Figure 5: The human footprint index clearly shows metropolitan areas in the northeastern United States. In addition to Boston and New York, which are labeled, it's easy to pick out Providence, RI, Hartford, CT, Springfield, MA, Worcester, MA, and Portland, ME. If you know the freeways in the area, it's not hard to pick out I-95, I-91, I-90, and others.
