Case studies cover a range of topics: documenting changes to land use and cover; analyzing the movement and flows of people and information; assessing the role of governance and policy; measuring the impact of technology, infrastructure, and engineering; and determining the influence of economics and finance. They reveal that individual cities possess their own character determined largely by their history, physical environmental, regional to global standing, and—perhaps most importantly—the people living there.
