Digital Infrastructures

Beneath the roads, waterways, satellites, and power lines we can see sits a hidden layer of digital systems. These systems increasingly act as a support structure for the physical networks themselves, gathering information on how much they are used, how well they perform, how dependable they are, and how secure they remain. Rae Zimmerman examines this technological layer from several disciplines at once. Case studies of particular civil and environmental infrastructure sit alongside wider questions of policy and management. The book also considers how information technology can be used to run these vital systems during emergencies.
