Document Summary
Spatial interaction: amount of movement or communication between two locations. Distance decay: how the level of interaction declines as distance increases, the decline of an activity or function with increasing distance. Friction of distance: distance has a retarding effect on interactions. Accessibility and connectivity: critical for the nature and level of spatial interaction. The ease with which distance can be crossed. The tangible and intangible ways that places are. Friction of distance connected: how easy or difficult it is to overcome the distances that separate places. But think about it: air canada doesn"t go to africa! Gravity models: measuring the quantity of movement or interaction between two places. Diffusion: the process by which a characteristic spreads across space, from one location to another, over time. Depends on distance, friction of distance, and densities of population. Relocation diffusion: the spread of an idea or characteristic through the physical movement of people form one location to another.
