In this I paper I explore the need for a new field of geographic enquiry called cybergeography. This is the investigation of the complex and multifaceted structure, use and experience of the online world inside global computer-communications networks, most obviously represented by the Internet and the World-Wide Web. In particular I focus on how one can study the geography of Internet diffusion from publicly available statistics. Then I consider ways that the landscapes of Cyberspace can be mapped to enhance our understanding of their evolving form and texture using examples of a real-time "weather map" of Internet congestion and maps of the urban structure of virtual world.

Introduction One definition of the Internet is: "a collection of resources that can be reached from those networks" (Krol & Hoffman 1993, page 1) This definition by Krol & Hoffman provides the starting point for my conceptualisation of accessibility in the Information Age. I will examine how one can begin to measure and visualise the aspects of accessibility to resources within the Internet. I start my discussion with the assumption that a person has physical access to the Internet, via a networked computer. I also take a broad view of accessibility, going beyond formal mathematical models to consider wider issues. There are many important dimensions to accessibility beyond simple Internet connectivity which need to be considered and in some manner measured and mapped. Once you have, what could be termed, `physical' access to the Internet, how accessible are the information resources, people and electronic places available online? Fo
