Kernel Density (Incidents of Substance Release)<\/h3>\n

Dependent Variable: Incidents of Substance Release<\/h4>\n

Combining the two point files of locations of releases, a Kernel Density surface was created and then reassigned a value between 0 and 1 using Fuzzy Membership – Linear. Higher values represent a higher density of releases. Each density value was then multiplied by 100 to allow for a range between 0 to 100. Next, the raster surface was transformed to a point surface and spatially joined to\u00a0 dissemination areas (DA) in greater Edmonton (census division No.11). The points were then averaged within each DA (merge rule = mean).<\/p>\n

Kernel Density (Incidents of Crude Oil Release)<\/h3>\n

Dependent Variable: Incidents of Crude Oil Release<\/h4>\n

In the second kernel density, only crude oil releases were included. The kernel density was weighted by the volume released. Similar to the previous kernel density, the raster was reassigned a value from 0-100 and values were averaged for each DA.<\/p>\n
