14 Calculating points' density within Thiessen polygons (spatial join)
This video shows how to calculate points' density within polygons (Thiessen polygons, in this case). The video takes into account the John Snow's cholera dataset in order to show one of the strategies that can be used to identify which water pump can be considered as causing the outbreak of the disease. The exercise's main goal is to visually represent which area surrounding each individual water pump has the higher density of cholera deaths.
