The digital transformation does affect geographical space. The way in which we interact with spaces has therefore changed considerably in recent years. We post our locations on Facebook, follow space-related recommendations on Tripadvisor and generate new types of spaces on Twitter at the intersection of the digital and physical. Likewise, digital logics, economic models, and social infrastructures have permeated our space and place-making processes. These developments, which are summarised here under the term "digital geography", also lead to changes in spatial planning. On the one hand, spatial planners must adapt to the changed ways in which people produce and interact with spaces, and take this into account in planning processes. On the other hand, planning processes themselves are also affected by the outlined developments.

This lecture offers an up-to-date, synoptic, and critical overview of how digital instruments, logics, methods, etc. influence and change geography as a spatial science and thus also spatial planning. The following topics are covered:

• Digitalisation as a sociospatial system
• Digital space concepts
• Sources of digitally shaped evidence
• Digital methods
