QUESTION 1.1
Effective crime analysis is essential for informed decision-making and
proactive policing. Two key analytical tools used in crime intelligence
are the Geographic Information System (GIS) and Crime Pattern
Analysis (CPA). Although closely related, each tool documents different
types of information and serves distinct operational and strategic
purposes in policing.
Geographic Information System (GIS)
The Geographic Information System (GIS) is an electronic crime-
mapping tool that documents spatial and temporal information
relating to reported crimes within a specific policing area. It operates as
a centralised database that receives crime data captured through the
Crime Administration System (CAS) when cases are reported at police
stations.
Firstly, GIS records the CAS number for each reported crime, which
uniquely identifies every incident. This allows investigators and analysts
to track, reference, and cross-check crime reports accurately.
Secondly, GIS documents the date and time of occurrence of each
crime. This information assists in identifying peak crime periods, such as
crimes occurring at night, over weekends, or during specific seasons,
which is vital for crime trend analysis.
