In chapter 2, we focus our attention on the interesting intersection of cyberspace and geographic space. Here, we present maps of the infrastructure that supports cyberspace, the demographics of cyberspace users, and the flow of data traffic across different scales from the local to the global.The examples discussed predominantly map the data from which they are constructed onto familiar geographic frameworks, although a few use a more abstract approach.These maps provide important insights into who owns and controls the supporting infrastructure, who has access to cyberspace, how the system can be surveyed, and how and from where cyberspace is being used. Often they are most useful for public understanding because a familiar template of real-world geography is used.
