In 1998, when the Hayward California Police Department created its Crime Analysis Unit, it was determined that an assessment was necessary to determine how the department could best utilize crime analysis data to serve the community. The department's first step was to determine its assets. In the review, it was determined that the system currently in use, computer aided dispatch (CAD), records management system (RMS), and the management information system (MIS) was dated. Access to MIS and RMS data in the Crime Analysis Unit was not a feasible way to provide mapping. The solution was small Paradox-based case management system with a separate table for each Part I crime type. The next obstacle was the issue of format and distribution. The platform of distribution became increasing the number of available PCs, creating a Netscape Browser with access to all departments and units, and creating a Crime Analysis Unit Intranet Web site. The article continues with discussions on ongoing capability enhancements and marketing strategies. The implementation of a mapping program within a police department is seen as an ongoing process and consisting of assessing needs, identifying assets, determining data options, making necessary purchases, and deciding formats and frequencies. Decisions need to be made regarding sources of data, mapping software, departmental needs, and available assets.
