After further research and consultation with my thesis committee, I have shifted the direction from being a multilayer interactive crime mapping prototype simulation to focusing on a specific aspect of the mapping being the symbols. The map symbols are lacking in design, effectiveness, communication of the idea or action, consistency, and quantitative and qualitative data. Therefore, my thesis has shifted to create a series of symbols sets that span four categories of public safety data including search and rescue, emergency response, officer field data and crime data. These areas lack symbols as well as clear communicating symbols. I aim to effectively synthesize and standardize a symbol system to be used in crime mapping applications for police agencies throughout the country. This was realized after finding that all police departments use Arc GIS to map crime and through reading various resources but particularly these following article links from the National Criminal Justice Reference Service:
