Figure 2. Spatial effect area development. The figure on the left depicts the Thiessen polygons generation process for every individual segment in the analysis. Each segment was assigned a center point, and the surrounding area was expanded into polygon form until the boundary became closer to a different segment. The blue polygons depict the spatial effects area around a recreational dispensary segment (yellow polygon). The figure on the right details the segments included in the spatial effects area analyses for each dispensary type (black segments). The black segments represent those those that are adjacent, spatial neighbors in a queen’s contiguity matrix to a dispensary segment (red).
