Category killer = single category big box (e.g., Home Depot) that threatens the same department
existing within department stores
Demand-supply pairs
o Customer and store
o Movie patron and cinema
o Customer and bank
o Reader and library
o Patient and hospital
o Student and school
o Whether public or private sector, the objective is to bring the demand and the supply together
o The geography of locational strategy is an important component in bringing the demand and
the supply together
Course emphasis
o Mostly private sector rather than public sector
o Mostly retail examples
o Mostly North American and European examples
o Mostly post 1950
Average household having access to automobiles and accompanying infrastructure
(e.g., power lines, sewer pipes, etc.) facilitated suburbanization (e.g., middle and high
income) in big cities in North America
o Mostly practical, but also academic/theoretical
Spatial concepts and the value of location
o Basic spatial concepts
o Location and demand the spatial demand curve
o Intra-urban retail hierarchies
Hierarchies of services
o Location and competition the hotelling model
o Land value and land use
o Bounding a spatial market
o Models
Describing point patterns
o Regular (uniform)
o Clustered (linear clustered)
Distance decay
Linear clustered population pattern around the Golden Horseshoe
o Random (dispersed)
Distance decay curve (interaction vs. distance)
o With greater from the destination, there is a decrease in attraction
o Distance decay describes a pattern
Disincentive nature of distance (friction of distance)
o Disincentive of nature is the pattern of distance decay
o Cost in time and money to cover distance
o E.g., GTA limousine tariffs
o Range = the point at which interaction reduces to zero because of increased travel costs
Range (e.g., the steepness of the curve) is different for different activities
Convenience store (narrow range) vs. power centre (broad range)

Document Summary

Category killer = single category big box (e. g. , home depot) that threatens the same department existing within department stores. Course emphasis: mostly private sector rather than public sector, mostly retail examples, mostly north american and european examples, mostly post 1950. Average household having access to automobiles and accompanying infrastructure (e. g. , power lines, sewer pipes, etc. ) facilitated suburbanization (e. g. , middle and high income) in big cities in north america: mostly practical, but also academic/theoretical. Spatial concepts and the value of location: basic spatial concepts, location and demand the spatial demand curve. Hierarchies of services: location and competition the hotelling model, land value and land use, bounding a spatial market, models. Describing point patterns: regular (uniform, clustered (linear clustered) Linear clustered population pattern around the golden horseshoe: random (dispersed) Distance decay curve (interaction vs. distance: with greater from the destination, there is a decrease in attraction, distance decay describes a pattern.
