GGR252H1 Lecture Notes - Lecture 1: Choropleth Map, Geomarketing, Cholera
Document Summary
How best reach the consumers of goods and services. Collected information on where people died (location and geographical) Noticed it was near water pumps and a clustered pattern on broad street. Taking handles off the pump and drops cholera. Distance decay: further from the source in this case pump (source) = less death. Controversy: two outliers where there is increased death. Two outliers: intervened opportunities which can still cause death; intercepts the main water pump, but causes death because they have other duties too. Clients facilities in montreal, quebec choropleth map: shaded differences (in this case household income); higher the values the darker the shade. Distance decay occurs in this situation and the rivers make it even more apparent. Suburban areas have high income levels in distinct areas (corridors) (in a choropleth map with income) comparison to city centers.
