3-D Economic Maps from Yale
The G-Econ Project was designed by researchers at Yale to display the world's economic activity using a one-degree grid. A map of the world and maps of individual countries and data sets are available at the project website, http://gecon.yale.edu.
The basic metric is the regional equivalent of gross domestic product. The economic activity displayed on the maps matches closely to cities and areas of large industrial activity, as shown on this map of Canada. Most of the cities of Canada are along the border with the United States, and the economic activity matches that trend.
Professor William Nordhaus of Yale is the project director. The GIS lab in the Geospatial Center & Map Collection in Bracken Library is available for GIS users working on similar projects.
