Topic 3 Flashcards
Spatial Interaction
Movement of goods, people and ideas within the between regions
Globalization
The increasing level of spatial flows, interconnections and interdependence
Ullman’s Model
Identifies factors that influence spatial interaction involving goods
Regional Complementarity
There must be supply or surplus of products in one region, and a demand or deficit another region for regions to interact
Intervening Opportunity
Flows of products between two regions will be restricted if there are intervening sources of supply
Transferability
Refers to the ease of movement of products
Distance Decay
Declining intensity of any activity, process, or function with increasing distance from its point of origin
First law of geography
Everything is related to everything else, but near things are more related than distant things
Friction of Distance
Retarding effect of distance upon spatial interaction
Gravity Model
Model of spatial interaction developed by Henry C. Care int he 1850s
Physical Gravity
Force of attraction declines as the square of distance
Social Gravity
Force of interaction attraction declines at somewhat different rates depending on the domain of interaction
Movement Bias
Any aggregate spatial control on the movement of people, commodities, or communication
Distance Bias
Favours short movements over long movements
Direction Bias
Where actual flows are mainly limited to only one or a few directions
Network Bias
Occurs because the presence or absence of connecting channels strongly affects the likelihood that spatial interaction will occur
Barriers
Impede spatial interaction, either by blocking it totally or slowing it down, or redirecting it
Mobility
General term applied to all types of movement through space and time
Migration
Distinction between temporary travel and is important to a geographic analysis of spatial mobility and is usually fairly clear
Territoriality
Involves an individual or group attempt to identify and establish control over a clearly defined territory considered an exclusive domain
