Background Information
Sample map Sample Map
The North American Atlas is a cooperative project involving the Atlas of Canada, which is part of Natural Resources Canada; Mexico's National Institute of Statistics and Geography (Instituto Nacional de Estadística Geografía e Informática – INEGI); and the National Atlas of the United States®.

Initial North American Atlas efforts have focused on production of standardized geospatial data sets at 1:10,000,000 scale, such as boundaries, water features, and transportation networks. These basic data layers have been integrated so that their relative positions are correct. The data are intended to provide a continental view useful for studying issues that cross political boundaries, such as energy use, the generation of greenhouse gases, water quality, avian migration, and biodiversity. Wall maps and additional data layers are planned for the future.

This collection of data sets forms a base with which other North American thematic data may be integrated. Any data outside of Canada, Mexico, and the United States of America included in the North American Atlas data sets is strictly to complete the context of the data.

The three national atlas programs work collaboratively to produce the trilingual data and documentation and to make the data sets available online. The North American Commission for Environmental Cooperation (CEC) provides coordination activities, and is adopting the North American Atlas frameworks (fundamental map layers, such as streams, roads, and boundaries) as an integral piece of its information management strategy. The CEC is an international organization created by Canada, Mexico, and the United States of America under the North American Agreement on Environmental Cooperation (NAAEC). It was established to address regional environmental concerns, help prevent potential trade and environmental conflicts, and to promote the effective enforcement of environmental law. The Agreement complements the environmental provisions of the North American Free Trade Agreement (NAFTA).

The North American Atlas – Sea Ice data set shows the approximate extent of marine areas in the Arctic covered by permanent polar ice. The data originated from the Canadian Ice Service and shows the average minimum ice limit over a 30 year period, 1969-1999. This data set was compiled by the Atlas of Canada, INEGI, and the National Atlas of the United States®. This data set is available for download only; it cannot be viewed in the National Atlas Map Maker.

The North American Atlas also includes data sets showing bathymetry, glaciers, hydrography, political boundaries, populated places, railroads, and roads.
