EM Systems' Crime Mapping Application (CMA) provides law enforcement a visual of criminal activity, including complaints, incidents, arrests and/or user defined data. The system can also be used to map parolees or suspects.

Geographic Information Systems (GIS) create digital representations that enable users to examine data analytically, not just visually. Mapping crime, using GIS, allows crime analysts to identify crime hot spots, along with other trends and patterns. Crime analysts use crime mapping and analysis to help law enforcement management to make better decisions, target resources, and formulate strategies, as well as for tactical analysis (e.g. crime forecasting, geographic profiling).

Mapping allows users to understand where crime is occurring, determine crime patterns, identify areas of high crime density and possible linkages between crimes. Crime mapping can help law enforcement identify the underlying conditions that give rise to crime problems, as well as assess the effectiveness of responses to those problems. Crime mapping provides law enforcement agencies with a powerful tool to aid in crime control and crime prevention efforts.
