Fundamental concepts of spatial analysis - lecture notes
Location:
nominal place names
absolute mathematical coordinate systems/ GPSrelative site and
situation
cognitive mental maps, perception, opinion
The first law of geography:"Everything is connected to everything else, but near things are more related than are distant things"
Distance:
absolute miles, kilometers, feet
relative in terms of time, effort, cost
cognitive personal judgements
Friction of distance: the deterrence or inhibition of distance
Distance decay function: the rate at which a process or activity diminishes with distance.
Space:
absolute square miles/kilometers
relative topological space: connectivity of points in space
cognitive defined and measured by values, feelings, beliefs, perceptions.
Accessibility:opportunity for contact or interaction between locations influenced by connectivity and barriers.
What are the fundamental principles of spatial interaction ? Complementarity, Transferability, Intervening opportunity, diffusion
Complementarity: supply and demand between places
Transferability: cost and ability to move something
Intervening opportunity: alternatives along the way
Diffusion: the spread of a phenomenonstructural vs. dispersal characteristics.
