GGR252H5 Lecture Notes - Lecture 5: Voronoi Diagram
Document Summary
Draw construction lines between centre and all adjacent centres. Bisect each of the construction lines: measure exactly halfway along each line. Extend the bisectors at right angles to the construction lines until they meet other extending bisecting lines. This produces spatial monopoly trade area around each of the centres. The problem of partial cts: assume an even population dispersion (when counting grids) What would happen if we change the scenario in the future. Can address many what if questions: address the question before its carried out. Look at large polygons first because they involve large distances travelled: but it may be because theres not that much people in that area. Look at the intersection/vertices (more intersection the better: good sites because. Market point of view relatively far/poorly serviced areas: don"t put in rivers or residential area, the gravity model will only be relevant if the store is attached to different size malls. First the stores are targeted towards suburbs.
