GaWC provides a geographic and economic based overview of the world and its evolving configuration. Particularly relevant in this discourse is its categorization of world cities into α, (β and γ tiers, based upon their international connectedness.
If the world is observed from the point of view of the connectivity of the world cities, a new image emerges, where each city is virtually oriented to other cities of the same level of inter*connectivity. National or continental maps give way to a new world configuration intended as an archipelago, where each city appears utterly separated from its geographical surrounding and closer to other cities of the same level. The leading parameters for the new configuration are based on mutual connections, primarily in the global economic system.
The atlas shows the world cities according to the GaWC categorization of 2010. From this, a new configuration emerges, where expected national and local boundaries are presented in their real disposition based upon their international connectedness.
