Data Download - Global Map Data

North American Atlas map 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 National Atlas of the United States program supplies all American data to the Global Map and represents America on the International Steering Committee for Global Mapping.

The National Atlas publishes two data collections at one million-scale: one for Global Map users and one for National Atlas 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 Atlas vector data includes all of the Global Map data fields and attributes plus those in the National Atlas data dictionary.

An informative page of Global Map Frequently Asked Questions is available online.
