Fundamental concepts of spatial analysis - lecture notes
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"
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.
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.
