ArcGIS Server-based tool mitigates graffiti By Matt Keeling, City of Riverside, California A comprehensive application developed by a Southern California city not only helps identify and prosecute the vandals who produce graffiti but also tracks the entire cost of graffiti to the city. The Public Works, Police, and Information Technology departments of the City of Riverside have developed the Graffiti Abatement Tool (GAT) to coordinate interdepartmental efforts and address the problem of connecting instances of graffiti to an individual vandal (or tagger). GAT, a custom application, was built using ArcGIS Server, ArcSDE, and several other technologies. It stores and manages images of graffiti with other tabular data useful Above: Public Works crews that remove graffiti first take a picture of the graffiti using a Ricoh GPS camera and complete a customized digital form on the camera. Right: The Graffiti Abatement Tool (GAT) helps identify and prosecute the vandals who produce graffiti and also tracks its entire cost to the city. 16 ArcUser Summer 2009 www.esri.com
