The United States government, led by the U.S. Geological Survey (USGS), has initiated a project to cooperatively develop, market, and distribute The National Atlas of the United States of America. The participation of many agencies of the federal government has been crucial to the successful development of the National Atlas. Congress recognized that no single government agency could deliver an atlas that is truly national in scope and breadth when it assigned the USGS to direct the project. That's why so many Federal producers of reliable and authoritative geographic information have joined in developing National Atlas products.
