System

Oldfield Freya Newman
iOPS is developed as both a research tool and an
operational crime analysis and investigative
decision support system with the Metropolitan
Police Service. It is unique because of its
ability to compare the visualisation of Modus
Operandi and Spatial Mapping, using a
Geographical Information System.
2. Identify offence series
1. M.O. 'heat map'
iOPS allows for the structural analysis of the
co-occurrence of crime scene activity using
multi-dimensional scaling (MDS). A structural
model is presented as a conceptual 'map' that
allows on screen selection of the criminal
actions that co-occur, i.e. distinct sets of M.O.
Behaviours are represented as points within a
Smallest Space Analysis plot. The closer they are
the more often they co-occur. Frequencies
indicated by heat contours (and in parentheses).
These selected sub-sets can be utilized within
the system directly to search the data base and
put matched crimes onto the map.
4. Social Network Analysis

Geographical Profiling procedures for linking
crimes and proposing offender locations.
In-built functionality allows the crimes, or
crime series, identified by the processes
indicated, to be modeled, allowing possible
locations of suspects' known addresses to be
inferred. This can be used to draw out possible
suspects using geographical profiling procedures
and M.O matching and to assign priorities to
them.
Social Network Analysis on and off the map. This
allows for further examination of other nominals
who may be linked to a series of crimes
