Overbrook-McArthur neighbourhood with pycnophylactic surface (see text) of average block aesthetic index scores \(\left( \bar{{s_{i \cdot } }} \right)\). The audit locations are shown as points, with the calculated \(s_{i \cdot }\) (in light gray font, top right of each audit location). Audit locations in 2011 (n = 4) and 2012 (n = 5) are shown for reference. Google Street View (© 2015 Google) panoramas represent example block faces in areas with different \(s_{i \cdot }\) values.
