The Geological Survey of Canada, U.S. Geological Survey, and Consejo de Recursos Minerales of Mexico have compiled aeromagnetic data to produce a database and digital map for the North American continent. The unified data set is a powerful tool for determining structure, geologic processes, and tectonic evolution of the continent and can be used to help resolve societal and scientific investigations that span national boundaries.
