The city forms a compressed web of diverse spaces. It’s about the built environment, but just as well about visual information or social interactions defining spatial (and readable) relationships. Through the digital networks of cities and their inhabitants, diverse semantic aspects of urban spaces and their temporal occurrence become visible. Contrary to the idea of an immaterial digital level, as described by postmodernism, digitality in many ways forms the physical appearance of the city and its dynamic use. What are the opportunities for innovation and orientation arise from these developments? How can designers not only make them readable, but also be a driving force in defining them? Specific examples from research and practice will be taken as a reference for discussion.
