Sample MapInitial 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 – Railroads data set shows the railroads of North America at 1:10,000,000 scale. The railroads included are either rail links between major centers of population or major resource railways. There is no classification of rail lines. 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, roads, and sea ice. |
