Using ArcView for Automated Reporting, Mapping, and Analysis of Crime Data-Examples from the Field
Defining Issue: Recently, with growing concerns over crime and violence and an emphasis on community policing, there is high interest in crime analysis technology. Crime analysis relies on historical crime data including crime incident reports, information about various known offender groups (e.g., parolees, sex offenders), and other community information. But efficient reporting, mapping and analysis of individual crime incident and known offender data and synthesis with other community data can be a cumbersome task for a police department. GIS Solution: The Omega Group, an Esri Business Partner, has developed CrimeView, a suite of integrated crime analysis tools designed for use with ArcView GIS Version 3.0. CrimeView serves as an easy access front end to crime reporting, mapping, and analysis routines developed in ArcView using the Avenue programming language. These routines demonstrate the effectiveness of ArcView as a crime analysis tool. Methodology: ArcView Version 3.0 offers the user an
immense set of spatial analysis tools not previously available to a police department in a desktop environment. By developing Avenue scripts, the crime reporting, mapping, and analysis tasks can be refined. CrimeView automates the tasks of crime incident and known offender reporting and mapping, crime density and repeat call investigations, and custom report and map creation. Using these tools, the Redlands Police Department and other law enforcement agencies are now able to move the crime reporting and mapping tasks from the crime analyst to community volunteers, beat officers, watch commanders, and other department staff. The analyst then has the tools and the time to prepare the needed crime trend and ad hoc analyses. These automated routines can work with any ArcView Version 3.0 crime data application. Potential users include any law enforcement agency that wants easy access to geographic crime analysis, reporting, and mapping of their data. Software: The CrimeView interface was written in Delphi,
the routines in Avenue were based on ArcView GIS Version 3.0, and R&R Report Writer is used as a report generator. This paper will present examples of how this product has been incorporated into police departments to facilitate their crime analysis, prevention, and community education efforts.
