is also available.

In cooperation with national mapping programs in Canada and Mexico, we also produce a map layer of political boundaries across North America.
