2. Agenda Why Crime visualization Background
2D Crime Visualizing- Pin Map
3D Crime Visualising
Crime mapping
Crime network
Hotspots
For crime visualization I will talk about different techniques

3. How often? Crime Every One murder 34.5min One Forcible Rape 6 min
Robbery
1.3 min
Vehicle theft
39.7 sec
Assault
39.1 sec
Violent Crime
23.9 sec
Burglary
14 sec
Larceny
5 sec

4. why
If the central person is found, it become easier to look for other issue
Solving crime faster will pay for itself
Important attributes for each crime category
Locate the crime pattern
Predict crimes
Finding patterns of terrorist attacks
Finding the patterns of reported crimes

5. Efficient?
A. Breuer, J. Hursey, T. Stroman, and A. Verma, “Visualization of Criminal Activity in an Urban Population,” Artif. Crime Anal. Syst. Using Comput. Simulations Geogr. Inf. Syst., p. 35, 2008.

6. London crime statistic sculpture
the frequency & position of urban crimes

7. Pin map

8. Geo-spatial plot of crimes
S. Nath, “Crime pattern detection using data mining,” Web Intell. Intell. Agent Technol. …, vol. 1, no. 954, p. 4, 2006.

9. Advantages
Simplicity
Familiarity
Good feel for the density and distribution crime
Good overall picture
Disadvantages
Can be crowded- less accuracy
Not easy in reality
Just two dimensional

10. Pseudo—Coloured Time-Window
It presents and animates data within a two dimensional system
“Animations of Crime Maps Using Virtual Reality Modeling Language.” Available:

11. Advantages
Useful in depicting the shifting of hot spots of crime as time advanced
Useful for different types of crime in different regions
Animation displays slow emergence of hot spots and their attributes
Disadvantages
Difficult to track when more than one centre need attention at the same time

12. Stacked Time-Aggregated Cumulative Bars
It is a 3D version of pin map where all crime types of same kind have been aggregated over a given time.
Animations of Crime Maps Using Virtual Reality Modeling Language.”

13. Advantages
Find of the coincident of crimes happening together
Comparing two different time zone
Users have ability to fly through or walk though the map
Disadvantages
Information regarding the order of in which the crimes took place are lost

14. Hot Spots Areas of concentrated crime.
Computerized crime mapping develops hot spots approach for policing
Wildly used in analysing the spatial characteristic of crime

16. Density Map: crimes in the street March 2013
O. Kounadi, K. Bowers, and M. Leitner, “Crime Mapping On-line: Public Perception of Privacy Issues,” Eur. J. Crim. Policy Res., vol. 21, no. 1, pp. 167–190, 2014.

17. Answers the questions of “Why” and “Where” Disadvantages
With a target crime being selected, finding hot spots helps crime prediction
Crime opportunity
Answers the questions of “Why” and “Where”
Disadvantages
Some other factors such as population should be considers for accuracy
D. Wang, W. Ding, H. Lo, T. Stepinski, J. Salazar, and M. Morabito, “Crime hotspot mapping using the crime related factors—a spatial data mining approach,” Appl. Intell., vol. 39, no. 4, pp. 772–781, 2012.

18. Crime Networks
The highest priority in front of criminal network investigators
The most central person
Helps for decision making
In the other side
It is based on the research work
Updating is hard
