1. The North American Long Haul Fiber Optic Network

This map is a fiber density analysis of the North America long haul fiber optic network. The height of the peaks is determined by a ratio of the density of fiber and the amount of geographic routing diversity in an area. The blue lines represent long haul fiber pathways. The map demonstrates the dominance of the coasts in information infrastructure as well as a few key routing hubs connecting the coasts.


2. The North American Long Haul Fiber Optic Network

Another visualization technique for the North American long haul fiber network.


3. Fiber Heat Map with Population Densities

This image shows a heat map of fiber densities in North America. The white dots show populated places shaded from gray to white with white dots having higher population and gray dots lower population.


4. The North American Gas Pipeline Network

This map is a density analysis of the North American gas pipeline network. The height of the peaks is determined by a ratio of the density of gas pipelines and the amount of geographic routing diversity in an area. The map illustrates the predominance of the oil production areas in Texas, Louisiana, and Oklahoma, which differs significantly from the other critical infrastructures analyzed.


5. The North American Electric Power Grid

This map is a density analysis of the North American electric power grid. The height of the peaks is determined by a ratio of the density of power transmission lines and the amount of geographic routing diversity in an area. The map shows the more evenly distributed nature of the power grid, which matches the universal demand for electric power.


6. Power Grid August 2004 Blackout

The electric power grid density analysis points out an interesting finding. The highest density of electric transmission lines with the least amount of diversity coincides with the area in Ohio that has been named as the origin of the Northeast Blackout in August of 2003.


7. Interdependency Visualization for the Fiber and Power Grids

This map combines the fiber and power grids to analyze where there are common geographic interdependencies between the two critical infrastructures.


8. Interdependency Visualization for the Fiber, Power, and Gas Networks

This map combines the fiber, power, and gas networks to analyze where there are common geographic interdependencies between the three critical infrastructures. A plane is then added to illustrate points of density above a specific threshold.


9. Overlay of the Fiber, Power and Gas Networks

In this map the three infrastructure networks are not combined, but instead overlaid on top each other to provide a skeleton view of their spatial interaction. Fiber lines are white, electric transmission lines are green, and gas pipelines are orange.
