The Global Map is an international effort by national mapping organizations to produce consistent and accurate mapping data of the world at a scale of 1:1,000,000. The 1997-2014 Edition of the National Atlas of the United States originally supplied all American data to the Global Map. The National Map will continue to publish two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features. The Global Map edition includes just the data fields and attribute values in the Global Map Specifications Version 2.2. National Map vector data includes all of the Global Map data fields and attributes plus those in the National Map data dictionary.
