In 2010 I completed a Master of Applied Science (Spatial Information Science) at the University of Sydney. Working with Dr. Eleanor Bruce I produced the thesis entitled ‘Graffiti and Urban Space: A GIS Approach’. The work examined spatial and temporal patterns of graffiti occurrence in the City of Sydney local government area, utilizing both council supplied data on graffiti removal, geocoded and analysed in ArcGIS, and graffiti incidence data collected using a handheld GPS and ArcPad. Cluster analysis was performed to determine graffiti removal hotspots. The research presents graffiti as a diverse urban culture, provides evidence for the ineffectiveness of ‘rapid removal’ and ‘zero tolerance’ approaches to graffiti management, and highlights benefits of a GIS approach.

The purpose of this project was to employ spatio-temporal analysis techniques within a GIS to test some of the popular claims about the effectiveness of rapid removal graffiti policies. The policy informs that rapid removal will deter graffiti writers and reduce overall quantities of graffiti. However, research has suggested that this approach does not reduce overall graffiti but rather triggers changes in location and form. Findings of my research provide evidence for the latter.
This project demonstrated the value of GIS in spatially assessing diverse phenomena in the urban environment. The project provides important quantitative evidence to complement existing qualitatively derived theories. Previously, quantitative work that had been undertaken in this area focussed almost exclusively on criminology. Significantly, my work extended spatio-temporal analysis of graffiti to examine the broader spatial practice of urban graffiti writing as a diverse cultural phenomenon. The project findings contribute to formulating better informed strategies for graffiti management – an important and relevant task for cities the world over.
