ABSTRACT
This research paper puts into operation, the application and
utilization of Geographical Information System (GIS) in
crime management and in security situation analysis for
efficient community policing in Nigeria, using Anaocha as
case study. The aim was to model crime patterns in
Anaocha L.G.A, Anambra state using GIS approach.
Methodology adopted included the acquisition of GPS
coordinates of crime locations, attribute data and analogue
map of Anaocha L.G.A which was scanned and digitized
amongst others. The GPS coordinates of the crime
locations were imported into ArcGIS environment and a
database was designed. The results showed that about 85
out of 88 crimes in the area were committed by males, 27
out of 88 crimes resulted in more than one casualty, 18 out
of 88 crimes were shoplifting, out of 88 crimes there were
just two cases of kidnapping. It was therefore
recommended that the result of this research paper serves
as a decision support system in managing crime within
Anaocha L.G.A of Anambra State, Security agencies like
Vigilantes should complement the efforts of the police in
checking crimes especially in areas with no police posts or
police station amongst other recommendations.

1. INTRODUCTION
Crime mapping involves the manipulation and processing
of spatially referenced crime data in order to display
visually in an output that is informative to the particular
user (Alex and Kate 2001). Crime mapping can provide
information concerning the location of hotspots or high
level of reported crime. Crime analysis is a set of processes
applied on relevant information about crime patterns.
Administrative and operational personnel can use the result
of analysis to prevent and suppress criminal activities and
also for investigation aims. Crime prevention seeks to
reduce the risks of criminal events and related anti-social
behavior by intervening in their causes.
In Anaocha L.G.A, GIS has not yet been viewed as an
obligatory technology within the police force, whereas
organizations such as the utilities have taken GIS on board,
this is due to high cost of GIS tools and lack of GIS experts
in the police force. Law enforcement needs information
management, especially location information. Traditional
law enforcement for different types of police applications
really deals with data collection. However, data collection
without data analysis is useless. GIS not only allows
integration and spatial analysis of data to identify,
apprehend, and prosecute suspects, it also improves more
proactive measures through effective allocation of
resources and better policy setting.
It is quite obvious that if the police authorities have goals
of improving crime management (crime prevention) in the
rural areas, the manual recordings of crime incidents cannot
be the way forward. The various police stations under the
Anaocha divisional headquarters’ office have the
responsibility of handling the various crime incidences
under their jurisdiction but at the moment have problems
with their recording system and aggregation of crimes
incidents in all police stations within their jurisdiction. All
the recordings that are done in the police station are
manually written in blotters (police blotter is a record of all
arrests, crime events, and charges) and it is difficult to do
decision making relating to crime management for all the
police stations in their jurisdictions. There were also, no
system for evaluating the effectiveness of crime prevention
initiatives and assistance in the prevention and rapid
response to crime. Hence, there is no decision support
system for crime management within the Local
Government Area
2. STUDY AREA
Anambra State is one of the five states in the South-Eastern
part of Nigeria (See Fig.2.0a). The state is made up of 21
Local Government Areas (Fig 2.0b) of which Anaocha is
one of them (www.anambrastate.gov.ng/history.html).
Anaocha Local Government Area (Fig 2.0c) covers an area
of 171.62 square kilometers lying within latitude 6
o
12’N
and 6
o
14’N to longitude 6
o
45’E to 7
o
