Acrylic Print

This was printed on a 30″ x 30″ sheet of acrylic.

The Source Data

The crime data can be downloaded from CivicApps, Portland’s data portal. Here’s a direct link to the FTP site that contains multiple years of data. The crime data was filtered to only include DUIs. As always when looking at crime data, remember this is where the most people are arrested, which isn’t necessarily the same as where the most people are actually driving drunk.

The street data was an extract taken from OpenStreetMap, provided by MapZen. The street data itself is copyright OpenStreetMap contributors.

The satellite imagery was from the National Agriculture Imagery Program (NAIP) and was downloaded through the Oregon Imagery Explorer.
